  12. Effective geoscience pedagogy at the undergraduate level

    NASA Astrophysics Data System (ADS)

    Warden, Kelsey

    This investigation used constructivist pedagogical methods within the framework of an introductory level undergraduate geoscience course to gauge both the changes in attitude and cognition of students. Pedagogy was modified in the laboratory setting, but maintained in the lecture setting and homework. Curriculum was also maintained in the lecture, but was changed in the laboratory to emphasize the large concepts and systems stressed in Earth Science Literacy Principles. Student understanding of these concepts and systems was strengthened by factual knowledge, but recall and memorization were not the goal of the laboratory instruction. The overall goal of the study was to build student understanding more effectively than in previous semesters such that the students would become Earth Science literate adults. We hypothesized that a healthy comprehension of the connections between the human population and Earth's systems would lead to improved cognition and attitude toward Earth Science. This was tested using pre- and post-testing of attitudes via an anonymous survey on the first and last days of the laboratory, student responses to the end-of-course evaluations, and student performance on early-semester and late-semester content testing. The results support the hypotheses.

  13. Development of an advanced undergraduate course in acoustics

    NASA Astrophysics Data System (ADS)

    Gee, Kent L.; Neilsen, Tracianne B.; Sommerfeldt, Scott D.

    2016-03-01

    Within many physics undergraduate programs, acoustics is given only a cursory treatment, usually within an introductory course. Because acoustics is a natural vehicle for students to develop intuition about wave phenomena, an advanced undergraduate acoustics course has been developed at Brigham Young University. Although it remains an elective course, enrollment has increased steadily since its inception. The course has been taken by students in physics, applied physics, physics teaching, and mechanical and electrical engineering. In addition to providing training for students motivated by interest in undergraduate research, internship, employment, and graduate schooling opportunities in acoustics, the course facilitates connections between various areas of physics. Explicit connections are made to mechanics, electricity and magnetism, thermodynamics, optics, quantum mechanics, and experimental and computational laboratory courses. Active learning is emphasized through Just-in-Time-Teaching and course structure. Homework exercises are both theoretical and practical and often require making and interpreting of graphs. For example, students may model traffic noise as a series of uncorrelated monopoles or examine highway barrier effectiveness using Fresnel diffraction techniques. Additionally, students participate in resumé-building measurements and learn to report their results in the form of technical memoranda. Course evaluations and post-graduation student surveys rate it among the most valuable undergraduate student courses offered.

  18. Project Kaleidoscope: Advancing What Works in Undergraduate STEM Education

    NASA Astrophysics Data System (ADS)

    Elrod, S.

    2011-12-01

    In 1989, Project Kaleidoscope (PKAL) published its first report, What Works: Building Natural Science Communities, on reforming undergraduate STEM (science, technology, engineering and mathematics) education. Since then, PKAL has grown into a national organization comprised of a diverse group of over 6500 STEM educators who are committed to advancing "what works." The PKAL mission is to be a national leader in catalyzing the efforts of people, institutions, organizations and networks to move from analysis to action in significantly improving undergraduate student learning and achievement in STEM (science, technology, engineering and mathematics). Specifically, PKAL's strategic goals are to: 1) Promote the development and wider use of evidence-based teaching, learning and assessment approaches, 2) Build individual and organizational capacity to lead change in STEM education, and 3) Engage the broader community of external stakeholders - professional and disciplinary societies, business and industry groups, accreditation organizations, educational associations, governmental agencies, philanthropic organizations - in achieving our mission. PKAL achieves these goals by serving as the nexus of an interconnected and multidisciplinary web of people, ideas, strategies, evidence and resources focused on systemic change in undergraduate STEM education. PKAL also provides resources on critical issues, such as teaching using pedagogies of engagement, and engages interested faculty, campuses and professional societies in national projects and programs focused on cutting edge issues in STEM education. One of these projects - Mobilizing Disciplinary Societies for a Sustainable Future - is engaging eleven disciplinary societies, including the National Association of Geoscience Teachers, in defining specific resources, faculty development programs and goals focused on promoting undergraduate STEM courses that: 1) provide more knowledge about real-world issues; 2) connect these real

  1. Tools for the advancement of undergraduate statistics education

    NASA Astrophysics Data System (ADS)

    Schaffner, Andrew Alan

    To keep pace with advances in applied statistics and to maintain literate consumers of quantitative analyses, statistics educators stress the need for change in the classroom (Cobb, 1992; Garfield, 1993, 1995; Moore, 1991a; Snee, 1993; Steinhorst and Keeler, 1995). These authors stress a more concept oriented undergraduate introductory statistics course which emphasizes true understanding over mechanical skills. Drawing on recent educational research, this dissertation attempts to realize this vision by developing tools and pedagogy to assist statistics instructors. This dissertation describes statistical facets, pieces of statistical understanding that are building blocks of knowledge, and discusses DIANA, a World-Wide Web tool for diagnosing facets. Further, I show how facets may be incorporated into course design through the development of benchmark lessons based on the principles of collaborative learning (diSessa and Minstrell, 1995; Cohen, 1994; Reynolds et al., 1995; Bruer, 1993; von Glasersfeld, 1991) and activity based courses (Jones, 1991; Yackel, Cobb and Wood, 1991). To support benchmark lessons and collaborative learning in large classes I describe Virtual Benchmark Instruction, benchmark lessons which take place on a structured hypertext bulletin board using the technology of the World-Wide Web. Finally, I present randomized experiments which suggest that these educational developments are effective in a university introductory statistics course.

    NASA Astrophysics Data System (ADS)

    Raftery, C. L.; Davis, H. B.; Peticolas, L. M.; Paglierani, R.

    2015-12-01

    The Space Sciences Laboratory at UC Berkeley launched an NSF-funded Research Experience for Undergraduates (REU) program in the summer of 2015. The "Advancing Space Sciences through Undergraduate Research Experiences" (ASSURE) program recruited heavily from local community colleges and universities, and provided a multi-tiered mentorship program for students in the fields of space science and engineering. The program was focussed on providing a supportive environment for 2nd and 3rd year undergraduates, many of whom were first generation and underrepresented students. This model provides three levels of mentorship support for the participating interns: 1) the primary research advisor provides academic and professional support. 2) The program coordinator, who meets with the interns multiple times per week, provides personal support and helps the interns to assimilate into the highly competitive environment of the research laboratory. 3) Returning undergraduate interns provided peer support and guidance to the new cohort of students. The impacts of this program on the first generation students and the research mentors, as well as the lessons learned will be discussed.

  5. Academic performance and student engagement in level 1 physics undergraduates

    NASA Astrophysics Data System (ADS)

    Casey, M. M.; McVitie, S.

    2009-09-01

    At the beginning of academic year 2007-08, staff in the Department of Physics and Astronomy at the University of Glasgow started to implement a number of substantial changes to the administration of the level 1 physics undergraduate class. The main aims were to improve the academic performance and progression statistics. With this in mind, a comprehensive system of learning support was introduced, the main remit being the provision of an improved personal contact and academic monitoring and support strategy for all students at level 1. The effects of low engagement with compulsory continuous assessment components had already been observed to have a significant effect on students sitting in the middle of the grade curve. Analysis of data from the 2007-08 class showed that even some nominally high-achieving students achieved lowered grades due to the effects of low engagement. Nonetheless, academic and other support measures put in place during 2007-08 played a part in raising the passrate for the level 1 physics class by approximately 8% as well as raising the progression rate by approximately 10%.

  17. Integrating recent advances in neuroscience into undergraduate neuroscience and physiology courses.

    PubMed

    Cleland, Corey L

    2002-12-01

    Neuroscience has enjoyed tremendous growth over the past 20 years, including a substantial increase in the number of neuroscience departments, programs, and courses at the undergraduate level. To meet the need of new neuroscience courses, there has also been growth in the number of introductory neuroscience textbooks designed for undergraduates. However, textbooks typically trail current knowledge by five to ten years, especially in neuroscience where our understanding is increasing rapidly. Consequently, it is often important to supplement neuroscience and physiology textbooks with information about recent findings in neuroscience. To design supplementary educational material, it is essential first to identify the educational objectives of the program and the characteristics of the learners, which can differ dramatically between undergraduate and graduate or professional students. Four principles that may serve the selection and design of supplementary material for undergraduate neuroscience and physiology courses are that (1) material must be interesting to the undergraduates, (2) material should reinforce previously learned concepts, (3) students must be adequately prepared, and (4) the teacher and student must have sufficient appropriate resources.

  19. NSF Support for Physics at the Undergraduate Level: A View from Inside

    NASA Astrophysics Data System (ADS)

    McBride, Duncan

    2015-03-01

    NSF has supported a wide range of projects in physics that involve undergraduate students. These projects include NSF research grants in which undergraduates participate; Research Experiences for Undergraduates (REU) centers and supplements; and education grants that range from upper-division labs that may include research, to curriculum development for upper- and lower-level courses and labs, to courses for non-majors, to Physics Education Research (PER). The NSF Divisions of Physics, Materials Research, and Astronomy provide most of the disciplinary research support, with some from other parts of NSF. I recently retired as the permanent physicist in NSF's Division of Undergraduate Education (DUE), which supports the education grants. I was responsible for a majority of DUE's physics grants and was involved with others overseen by a series of physics rotators. There I worked in programs entitled Instrumentation and Laboratory Improvement (ILI); Course and Curriculum Development (CCD); Course, Curriculum, and Laboratory Improvement (CCLI); Transforming Undergraduate STEM Education (TUES); and Improving Undergraduate STEM Education (IUSE). NSF support has enabled physics Principal Investigators to change and improve substantially the way physics is taught and the way students learn physics. The most important changes are increased undergraduate participation in physics research; more teaching using interactive engagement methods in classes; and growth of PER as a legitimate field of physics research as well as outcomes from PER that guide physics teaching. In turn these have led, along with other factors, to students who are better-prepared for graduate school and work, and to increases in the number of undergraduate physics majors. In addition, students in disciplines that physics directly supports, notably engineering and chemistry, and increasingly biology, are better and more broadly prepared to use their physics education in these fields. I will describe NSF

  10. Stereotyping at the undergraduate level revealed during interprofessional learning between future doctors and biomedical scientists.

    PubMed

    Lewitt, Moira S; Ehrenborg, Ewa; Scheja, Max; Brauner, Annelie

    2010-01-01

    Interprofessional education (IPE) involving undergraduate health professionals is expected to promote collaboration in their later careers. The role of IPE between doctors and biomedical scientists has not been explored at the undergraduate level. Our aim was to introduce IPE sessions for medical and biomedical students in order to identify the benefits and barriers to these groups learning together. Medical and biomedical students together discussed laboratory results, relevant literature, and ideas for developing new diagnostic tools. The programme was evaluated with questionnaires and interviews. While there was general support for the idea of IPE, medical and biomedical students responded differently. Biomedical students were more critical, wanted more explicit learning objectives and felt that their professional role was often misunderstood. The medical students were more enthusiastic but regarded the way the biomedical students communicated concerns about their perceived role as a barrier to effective interprofessional learning. We conclude that stereotyping, which can impede effective collaborations between doctors and biomedical scientists, is already present at the undergraduate level and may be a barrier to IPE. Effective learning opportunities should be supported at the curriculum level and be designed to specifically enable a broad appreciation of each other's future professional roles. PMID:20001546

    Given the rapidly changing demography of populations worldwide, dental professionals of the future need to be able to meet the challenge posed by the evolving landscape in health care needs. Leading institutions are now embedding teaching and learning in special care dentistry (SCD) within their curricula, to provide students with the knowledge, skills and attitudes to meet the oral health needs of vulnerable groups within their communities. The International Association for Disability and Oral Health (iADH) has initiated the development of undergraduate curriculum guidance in SCD through a consensus process. The curriculum in SCD is defined in statements of learning outcomes with many of the skills being transferable across the undergraduate course. This curriculum includes examples of teaching and assessment, designed to enhance critical thinking in relation to SCD and to promote positive attitudes towards disability and diversity. The learning outcomes are designed to be readily adapted to conform to the generic profiles and competencies, already identified in undergraduate frameworks by global educational associations, as well as meeting the requirements of professional regulatory bodies worldwide. Suggestions for teaching and learning are not intended to be prescriptive; rather, they act as a signpost to possible routes to student learning. Ideally, this will require that students have a sufficiently diverse patient case mix during their undergraduate studies, to achieve the required levels of confidence and competence by the time they graduate. Clinical care competencies in SCD emphasise the need for learners to broaden their theoretical knowledge and understanding through practical experience in providing care for people with special health care needs. It is crucial to the development of equitable dental services for all members of a community, that these learning outcomes are embedded into evolving curricula but most importantly, that they are evaluated and

    The Advanced Labs web resource collection is an effort to create a central, comprehensive information base for college/university faculty who teach upper-level undergraduate laboratories. The website is produced by the American Association of Physics Teachers (AAPT). It is a part of ComPADRE, the online collection of resources in physics and astronomy education, which itself is a part of the National Science Foundation-funded National Science Digital Library (NSDL). After a brief review of its history, we will discuss the current status of the website while describing the various types of resources available at the site and presenting examples of each. We will detail a step-by-step procedure for submitting resources to the website. The resource collection is designed to be a community effort and thus welcomes input and contributions from its users. We will also present plans, and will seek audience feedback, for additional website services and features. The constraints, roadblocks, and rewards of this project will also be addressed.

    2013-01-01

    Objective Stress among dental students can be a significant threat, resulting in physical and/or mental illness, and have a negative effect on students’ performance and the professional practice of dentistry. Stress can occur from different sources. The purpose of this study is to test whether the year of study has an effect on the stress levels of dental students. Method Our study consisted of a cross-sectional survey using a modified version of the Dental Environment Stress (DES) questionnaire. The questionnaires were filled out by male undergraduate dental students at King Saud University in Riyadh City during the 2010–2011 academic year (n = 214). Results The results show the most common sources of stress: examinations and completing clinical requirements. Moreover, in the five-year lecture-based traditional curriculum, the third year students reported the highest level of stress, whereas the first year reported the lowest level of stress. Conclusion Third year undergraduate dental students reported the highest level of stress. This stress could be reduced by reviewing and modifying the dental curriculum by allowing students to have contact with patients more gradually, starting from the first year, in addition to adding stress prevention and intervention programs in dental curricula.

  18. COMPRES Mineral Physics Educational Modules for Advanced Undergraduates and Graduate Students

    NASA Astrophysics Data System (ADS)

    2012-12-01

    The Consortium for Materials Properties Research in Earth Sciences (COMPRES) is a community-based consortium whose goal is to advance and facilitate experimental high pressure research in the Earth Sciences. An important aspect of this goal is sharing our knowledge with the next generation of researchers. To facilitate this, we have created a group of web-based educational modules on mineral physics topics. The modules reside in the On Cutting Edge, Teaching Mineralogy collection on the Science Education Resource Center (SERC) website. Although the modules are designed to function as part of a full semester course, each module can also stand alone. Potential users of the modules include mineral physics faculty teaching "bricks and mortar" classes at their own institutions, or in distance education setting, mineralogy teachers interested in including supplementary material in their mineralogy class, undergraduates doing independent study projects and graduate students and colleagues in other sub-disciplines who wish to brush up on a mineral physics topic. We used the modules to teach an on-line course entitled "Introduction to Mineral Physics" during the spring 2012 semester. More than 20 students and postdocs as well as 15 faculty and senior scientists participated in the course which met twice weekly as a webinar. Recordings of faculty lectures and student-led discussions of journal articles are now available upon request and edited versions of the lectures will be incorporated into the educational modules. Our experience in creating the modules and the course indicates that the use of 1) community-generated internet-based resources and 2) webinars to enable shared teaching between faculty at different universities, has the potential to both enrich graduate education and create efficiencies for university faculty.;

    1996-05-01

    This paper reports on an innovative teaching style for the instruction of advanced undergraduates in experimental science fundamentals. Working under the belief that a complete education includes both theoretical work and ``hands-on'' laboratory experience, a radio observatory has been created on top of the U. C. Berkeley Astronomy Department building. Class work with this observatory give students an understanding of: (1) components of a radio telescope system, (2) system operation and trouble-shooting, (3) observation strategies, (4) data collection and reduction, and (5) presentation and visualization of results. Our antenna consists of a two meter tall pyramidal horn optimized to observe the 21 cm atomic hydrogen transition. The receiver consists of a double-heterodyning system with a PC to sample and Fourier transform the signal and generate a power spectrum. System components were constructed by students with guidance from faculty members. Students using this system obtain power spectra representing the Doppler shifted HI line, as a function of galactic coordinate. Students derive results including basic galactic structure and rotation and mass curves. Further technical information is presented in the accompanying poster paper. Close contact between students and equipment is essential for successful comprehension of fundamental concepts. The system is constructed such that most components can be individually examined or assembled on a bench-top in a configuration the student wishes to explore. We believe that systems which perform real astronomy can be duplicated by other universities. The small scale of the antenna as well as the strength of the HI line require a small allocation of resources to implement an observation system. The ``hands-on'' approach compliments theoretical course work, in addition to providing practical experience for students who may not be inclined towards graduate school. Finally, this educational technique is exportable and

    Ocean Tracks is a Web-based interactive learning experience which allows users to explore the migrations of marine apex predators, and the way their behaviors relate to the physical and chemical environment surrounding them. Ocean Tracks provides access to data from the Tagging of Pelagic Predators (TOPP) program, NOAA's Global Drifter Program, and Earth-orbiting satellites via the Ocean Tracks interactive map interface; customized data analysis tools; multimedia supports; along with laboratory modules customized for undergraduate student use. It is part of a broader portfolio of projects comprising the Oceans of Data Institute, dedicated to transforming education to prepare citizens for a data-intensive world. Although originally developed for use in high school science classrooms, the Ocean Tracks interface and associated curriculum has generated interest among instructors at the undergraduate level, who wanted to engage their students in hands-on work with real scientific datasets. In 2014, EDC and the Scripps Institution of Oceanography received funding from NSF's IUSE program for Ocean Tracks: College Edition, to investigate how a learning model that includes a data interface, set of analysis tools, and curricula can be used to motivate students to learn and do science with real data; bringing opportunities to engage broad student populations, including both in-classroom and remote, on-line participants, in scientific practice. Phase 1, completed in the summer of 2015, was a needs assessment, consisting of a survey and interviews with students in oceanography classes at the Scripps Institution of Oceanography and Palomar Community College; a document review of course syllabi and primary textbooks used in current college marine science courses across the country; and interviews and a national survey of marine science faculty. We will present the results of this work, and will discuss new curriculum materials that are being classroom tested in the fall of 2015.

  3. An investigation of communication patterns and strategies between international teaching assistants and undergraduate students in university-level science labs

    NASA Astrophysics Data System (ADS)

    Gourlay, Barbara Elas

    This research project investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. During the fall semester, introductory-level chemistry lab sections of three experienced non-native speaking teaching assistants and their undergraduate students were observed. Digital audio and video recordings documented fifteen hours of lab communication, focusing on the activities and interactions in the first hour of the chemistry laboratory sessions. In follow-up one-on-one semi-structured interviews, the participants (undergraduates, teaching assistants, and faculty member) reviewed interactions and responded to a 10-item, 7-point Likert-scaled interview. Interactions were classified into success categories based on participants' opinions. Quantitative and qualitative data from the observations and interviews guided the analysis of the laboratory interactions, which examined patterns of conversational listening. Analysis of laboratory communication reveals that undergraduates initiated nearly two-thirds of laboratory communication, with three-fourths of interactions less than 30 seconds in duration. Issues of gender and topics of interaction activity were also explored. Interview data identified that successful undergraduate-teaching assistant communication in interactive science labs depends on teaching assistant listening comprehension skills to interpret and respond successfully to undergraduate questions. Successful communication in the chemistry lab depended on the coordination of visual and verbal sources of information. Teaching assistant responses that included explanations and elaborations were also seen as positive features in the communicative exchanges. Interaction analysis focusing on the listening comprehension demands placed on international teaching assistants revealed that undergraduate-initiated questions often employ deixis (exophoric reference), requiring teaching assistants to

    2015-01-01

    Synthetic biology offers an ideal opportunity to promote undergraduate laboratory courses with research-style projects, immersing students in an inquiry-based program that enhances the experience of the scientific process. We designed a semester-long, project-based laboratory curriculum using synthetic biology principles to develop a novel sensory device. Students develop subject matter knowledge of molecular genetics and practical skills relevant to molecular biology, recombinant DNA techniques, and information literacy. During the spring semesters of 2014 and 2015, the Synthetic Biology Laboratory Project was delivered to sophomore genetics courses. Using a cloning strategy based on standardized BioBrick genetic “parts,” students construct a “reporter plasmid” expressing a reporter gene (GFP) controlled by a hybrid promoter regulated by the lac-repressor protein (lacI). In combination with a “sensor plasmid,” the production of the reporter phenotype is inhibited in the presence of a target environmental agent, arabinose. When arabinose is absent, constitutive GFP expression makes cells glow green. But the presence of arabinose activates a second promoter (pBAD) to produce a lac-repressor protein that will inhibit GFP production. Student learning was assessed relative to five learning objectives, using a student survey administered at the beginning (pre-survey) and end (post-survey) of the course, and an additional 15 open-ended questions from five graded Progress Report assignments collected throughout the course. Students demonstrated significant learning gains (p < 0.05) for all learning outcomes. Ninety percent of students indicated that the Synthetic Biology Laboratory Project enhanced their understanding of molecular genetics. The laboratory project is highly adaptable for both introductory and advanced courses. PMID:26753032

    PubMed

    Hurd, Daryl D

    2008-01-01

    The skill set required of biomedical researchers continues to grow and evolve as biology matures as a natural science. Science necessitates creative yet critical thinking, persuasive communication skills, purposeful use of time, and adeptness at the laboratory bench. Teaching these skills can be effectively accomplished in an inquiry-based, active-learning environment at a primarily undergraduate institution. Cell Biology Techniques, an upper-level cell biology laboratory course at St. John Fisher College, features two independent projects that take advantage of the biology of the nematode Caenorhabditis elegans, a premier yet simple model organism. First, students perform a miniature epigenetic screen for novel phenotypes using RNA interference. The results of this screen combined with literature research direct students toward a singe gene that they attempt to subclone in the second project. The biology of the chosen gene/protein also becomes an individualized focal point with respect to the content of the laboratory. Progress toward course goals is evaluated using written, oral, and group-produced assignments, including a concept map. Pre- and postassessment indicates a significant increase in the understanding of broad concepts in cell biological research. PMID:18519612

    The objectives of this quantitative survey research were (1) to establish the level of scientific reasoning (SR) skills among science, mathematics and engineering (SME) undergraduates in Malaysian Institute of Higher Learning (IHL); (b) to identify the types of instructional methods in teaching SME at universities; and (c) to map instructional methods employed to the level of SR skills among the undergraduates. There were six universities according to zone involved in this study using the stratification random sampling technique. For each university, the faculties that involved were faculties which have degree students in science, mathematics and engineering programme. A total of 975 students were participated in this study. There were two instruments used in this study namely, the Lawson Scientific Reasoning Skills Test and the Lecturers' Teaching Style Survey. The descriptive statistics and the inferential statistics such as mean, t-test and Pearson correlation were used to analyze the data. Findings of the study showed that most students had concrete level of scientific reasoning skills where the overall mean was 3.23. The expert and delegator were dominant lecturers' teaching styles according to students' perception. In addition, there was no correlation between lecturers' teaching style and the level of scientific reasoning skills. Thus, this study cannot map the dominant lecturers' teaching style to the level of scientific reasoning skills of Science, Mathematics and Engineering undergraduates in Malaysian Public Institute of Higher Learning. Nevertheless, this study gave some indications that the expert and delegator teaching styles were not contributed to the development of students' scientific reasoning skills. This study can be used as a baseline for Science, Mathematics and Engineering undergraduates' level of scientific reasoning skills in Malaysian Public Institute of Higher Learning. Overall, this study also opens an endless source of other

    Objectives Unrelieved pain is a substantial public health concern necessitating improvements in medical education. The Advancing the Provision of Pain Education and Learning (APPEAL) study aimed to determine current levels and methods of undergraduate pain medicine education in Europe. Design and methods Using a cross-sectional design, publicly available curriculum information was sought from all medical schools in 15 representative European countries in 2012–2013. Descriptive analyses were performed on: the provision of pain teaching in dedicated pain modules, other modules or within the broader curriculum; whether pain teaching was compulsory or elective; the number of hours/credits spent teaching pain; pain topics; and teaching and assessment methods. Results Curriculum elements were publicly available from 242 of 249 identified schools (97%). In 55% (133/242) of schools, pain was taught only within compulsory non-pain-specific modules. The next most common approaches were for pain teaching to be provided wholly or in part via a dedicated pain module (74/242; 31%) or via a vertical or integrated approach to teaching through the broader curriculum, rather than within any specific module (17/242; 7%). The curricula of 17/242 schools (7%) showed no evidence of any pain teaching. Dedicated pain modules were most common in France (27/31 schools; 87%). Excluding France, only 22% (47/211 schools) provided a dedicated pain module and in only 9% (18/211) was this compulsory. Overall, the median number of hours spent teaching pain was 12.0 (range 4–56.0 h; IQR: 12.0) for compulsory dedicated pain modules and 9.0 (range 1.0–60.0 h; IQR: 10.5) for other compulsory (non-pain specific) modules. Pain medicine was principally taught in classrooms and assessed by conventional examinations. There was substantial international variation throughout. Conclusions Documented pain teaching in many European medical schools falls far short of what might be expected given the

    Philipp, Stephanie B.

    Increasing retention of students in science, technology, engineering, or mathematics (STEM) programs of study is a priority for many colleges and universities. This study examines an undergraduate teaching assistant (UTA) program implemented in a general chemistry course for STEM majors to provide peer learning assistance to entrylevel students. This study measured the content knowledge growth of UTAs compared to traditional graduate teaching assistants (GTAs) over the semester, and described the development of peer learning assistance skills of the UTAs as an outcome of semesterlong training and support from both science education and STEM faculty. Impact of the UTA program on final exam grades, persistence of students to enroll in the next chemistry course required by their intended major, and STEM identity of students were estimated. The study sample comprised 284 students in 14 general chemistry recitation sections led by six UTAs and 310 students in 15 general chemistry recitation sections led by three traditional GTAs for comparison. Results suggested that both UTAs and GTAs made significant learning gains in general chemistry content knowledge, and there was no significant difference in content knowledge between UTA and GTA groups. Student evaluations, researcher observations, and chemistry faculty comments confirm UTAs were using the learning strategies discussed in the semester-long training program. UTA-led students rated their TAs significantly higher in teaching quality and student care and encouragement, which correlated with stronger STEM recognition by those students. The results of hierarchical linear model (HLM) analysis showed little variance in final exam grades explained by section-level variables; most variance was explained by student-level variables: mathematics ACT score, college GPA, and intention to enroll in the next general chemistry course. Students having higher college GPAs were helped more by having a UTA. Results from logistic

  19. Incorporating Inquiry into Upper-Level Undergraduate Homework Assignments: The Mini-Journal

    NASA Astrophysics Data System (ADS)

    Whittington, Alan; Speck, Angela; Witzig, Stephen; Abell, Sandra

    2010-05-01

    The US National Science Education Standards (2000) state that science should be taught through inquiry. The five essential features of classroom inquiry are that the leaner (i) engages in scientifically oriented questions, (ii) gives priority to evidence in responding to questions, (iii) formulates explanations from evidence, (iv) connects explanations to scientific knowledge, and (v) communicates and justifies explanations. One difficulty in achieving this vision at the university level lies in the common perception that inquiry be fully open and unstructured, and that its implementation will be impractical due to time and material constraints. In an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," faculty developed new inquiry-based laboratory curriculum materials using a "mini-journal" approach, which is designed as an alternative to the cookbook laboratory and represents the way that scientists do science. Here we adapt this approach to a homework assignment in an upper-level Planetary Science class, and show that inquiry is achievable in this setting. Traditional homeworks in this class consisted of problem sets requiring algebraic manipulation, computation, and in most cases an appraisal of the result Longer questions are broken down into chunks worth 1 to 4 points. In contrast, the mini-journal is a short article that is modeled in the way that scientists do and report science. It includes a title, abstract, introduction (with clear statement of the problem to be tackled), a description of the methods, results (presented as both tables and graphs), a discussion (with suggestions for future work) and a list of cited work. Students devise their research questions and hypothesis from the paper based on a logical next step in the investigation. Guiding questions in the discussion can assist the students ("it would be interesting to evaluate the effect of ..."). Students submit their own minijournal, using the same journal

    1974-01-01

    A study was conducted to determine the promising propulsion systems for advanced supersonic transport application, and to identify the critical propulsion technology requirements. It is shown that noise constraints have a major effect on the selection of the various engine types and cycle parameters. Several promising advanced propulsion systems were identified which show the potential of achieving lower levels of sideline jet noise than the first generation supersonic transport systems. The non-afterburning turbojet engine, utilizing a very high level of jet suppression, shows the potential to achieve FAR 36 noise level. The duct-heating turbofan with a low level of jet suppression is the most attractive engine for noise levels from FAR 36 to FAR 36 minus 5 EPNdb, and some series/parallel variable cycle engines show the potential of achieving noise levels down to FAR 36 minus 10 EPNdb with moderate additional penalty. The study also shows that an advanced supersonic commercial transport would benefit appreciably from advanced propulsion technology. The critical propulsion technology needed for a viable supersonic propulsion system, and the required specific propulsion technology programs are outlined.

    2015-03-01

    Cyanobacteria have been shown to be capable of producing a variety of advanced biofuels; however, product yields remain well below those necessary for large scale production. New genetic tools and high throughput metabolic engineering techniques are needed to optimize cyanobacterial metabolisms for enhanced biofuel production. Towards this goal, this project advances the development of a multiple promoter replacement technique for systems-level optimization of gene expression in a model cyanobacterial host: Synechococcus sp. PCC 7002. To realize this multiple-target approach, key capabilities were developed, including a high throughput detection method for advanced biofuels, enhanced transformation efficiency, and genetic tools for Synechococcus sp. PCC 7002. Moreover, several additional obstacles were identified for realization of this multiple promoter replacement technique. The techniques and tools developed in this project will help to enable future efforts in the advancement of cyanobacterial biofuels.

    The Technology Readiness Level (TRL) process is used to quantitatively assess the maturity of a given technology. The TRL process has been developed and successfully used by the Department of Defense (DOD) for development and deployment of new technology and systems for defense applications. In addition, NASA has also successfully used the TRL process to develop and deploy new systems for space applications. Advanced nuclear fuels and materials development is a critical technology needed for closing the nuclear fuel cycle. Because the deployment of a new nuclear fuel forms requires a lengthy and expensive research, development, and demonstration program, applying the TRL concept to the advanced fuel development program is very useful as a management and tracking tool. This report provides definition of the technology readiness level assessment process as defined for use in assessing nuclear fuel technology development for the Advanced Fuel Campaign (AFC).

    2009-04-01

    Physics is an experimental science. In other words, all physical laws are based on experimentally observable phenomena. Therefore, it is important that all physics students have an understanding of the limitations of certain experimental techniques and the associated errors associated with a particular measurement. The students in the Advanced Laboratory class at Texas State perform three detailed laboratory experiments during the semester and give an oral presentation at the end of the semester on a scientific topic of their choosing. The laboratory reports are written in the format of a ``Physical Review'' journal article. The experiments are chosen to give the students a detailed background in error analysis and experimental design. For instance, the first experiment performed in the spring 2009 semester is entitled Measurement of the local acceleration due to gravity in the RFM Technology and Physics Building. The goal of this experiment is to design and construct an instrument that is to be used to measure the local gravitational field in the Physics Building to an accuracy of ±0.005 m/s^2. In addition, at least one of the experiments chosen each semester involves the use of the research facilities within the physics department (e.g., microfabrication clean room, surface science lab, thin films lab, etc.), which gives the students experience working in a research environment.

    2013-01-01

    Objectives Evaluate the way the topics for the study of pain mechanisms in general, and Orofacial Pain (OFP) and temporomandibular disorders (TMDs) more specifically, are addressed in undergraduate courses curricula, and also to verify the existence of specialist OFP/TMD teachers in Brazilian dental schools. Methods Between July 2010 and January 2011, course Coordinators/Directors of all dental schools duly registered at the Ministry of Education were invited to answer a questionnaire on topics related to OFP/TMD teaching in their institutions. Results Fifty-three dental schools representatives answered the questionnaire. The study of pain mechanisms was found to cover an average of less than 10% of the courses' total time. Pharmacology, Endodontics and Physiology were identified as the departments usually responsible for addressing pain mechanisms in dental courses. Psychosocial aspects were found to occupy a very small proportion in the syllabi, while most of the content referred to biological or somatic aspects. OFP/TMD is addressed by a specific department in only 28.4% of the participating dental schools, while in most cases (46.3%), OFP/TMD is under the responsibility of the Prosthodontics department. Only 38.5% of respondents indicated that they had a specialist OFP/TMD teacher in their Schools. Conclusion Among the Brazilian dental schools participating in the study, the teaching of OFP/TMD was found to be insufficient, segmented or with an extremely restricted focus. This initial assessment indicates that Curricular Guidelines for the study of OFP/TMD at undergraduate dental schools should be developed and implemented to facilitate their appropriate inclusion into the curricula and in specific pedagogical projects.

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

    2014-12-01

    Utilizing advances in hydrologic research and technology, learning modules can be developed to deliver visual, case-based, data and simulation driven educational experiences. This paper focuses on the development of web modules based on case studies in Coastal Louisiana, one of three ecosystems that comprise an ongoing hydrology education online system called HydroViz. The Chenier Plain ecosystem in Coastal Louisiana provides an abundance of concepts and scenarios appropriate for use in many undergraduate water resource and hydrology curricula. The modules rely on a set of hydrologic data collected within the Chenier Plain along with inputs and outputs of eco-hydrology and vegetation-change simulation models that were developed to analyze different restoration and protection projects within the 2012 Louisiana Costal Master Plan. The modules begin by investigating the basic features of the basin and it hydrologic characteristics. The eco-hydrology model is then introduced along with its governing equations, numerical solution scheme and how it represents the study domain. Concepts on water budget in a coastal basin are then introduced using the simulation model inputs, outputs and boundary conditions. The complex relationships between salinity, water level and vegetation changes are then investigated through the use of the simulation models and associated field data. Other student activities focus on using the simulation models to evaluate tradeoffs and impacts of actual restoration and protection projects that were proposed as part of 2012 Louisiana Master Plan. The hands-on learning activities stimulate student learning of hydrologic and water management concepts by providing real-world context and opportunity to build fundamental knowledge as well as practical skills. The modules are delivered through a carefully designed user interface using open source and free technologies which enable wide dissemination and encourage adaptation by others.

    Miller-Clemente, R; Mendez-Perez, L

    2015-06-15

    Purpose: To contribute to the professional profile of future medical physicists, technologists and physicians, and implement an adaptable educational strategy at both undergraduate and postgraduate levels. Methods: The Medical Physics Block of Electives (MPBE) designed was adapted to the Program of B.S. in Physics. The conferences and practical activities were developed with participatory methods, with interdisciplinary collaboration from research institutions and hospitals engaged on projects of Research, Development and Innovation (RDI). The scientific education was implemented by means of critical analysis of scientific papers and seminars where students debated on solutions for real research problems faced by medical physicists. This approach included courses for graduates not associated to educational programs of Medical Physics (MP). Results: The implementation of the MPBE began in September 2014, with the electives of Radiation MP and Introduction to Nuclear Magnetic Resonance. The students of second year received an Introduction to MP. This initiative was validated by the departmental Methodological Workshop, which promoted the full implementation of the MPBE. Both postgraduated and undergraduate trainees participated in practices with our DICOM viewer system, a local prototype for photoplethysmography and a home-made interface for ROC analysis, built with MATLAB. All these tools were designed and constructed in previous RDI projects. The collaborative supervision of University’s researchers with clinical medical physicists will allow to overcome the limitations of residency in hospitals, to reduce the workload for clinical supervisors and develop appropriate educational activities. Conclusion: We demonstrated the feasibility of adaptable educational strategies, considering available resources. This provides an innovative way for prospective medical physicists, technologists and radiation oncologists. This strategy can be implemented in several regions

    The Space Sciences Laboratory (SSL) has a long history of undergraduates working within the various research groups that range from theoretical astrophysics through to mechanical engineering. This year, we have established for the first time, a formal summer program for the undergraduate students, focusing on students traditionally underserved in Geosciences. This program, called the Advancing Space Science through Undergraduate Research Experiences program brings best-practiced methods to the development of a cohort, academic achievement, and research methodologies to the summer interns, with emphasis on the needs of underrepresented students who have not been exposed to a research environment before. In addition, specific care was given when recruiting for the program. Community College students recommend to us by faculty partners within the Colleges were recruited in order to provide them with hands on experience in a laboratory setting that they would not otherwise have had. In addition, we selected a number of pre- and in-service teachers from the STEM Teacher and Researcher Program (STAR) program. The combination of these two demographics of students has provided a unique and supportive environment for all involved.

    Community interventions are complex social processes that need to move beyond single interventions and outcomes at individual levels of short-term change. A scientific paradigm is emerging that supports collaborative, multilevel, culturally situated community interventions aimed at creating sustainable community-level impact. This paradigm is rooted in a deep history of ecological and collaborative thinking across public health, psychology, anthropology, and other fields of social science. The new paradigm makes a number of primary assertions that affect conceptualization of health issues, intervention design, and intervention evaluation. To elaborate the paradigm and advance the science of community intervention, we offer suggestions for promoting a scientific agenda, developing collaborations among professionals and communities, and examining the culture of science.

    At present, in computer vision, the approach based on modeling the biological vision mechanisms is extensively developed. However, up to now, real world image processing has no effective solution in frameworks of both biologically inspired and conventional approaches. Evidently, new algorithms and system architectures based on advanced biological motivation should be developed for solution of computational problems related to this visual task. Basic problems that should be solved for creation of effective artificial visual system to process real world imags are a search for new algorithms of low-level image processing that, in a great extent, determine system performance. In the present paper, the result of psychophysical experiments and several advanced biologically motivated algorithms for low-level processing are presented. These algorithms are based on local space-variant filter, context encoding visual information presented in the center of input window, and automatic detection of perceptually important image fragments. The core of latter algorithm are using local feature conjunctions such as noncolinear oriented segment and composite feature map formation. Developed algorithms were integrated into foveal active vision model, the MARR. It is supposed that proposed algorithms may significantly improve model performance while real world image processing during memorizing, search, and recognition.

    Objective: The aim of this study is to determine differences of levels of empathy among undergraduates in each year of their four-year programs of physiotherapy. Methods: During the 2014-2015 academic school year, 381 physiotherapy students were enlisted from two universities in Istanbul, one a foundation and the other a government university. The Turkish version of the Jefferson Scale of Physician Empathy was administered. Students were asked to indicate interest in particular physiotherapy specialties as well as their region of origin in Turkey. The Kruskal-Wallis analysis was used to determine differences among the four study years, and also to measure relationships between specialty interest, home-region, and empathy scores of the students. Empathy scores were also compared according to gender. Results: The difference of empathy scores between the students of the two universities was borderline significant (p=0.057). Empathy scores in both universities increased to a significant degree after school entrance and decreased in the final year. Levels of empathy did not change according to gender, specialty interest, or home-region (p=0.722, 0.524, and 0.309, respectively). Conclusions: This study points to the need for physiotherapy curricula that would enhance empathy and give students practice in exhibiting this valuable attribute. Additional studies are needed that would include larger study populations and track the same students year by year as to how and why their empathy levels change during their training. PMID:27022351

    Spatial visualization is an essential skill in the STEM disciplines, including the geosciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may be unable to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. As a group of geoscience faculty members and cognitive psychologists, we have developed a set of curricular materials for Mineralogy, Sedimentology & Stratigraphy, and Structural Geology courses. These materials are designed to improve students' spatial skills, and in particular to improve students' abilities to reason about spatially complex 3D geological concepts and problems. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate STEM education by removing one significant barrier to success in the STEM disciplines. The curricular materials we have developed are based on several promising teaching strategies that have emerged from cognitive science research on spatial thinking. These strategies include predictive sketching, making visual comparisons, gesturing, and the use of analogy. We have conducted a three-year study of the efficacy of these materials in strengthening the spatial skills of students in upper-level geoscience courses at three universities. Our methodology relies on a pre- and post-test study design, with several tests of spatial thinking skills administered at the beginning and end of each semester. In 2011-2012, we used a "business as usual" approach to gather baseline data, measuring how much students' spatial thinking skills improved in response to the existing curricula. In the two subsequent years we have incorporated our new curricular materials, which can be found on the project website: http://serc.carleton.edu/spatialworkbook/activities.html Structural Geology

    Milestone Description - Advanced Initiation Systems Detonator Design and Prototype. Milestone Grading Criteria - Design new generation chip slapper detonator and manufacture a prototype using advanced manufacturing processes, such as all-dry chip metallization and solvent-less flyer coatings. The advanced processes have been developed for manufacturing detonators with high material compatibility and reliability to support future LEPs, e.g. the B61, and new weapons systems. Perform velocimetry measurements to determine slapper velocity as a function of flight distance. A prototype detonator assembly and stripline was designed for low-energy chip slappers. Pictures of the prototype detonator and stripline are shown. All-dry manufacturing processes were used to address compatibility issues. KCP metallized the chips in a physical vapor deposition system through precision-aligned shadow masks. LLNL deposited a solvent-less polyimide flyer with a processes called SLIP, which stands for solvent-less vapor deposition followed by in-situ polymerization. LANL manufactured the high-surface-area (HSA) high explosive (HE) pellets. Test fires of two chip slapper designs, radius and bowtie, were performed at LLNL in the High Explosives Application Facility (HEAF). Test fires with HE were conducted to establish the threshold firing voltages. pictures of the chip slappers before and after test fires are shown. Velocimetry tests were then performed to obtain slapper velocities at or above the threshold firing voltages. Figure 5 shows the slapper velocity as a function of distance and time at the threshold voltage, for both radius and bowtie bridge designs. Both designs were successful at initiating the HE at low energy levels. Summary of Accomplishments are: (1) All-dry process for chip manufacture developed; (2) Solventless process for slapper materials developed; (3) High-surface area explosive pellets developed; (4) High performance chip slappers developed; (5) Low-energy chip

    Purpose This research examines the extent and nature of empathy among emergency health (paramedic), nursing, and midwifery students at one Australian university and investigates the longitudinal changes in empathy levels across the course of study. Methods First-, second-, and third-year students at Monash University completed the Jefferson Scale of Empathy–Health Professional (JSE-HP) in 2008, 2009, and 2010, and the resulting mean empathy scores were analyzed by course, year of course, year of study, age, and sex. Results Midwifery students were found to have higher empathy levels than nursing and emergency health students. Second- and third-year students scored higher than their counterparts in the first year. Empathy levels dipped in 2009 and rose in 2010. Students aged 26–30 years and 31–35 years recorded higher scores than their younger colleagues, and female students were found to be more empathic than their male counterparts. Conclusion The finding that empathy levels are relatively stable over the term of study contributes to the understanding of how empathy evolves over the course of study and offers insights into the importance of incorporating and promoting empathy in health care curricula.

    PURPOSE The use of joint leveling procedures to treat Kienbock’s disease has been limited by the degree of disease advancement. This study was designed to compare clinical and radiographic outcomes of wrists with more advanced Kienbock’s disease (stage IIIB) to wrists with less advanced disease (stage II/IIIA) following radius shortening osteotomy. METHODS This retrospective study enrolled 31 adult wrists (30 patients, mean age 39 years), treated by radius shortening osteotomy between two institutions for either stage IIIB (n=14) or stage II/IIIA (n=17) disease. Evaluation was carried out at a mean of 74 months (IIIB, 77 months; II/IIIA, 72 months). Radiographic assessment determined disease progression. Clinical outcomes were determined by validated patient-based and objective measures. RESULTS Patient-based outcome ratings of wrists treated for stage IIIB were similar to those with stage II/IIIA [QuickDASH (15 vs 12:p=.63), MMWS (84 vs 87:p=.59), VAS pain (1.2 vs 1.7:p=.45), VAS function (2.6 vs 2.1:p=.59)]. The average flexion/extension arc was 102° for wrists with stage IIIB and 106° for wrists with stage II/IIIA Kienbock’s (p=.70). Grip strength was 77% of the opposite side for stage IIIB wrists versus 85% for stage II/IIIA (p=.25). Postoperative carpal height ratio and radioscaphoid angle were worse (p<.05) for wrists treated for stage IIIB (0.46:65°) than stage II/IIIA (0.53:53°) disease. Radiographic disease progression occurred in 7 wrists (6 stage II/IIIA: 1 stage IIIB). The one stage IIIB wrist that progressed underwent wrist arthrodesis. CONCLUSIONS In this limited series, clinical outcomes of radius shortening using validated, patient-based assessment instruments and objective measures failed to demonstrate predicted “clinically relevant” differences between stage II/IIIA and IIIB Kienbock’s. Provided the high percentage successful clinical outcomes in this case series of 14 stage IIIB wrists, we believe that static carpal malalignment

    Ludrick, Brad Burton

    Purpose of the study. This study was designed to measure the effects of CD-ROM textbook integration on student achievement and student cognition-level-attainment for undergraduate general biology students. Four sections of general biology were selected as the study group. Two sections served as the experimental group receiving CD-ROM textbook integration. The remaining two sections served as the control group, and were taught biological content utilizing a traditional textbook. Procedure. This study employed a pre-experimental research design, static group comparison (Ary, Jacobs, & Razavieh, 1996: 331), to determine if a CD-ROM textbook had significant effects on student cognition-level-attainment and content achievement of undergraduate biology students. The study was conducted during the 2001 spring semester at Southeastern Oklahoma State University. The duration of the treatment was approximately sixteen weeks. Four sections of general biology (N = 101) were selected as the study group. Two of the four sections of general biology (n = 48) were randomly selected by the researcher via coin toss to serve as the experimental group, Group A, and were taught biological content utilizing a CD-ROM Textbook. The remaining two sections of general biology (n = 53) served as the control group, Group B, and were taught biological content utilizing a traditional textbook. Various statistical tests were used in analysis of the data. The ten null hypotheses were tested at the .05 level of significance. The Statistical Package for the Social Sciences program (SPSS), version 9.0 (SPSS, 1999), was used to process the data. Results. The results determined by this study were the overall effects of the CD-ROM textbook did not significantly differ from the effects of the traditional textbook on student content achievement and cognition-level-attainment. Conclusions. The utilization of CD-ROM textbook instruction is not superior at improving student achievement of biology content, as

    Atrial fibrillation is a common heart arrhythmia, and can be effectively treated with ablation. Ablation planning requires 3D models of the patient's left atrium (LA) and/or right atrium (RA), therefore an automatic segmentation procedure to retrieve these models is desirable. In this study, we investigate the use of advanced level set segmentation approaches to automatically segment RA in magnetic resonance angiographic (MRA) volume images. Low contrast to noise ratio makes the boundary between the RA and the nearby structures nearly indistinguishable. Therefore, pure data driven segmentation approaches such as watershed and ChanVese methods are bound to fail. Incorporating training shapes through PCA modeling to constrain the segmentation is one popular solution, and is also used in our segmentation framework. The shape parameters from PCA are optimized with a global histogram based energy model. However, since the shape parameters span a much smaller space, it can not capture fine details of the shape. Therefore, we employ a second refinement step after the shape based segmentation stage, which follows closely the recent work of localized appearance model based techniques. The local appearance model is established through a robust point tracking mechanism and is learned through landmarks embedded on the surface of training shapes. The key contribution of our work is the combination of a statistical shape prior and a localized appearance prior for level set segmentation of the right atrium from MRA. We test this two step segmentation framework on porcine RA to verify the algorithm.

    2010-01-01

    Introduction: Since there have been a number of empirical observations that may lead to the conclusion of an increasing rate of risk behaviors in Romanian students, such as aggression, over–competitive conduct and lack of collaboration, immorality, peer pressure and even an increasing rate of suicide, and suicide attempts, we have undergone a study to indentify if there is a high rate of risk type personality patterns that may lead to these deportments. Material and methods: We have selected a total number of 500 students from the three largest universities in Bucharest, Romania–‘Carol Davila’ University of Medicine and Pharmacy (UMF), Bucharest Polytechnics University (UPB), and the Bucharest Academy of Economical Studies (ASE). All subjects received a questionnaire containing four diagnostic tools and several demographics questions. We have chosen the Twenty Item Toronto Alexithymia Scale (TAS20), the Jenkins Activity Survey (JAS–13) and the Anger–In Questionnaire for type C personality pattern. We have also added the Columbia stress analysis questionnaire for the evaluation of stress levels and coping capacity at the moment the subjects were interviewed. Results: Columbia stress survey results confirm that there is a high stress level among students of all universities, but a more detailed stratification by university, gender and analyzed factor shows a very high F factor and T factor positive responses. Alexithymia, Type A and Type C personality patterns show a much higher prevalence than the general population, especially in medical students. We have found higher frequencies in men for all of the three studied parameters. Conclusions: Approaching alexithymia and type A behavior both by cognitive methods and by assessing and addressing consequential risk factors should become an issue among universities. PMID:20968210

    2007-12-01

    Integrating student-conducted research into the curriculum can provide students with many educational benefits. Documented benefits include, among others, increased communication skills, the ability to work as part of a research team, and enhanced self-confidence in individual problem-solving skills (e.g., Kardash, J. Ed. Psych., 2000; Seymour, et al., Science Education, 2004). As part of a larger departmental goal of integrating student- conducted research into all levels of the Pomona College Geology Department curriculum (e.g., Reinen, et al., CUR-Q, 2006), I have recently developed an intermediate-level Neotectonics course with a strong component of inquiry-based learning. This course was offered for the first time during the spring semester 2007, and will continue to be offered each year. In a series of guided inquiries throughout the course, students investigate recent seismicity and tectonic geomorphology in Southern California. With each subsequent assignment, student contributions to the research direction increases (e.g., data used, area studied, question addressed, methods used), culminating in team proposals and research projects investigating specific student-generated questions of regional tectonics. Students collect data for these investigations from several sources: (1) databases available online (e.g., IRIS, Harvard earthquake catalog), (2) desktop experiments (e.g., the "earthquake machine"), (3) topographic maps, and (4) field observations. The objective of this paper is to present initial results from this teaching experiment and examples of the projects which have been executed, including the preparation students received to be able to use the available data. Discussion and suggestions (particularly about effective means of conducting a rigorous long-term assessment) are strongly encouraged.

    Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed over some 15 years as part of a large national Australian study pertaining to the area of undergraduate laboratories-Advancing Science by Enhancing Learning in the Laboratory. This paper reports on the development of the survey instrument and the evaluation of the survey using student responses to experiments from different institutions in Australia, New Zealand and the USA. A total of 3153 student responses have been analysed using factor analysis. Three factors, motivation, assessment and resources, have been identified as contributing to improved student attitudes to laboratory activities. A central focus of the survey is to provide feedback to practitioners to iteratively improve experiments. Implications for practitioners and researchers are also discussed.

    2015-08-01

    Continued changes to healthcare delivery in the UK, and an increasing focus on patient safety and quality improvement, require a radical rethink on how we enable graduates to begin work in challenging, complex environments. Professional regulatory bodies now require undergraduate medical schools to implement an 'assistantship' period in the final year of study, where senior medical students 'shadow' the work of junior doctors, with an expectation that they will be better 'prepared' for work. However, there is little guidance about what an 'assistantship' entails and the current emphasis on preparedness of students arguably underplays the importance of contextualised learning within the workplace environment. This paper will describe a modified Development Work Research (DWR) (Engeström in Developmental work research: activity theory in practice. Lehmanns Media, Berlin, 2005) approach to organisational change, enabling academic, clinical and administrative partners to develop assistantship placements in different hospitals. Our findings indicate that a modified DWR approach can reveal factors indicating organisational readiness to support change within a locally contextualised framework. The process has significant practical applications across a range of healthcare disciplines, as all professions seek to engage with the challenge of enabling successful transitions of graduates to the workplace.

    Bi-Level Integrated System Synthesis (BLISS) is a method for optimization of an engineering system, e.g., an aerospace vehicle. BLISS consists of optimizations at the subsystem (module) and system levels to divide the overall large optimization task into sets of smaller ones that can be executed concurrently. In the initial version of BLISS that was introduced and documented in previous publications, analysis in the modules was kept at the early conceptual design level. This paper reports on the next step in the BLISS development in which the fidelity of the aerodynamic drag and structural stress and displacement analyses were upgraded while the method's satisfactory convergence rate was retained.

    2014-04-01

    In developing countries, the number of experts and students in geo-informatics domain are very limited compared to experts and students of sciences that could benefit from geo-informatics. In this research, we study the possibility of providing an online education system for teaching geo-informatics at under-graduate level. The hypothesis is that in developing countries, such as Iran, a web-based geo-education system can greatly improve the quantity and quality of knowledge of students in undergraduate level, which is an important step that has to be made in regard of the famous "Geo for all" motto. As a technology for conducting natural and social studies, geo-informatics offers new ways of viewing, representing and analysing information for transformative learning and teaching. Therefore, we design and present a conceptual framework of an education system and elaborate its components as well as the free and open source services and software packages that could be used in this framework for a specific case study: the Web GIS course. The goal of the proposed framework is to develop experimental GI-services in a service-oriented platform for education purposes. Finally, the paper ends with concluding remarks and some tips for future research direction.

    Incorporating research into undergraduate curricula has been linked to improved critical thinking, intellectual independence, and student retention, resulting in a graduating population more ready for the workforce or graduate school. We have designed a three-tier model of undergraduate chemistry courses that enable first-year students with no previous research experience to gain the skills needed to develop, fund and execute independent research projects by the close of their undergraduate studies. First-year students are provided with context through a broadly focused introductory class that exposes them to current faculty research activities, and also gives them direct experience with the research process through peer mentored research teams as they participate in faculty-directed projects. Mid-career undergraduate students receive exposure and support in two formats: illustrative examples from current faculty research are incorporated into lessons in core classes, and courses specially designed to foster research independence. This is done by providing content and process mentoring as students develop independent projects, write proposals, and build relationships with faculty and graduate students in research groups. Advanced undergraduates further develop their research independence performing student-designed projects with faculty collaboration that frequently result in tangible research products. Further, graduate students gain experience in mentoring though formal training, as well as through actively mentoring mid-career undergraduates. This novel, integrated approach enables faculty to directly incorporate their research into all levels of the undergraduate curriculum while fostering undergraduates in developing and executing independent projects and empowering mentoring relationships.

    The U.S. Nuclear Regulatory Commission Accident Sequence Precursor program pursues the ultimate objective of performing risk significant evaluations on operational events (precursors) occurring in commercial nuclear power plants. To achieve this objective, the Office of Nuclear Regulatory Research is supporting the development of simple probabilistic risk assessment models for all commercial nuclear power plants (NPP) in the U.S. Presently, only simple Level 1 plant models have been developed which estimate core damage frequencies. In order to provide a true risk perspective, the consequences associated with postulated core damage accidents also need to be considered. With the objective of performing risk evaluations in an integrated and consistent manner, a linked event tree approach which propagates the front end results to back end was developed. This approach utilizes simple plant models that analyze the response of the NPP containment structure in the context of a core damage accident, estimate the magnitude and timing of a radioactive release to the environment, and calculate the consequences for a given release. Detailed models and results from previous studies, such as the NUREG-1150 study, are used to quantify these simple models. These simple models are then linked to the existing Level 1 models, and are evaluated using the SAPHIRE code. To demonstrate the approach, prototypic models have been developed for a boiling water reactor, Peach Bottom, and a pressurized water reactor, Zion.

  8. BOOK REVIEW: New Understanding Physics for Advanced Level

    NASA Astrophysics Data System (ADS)

    Breithaupt, Jim

    2000-09-01

    Breithaupt's new book is big: at 727 pages, it will be a hefty addition to any student's bag. According to the preface, the book is designed to help students achieve the transition from GCSE to A-level and to succeed well at this level. It also aims to cover the requirements of the compulsory parts of all new syllabuses and to cover most of the optional material, too. The book is organized into seven themes along traditional lines: mechanics, materials, fields, waves, electricity, inside the atom, and physics in medicine. Each theme begins with a colourful title page that outlines what the theme is about, lists the applications that students will meet in their reading, identifies prior learning from GCSE and gives a checklist of what students should be able to do once they have finished their reading of the theme. This is all very useful. The text of the book is illustrated with many colourful photographs, pictures and cartoons, but despite this it looks very dense. There are a lot of words on every page in a small font that makes them seem very unfriendly, and although the book claims to be readable I rather doubt that the layout will encourage voluntary reading of the text. Each chapter ends with a useful summary and a selection of short questions that allow students to test their understanding. Each theme has a set of multiple choice and long questions. Some of the questions have an icon referring the student to the accompanying CD (more of this later). There is much up-to-date material in the book. For example, the section on cosmology gives a brief description of the inflationary scenario within the Big Bang model of the origin of the universe, although no mechanism for the inflation is given, which might prove unsatisfying to some students. I do have some reservations about the presentation of some topics within the book: the discussion of relativistic mass, for example, states that `Einstein showed that the mass ... is given by the formula ...' and quotes

    2014-02-01

    The low-level jet (LLJ) is closely related to severe rainfall events, air pollution, wind energy utilization, aviation safety, sandstorms, forest fire, and other weather and climate phenomena. Therefore, it has attracted considerable attention since its discovery. Scientists have carried out many studies on LLJs and made significant achievements during the past five or six decades. This article summarizes and assesses the current knowledge on this subject, and focuses in particular on three aspects: 1) LLJ classification, definition, distribution, and structure; 2) LLJ formation and evolutionary mechanisms; and 3) relationships between LLJ and rainfall, as well as other interdisciplinary fields. After comparing the status of LLJ research at home (China) and abroad, we then discuss the shortcomings of LLJ research in China. We suggest that this includes: coarse definitions of the LLJ, lack of observations and inadequate quality control, few thorough explorations of LLJ characteristics and formation mechanisms, and limited studies in interdisciplinary fields. The future prospects for several LLJ research avenues are also speculated.

    INEL has been involved in the development of plant-specific Accident Sequence Precursor (ASP) models for the past two years. These models were developed for use with the SAPHIRE suite of PRA computer codes. They contained event tree/linked fault tree Level 1 risk models for the following initiating events: general transient, loss-of-offsite-power, steam generator tube rupture, small loss-of-coolant-accident, and anticipated transient without scram. Early in 1995 the ASP models were revised based on review comments from the NRC and an independent peer review. These models were released as Revision 1. The Office of Nuclear Regulatory Research has sponsored several projects at the INEL this fiscal year to further enhance the capabilities of the ASP models. Revision 2 models incorporates more detailed plant information into the models concerning plant response to station blackout conditions, information on battery life, and other unique features gleaned from an Office of Nuclear Reactor Regulation quick review of the Individual Plant Examination submittals. These models are currently being delivered to the NRC as they are completed. A related project is a feasibility study and model development of low power/shutdown (LP/SD) and external event extensions to the ASP models. This project will establish criteria for selection of LP/SD and external initiator operational events for analysis within the ASP program. Prototype models for each pertinent initiating event (loss of shutdown cooling, loss of inventory control, fire, flood, seismic, etc.) will be developed. A third project concerns development of enhancements to SAPHIRE. In relation to the ASP program, a new SAPHIRE module, GEM, was developed as a specific user interface for performing ASP evaluations. This module greatly simplifies the analysis process for determining the conditional core damage probability for a given combination of initiating events and equipment failures or degradations.

    This article, which is the first of a two-part series, presents results for the first objective of The American Dietetic Association (ADA) 1991 Dietetic Practice Study: to determine the characteristics of advanced-level dietetics practice. A nationwide mail survey of ADA members was conducted on a stratified random sample of 8,012 beyond-entry-level (registered before April 1988) registered dietitians who were members of dietetic practice groups (DPGs). The sample was supplemented with two randomly selected control groups of 1,000 entry-level and 1,000 beyond-entry-level registered dietitians. The overall response rate was 63.1%. The 5,852 usable returns were representative of the dietetics population surveyed. A model of advanced-level professional practice was developed that specified minimum necessary requirements for advanced practitioners on five components: education and experience, professional achievement, approach to practice, professional role positions, and professional role contacts; measurement of a sixth component, advanced-level practice performance, was unsuccessful. A series of validation analyses found the model to be a statistically sound and reliable means of distinguishing advanced practitioners from other groups of dietitians in 8 of every 10 cases. A total of 461 (8.9%) dietitians met all requirements of the model and were classified as advanced practitioners. Projected estimations of advanced practitioners in the population of beyond-entry-level ADA members who are also members of DPGs ranged between 2,126 and 2,640 dietitians (3.5% to 4.3% of the ADA membership).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8423288

    OBJECTIVES: To establish a national profile of undergraduate training in resuscitation at Canadian medical schools, to compare the resuscitation training programs of the schools and to determine the cost of teaching seven resuscitation courses. DESIGN: Mail survey in 1989 and follow-up telephone interviews in 1991 to update and verify the information. SUBJECTS: The undergraduate deans of the 16 Canadian medical schools. INTERVENTION: The mail survey asked five questions: (a) Is completion of a standard first aid or cardiopulmonary resuscitation (CPR) course a requirement for admission to medical school? (b) Are these courses and those in basic and advanced cardiac, trauma and neurologic life support for children and adults provided to undergraduate students? (c) During which undergraduate year are these courses offered? (d) Is their successful completion required for graduation? and (e) Who funds the training courses? RESULTS: The medical schools placed emphasis on the seven courses differently. More than half the schools required the completion of courses before admission or taught some courses but did not require the completion of the courses for graduation. On average, fewer than three of the seven courses were taught, and the completion of fewer than two was required for graduation. About half of the courses were funded by the universities. The annual projected maximum cost of teaching the seven courses was $1790 per medical student. CONCLUSION: The seven resuscitation courses have not been fully implemented at the undergraduate level in Canadian medical schools. PMID:2049693

    Objectives: Leptin is a hormone-like protein produced by the adipose tissue. It plays an important role in protection of host against inflammation and infection. Some studies have reported changes in leptin levels in the gingival crevicular fluid (GCF), saliva and blood serum of patients with periodontal disease compared to healthy individuals. The aim of the present study was to compare the salivary leptin levels in patients with advanced periodontitis and healthy individuals. Materials and Methods: In this case-control study, the salivary samples of healthy individuals and patients with advanced periodontitis with clinical attachment loss >5mm were obtained using a standardized method and the leptin levels were measured in the salivary samples by means of ELISA. The effects of the periodontal status and sex on the salivary leptin levels of both groups were statistically analyzed by two-way ANOVA. Results: The means ± standard deviation (SD) of salivary leptin levels in healthy subjects and patients with advanced periodontitis were 34.27±6.88 and 17.87±5.89 pg/mL, respectively. Statistical analysis showed that the effect of sex on the salivary leptin levels was not significant (P=0.91), while the effect of advanced periodontitis on the salivary leptin levels was significant compared to healthy individuals (P<0.0001). Conclusions: In patients with advanced periodontitis, the salivary leptin levels were significantly lower compared to healthy individuals. Thus, assessment of salivary leptin can be done as a non-invasive and simple method to determine the susceptibility of patients to advanced periodontitis. PMID:27536322

    2016-01-01

    The Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalized the student experience and eliminated undergraduate specialization. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialized tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialized development in pre-university years would be accessed and reinforced predominantly through private music tuition. Drawing on this contextual literature, commencing university music undergraduates would have expectations of their prospective study founded from two historical influences. The first: How undergraduates had accessed pre-university music tuition. The second: How and in what ways undergraduates' pre-university musical activities were experienced and reinforced. Using usefulness and importance measures, the study observed the expectations of students about to commence music undergraduate studies at three representative Australian university music schools. One of these universities operated the Bologna styled model. No other known Australian study has investigated this implementation for any effects upon music undergraduate expectations. How much commencing music undergraduates would draw on their pre-university music instruction and experiences to predict their usefulness and importance expectations formed the basis for this investigation.

    2003-04-01

    For those students interested in potential clinical careers in Speech Pathology, or Audiology, a knowledge of some of the scientific bases is important, but should not create a distaste for science. The authors have addressed themselves to these goals: (1) calculation of period, Hz, summation of two sine waves, phase and dB; (2) anticipating undergraduate Speech Science; (3) simple examples of hearing pathology; and (4) basic psycho-acoustical issues. The classic material of Harry Helson was used to elucidate issues of context in experimental science, and that of S.S. Stevens was used to exemplify psycho-acoustical formulas of common use. Four texts that have been tried on approximately 200 students were evaluated. Surprisingly, the best provided the fewest formulas, short study questions with answers, good examples, and a list of common terms. The next best was aimed at slightly more advanced students, but each chapter contained introductory material, examples, and definitions suitable for naïve undergraduates. The least satisfactory text provided excerpts of technical material with abrupt transitions, no examples, and only part of the definitions needed for the naïve student. Perhaps the most difficult teaching issue is to avoid demanding graduate-level science from those undergraduates with clinical aspirations.

    Grumpy smelly, and apathy stricken middle school students often find science to be ``uncool'' and ``hands-off.'' We are changing this in our local area through an outreach program at ten participating middle schools building underwater remotely operated vehicles (ROV). Participants (300) were mentored by undergraduates (70) from BYU and instructed on various STEM topics including: electrical circuits, buoyancy, material science, design, and simple robotics. Through weekly visits these undergraduates provided teachers with immediate personal support to start their local ROV program, and enhanced their engineering curriculum at the middle school level. Each undergraduate also designed and built an instrument in an on-campus instrumentation class that were compatible with the younger student's ROVs. Designs, videos and building instructions were posted online for current and future student access. This project culminated in a timed competition where students from each school used their ROVs to collect dive rings and maneuver through an underwater obstacle course. In this talk we will discuss how to increase your own outreach efforts by connecting undergraduates with local K-12 students using inexpensive ROVs and instrumentation projects.

    Undergraduate research is one of the best ways students can experience investigative learning. Undergraduates involved in research often cite the experience as the highlight of their education. Because many geoscience departments now recognize the benefits of undergraduate research, they are creating more opportunities for students and are expecting their faculty to provide research mentoring. The Council on Undergraduate Research (CUR) is a national organization of individual and institutional members representing nearly 900 public and private colleges and universities. CUR generates awareness and support for undergraduate research and offers a variety of faculty development opportunities and services. CUR also conducts workshops where teams of faculty develop a campus plan for institutionalizing undergraduate research. A new online registry facilitates matchmaking between undergraduates with research experience and a desire to pursue an advanced degree, and graduate schools seeking high quality students who are well prepared for research. This presentation will describe the role of CUR in supporting undergraduate research, give examples of successful undergraduate research programs, and highlight some of the challenges and benefits of undergraduate research.

    Over the past 20 years health care reform has influenced the development of advanced level practitioner roles and expectations. How advanced level practitioners work to survive the highly stimulating, yet sometimes overwhelming aspects of balancing high quality provision with political reform agendas, amidst economic constraint is considered. Transformational approaches (encompassing education and practice led service development) can provide, promote and 'provoke' a harnessing of complex issues workplace environment to produce creative solutions. Transformational Practice Development provides a structured, rigorous, systematic approach that practitioners, teams and health care consumers alike can utilise to achieve skills and attributes needed for successful innovation. The authors present case study materials from action orientated locally delivered Practice Development, as a complex strategic intervention approach to influence and promote advanced level practice expertise. Initiated through facilitation of transformational leadership, and resultant team based improvements, we present how strategic collaborative processes can harness work chaos and complexity to provide sustainable and productive workplace cultures of effectiveness.

That year, the Undergraduates Teaching Undergraduates (UTU) program was begun in the chemistry department at the University of Pittsburgh. In the UTU program, undergraduates who have completed an entry-level general chemistry course are trained as peer instructors, called UTUs, for that course. Both first and second term general chemistry classes at the University of Pittsburgh employ UTUs as well as traditional graduate teaching assistants (TAs) for both recitation and laboratory sections. This study investigated the effects of the UTU program in general chemistry laboratory classes by comparing the final exams of students in traditional TA-taught sections with exams of students taught by UTUs. The project was divided into two phases; the preparative measurement development phase in which the coding scheme and rubrics for analyzing the questions were developed and the evaluative learning outcome phase which assessed the students' achievement by examining their responses to three assessment questions. These questions dealt with student awareness of the structure of an experiment in terms of goals, procedures, conclusions and chemical concepts, logical thinking and verbal and written communication skills. The results of the analysis show that students in the UTU sections performed consistently better than students in TA sections, especially in areas that require critical thinking and understanding skills. In no cases examined were the learning outcomes negatively affected by UTU instruction.

    The dietetics profession lacks a comprehensive definition of advanced-level practice. Using a three-round Delphi study with mailed surveys, expert consensus on four dimensions of advanced-level practice that define advanced practice registered dietitians (RDs) in clinical nutrition was explored. Purposive sampling identified 117 RDs who met advanced-level practice criteria. In round 1, experts rated the essentiality of statements on a 7-point ordinal scale and generated open-ended practice activity statements regarding the following four dimensions of advanced-level practice: professional knowledge, abilities and skills, approaches to practice, roles and relationships, and practice behaviors. Median ratings of 1.0 to 3.0 were defined as essential, 4.0 was neutral, and 5.0 to 7.0 were nonessential. In rounds 2 and 3, experts re-rated statements not reaching consensus by evaluating their previous responses, group median rating, and comments. Consensus was reached when the interquartile range of responses to a statement was ≤2.0. Eighty-five experts enrolled (72.6%); 76 (89.4%) completed all rounds. In total, 233 statements were rated, with 100% achieving consensus; 211 (90.6%) were essential to advanced practice RD clinical practice. Having a master's degree; completing an advanced practice residency; research coursework; and advanced continuing education were essential, as were having 8 years of experience; clinical nutrition knowledge/expertise; specialization; participation in research activities; and skills in technology and communication. Highly essential approaches to practice were systematic yet adaptable and used critical thinking and intuition and highly essential values encompassed professional growth and service to patients. Roles emphasized patient care and leadership. Essential practice activities within the nutrition care process included provision of complex patient-centered nutrition care using application of advanced knowledge/expertise and

    We present status and plans for our ongoing efforts to develop data analysis and problem-solving skills through Undergraduate Astronomy instruction. While our initiatives were developed with UM-Dearborn’s student body primarily in mind, they should be applicable for a wide range of institution and of student demographics. We focus here on two strands of our effort.Firstly, students in our Introductory Astronomy (ASTR 130) general-education course now perform several “Data Investigations”, in which they interrogate the Hubble Legacy Archive to illustrate important course concepts. This was motivated in part by the realization that typical public data archives now include tools to interrogate the observations that are sufficiently accessible that introductory astronomy students can use them to perform real science, albeit mostly at a descriptive level. We are continuing to refine these investigations, and, most importantly, to critically assess their effectiveness in terms of the student learning outcomes we wish to achieve. This work is supported by grant HST-EO-13758, provided by NASA through a grant from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.Secondly, at the advanced-undergraduate level, students taking courses in our Astronomy minor are encouraged to gain early experience in techniques of astronomical observation and analysis that are used by professionals. We present two example projects from the Fall 2015 iteration of our upper-division course ASTR330 (The Cosmic Distance Ladder), one involving Solar System measurements, the second producing calibrated aperture photometry. For both projects students conducted, analysed, and interpreted observations using our 0.4m campus telescope, and used many of the same analysis tools as professional astronomers. This work is supported partly from a Research Initiation and Seed grant from the

    Xue, Feng; Zhu, Lin; Wang, Liyan; Wang, Quan

    2015-01-01

    To analyze the clinical and prognostic value of neuron specific enolase (NSE) levels in serum of advanced lung cancer patients, we analyzed serum NSE level of 110 advanced lung cancer patients (case group), 100 benign lung disease patients (benign disease group), and 100 healthy persons (control group). Case group patients were divided by NSE level into ≥25 ng/mL (52 cases) and <25 ng/mL (58 cases) groups to analyze overall survival (OS) and progression-free survival (PFS). The results showed the serum NSE levels of case group patients were significantly higher than those of control or benign disease group patients (P<0.05). Serum NSE levels of small cell lung cancer patients were significantly higher than those of patients with other tumor pathologies (all P<0.05). Median OS significantly differed between patients with NSE levels ≥25 ng/mL (23.7 months) and <25 ng/mL (31.4 months) (P<0.05). Median PFS also significantly differed between patients with NSE levels ≥25 ng/mL (13.5 months) and <25 ng/mL (17.6 months) (χ 2=9.992; P<0.05). Tumor pathology (RR=4.136), patient performance status score (RR=2.903), and serum NSE level (RR=2.338) were factors influencing OS (P<0.05). Patient performance status score (RR=2.903), number of chemotherapy lines (RR=1.776), and serum NSE level (RR=2.075) were influencing factors in patients’ PFS (P<0.05). In brief, serum NSE level significantly correlates with advanced lung cancer patient prognosis and may be useful as an auxiliary index to predict prognosis. PMID:26309614

  15. Five levels of PACS modularity: integrating 3D and other advanced visualization tools.

    PubMed

    Wang, Kenneth C; Filice, Ross W; Philbin, James F; Siegel, Eliot L; Nagy, Paul G

    2011-12-01

    The current array of PACS products and 3D visualization tools presents a wide range of options for applying advanced visualization methods in clinical radiology. The emergence of server-based rendering techniques creates new opportunities for raising the level of clinical image review. However, best-of-breed implementations of core PACS technology, volumetric image navigation, and application-specific 3D packages will, in general, be supplied by different vendors. Integration issues should be carefully considered before deploying such systems. This work presents a classification scheme describing five tiers of PACS modularity and integration with advanced visualization tools, with the goals of characterizing current options for such integration, providing an approach for evaluating such systems, and discussing possible future architectures. These five levels of increasing PACS modularity begin with what was until recently the dominant model for integrating advanced visualization into the clinical radiologist's workflow, consisting of a dedicated stand-alone post-processing workstation in the reading room. Introduction of context-sharing, thin clients using server-based rendering, archive integration, and user-level application hosting at successive levels of the hierarchy lead to a modularized imaging architecture, which promotes user interface integration, resource efficiency, system performance, supportability, and flexibility. These technical factors and system metrics are discussed in the context of the proposed five-level classification scheme. PMID:21301923

    Imamura, G.; Mika, K.; Lin, T.; Lee, C.; Lin, C.; Jay, J.

    2007-12-01

    Service-learning is a pedagogy that combines academic rigor with activities that address human and community needs. Over the past three years, we have developed a service-learning course that involves UCLA students working with 6th graders in an economically disadvantaged neighborhood to address issues of environmental science and health. This past year UCLA students conducted a research project in collaboration with a middle school class to investigate levels of pathogen-indicating organisms in beach sand near the Santa Monica pier. All students were taught necessary methods in class by the UCLA professor, and then met at the field site. Fieldwork involved collection of water and sand samples from various locations, extraction of bacteria from sand by shaking with buffer and decanting, and addition of sample to growth media that allow quantification of two organisms, Escherichia coli and enterococci. These organisms are typically used to indicate fecal contamination of water. Methods were straightforward and were accomplished by the 6th graders with only modest supervision by the UCLA students. Results showed extremely high levels of pathogen indicating organisms in the vicinity of a diverted stormdrain, indicating a continuing problem with the diversion. Levels decreased with distance away from the stormdrain, indicating migration of the organisms from the site of the diversion. UCLA students then visited the sixth grade classroom to help the sixth graders create Powerpoint posters including statement of hypotheses, graphs of the results, pictures of the entire process, and conclusions. Middle school students then visited UCLA to tour the campus and present their posters at a poster session hosted by the Center for Embedded Networked Sensing at UCLA. Desired outcomes at the 6th grade level included: 1) increased interest in science; 2) greater knowledge of and interest in attending college; and 3) enhanced knowledge of and feeling of political empowerment

  17. Assessing Undergraduate University Students' Level of Knowledge, Attitudes and Behaviour Towards Biodiversity: A case study in Cyprus

    NASA Astrophysics Data System (ADS)

    Nisiforou, Olympia; Charalambides, Alexandros George

    2012-05-01

    Biodiversity is a key resource as it provides both goods and services to society. However, humans value these resources differently, especially when biodiversity is exploited for its economic potential; a destruction on a scale rarely seen before. In order to decrease the threats that biodiversity is facing due to human activity, globally (climate change) and locally (economic development), individuals must have fundamental knowledge and exhibit appropriate behaviour towards biodiversity and its values. Nevertheless, the effect of human's knowledge, policies and attitudes towards biodiversity's protection are often limited by insufficient education and public support. A balance between the use of resources and technology, reconciling economic development and the need to maintain biodiversity is a challenge. The current paper looks into the knowledge level, attitudes and behaviour of university students of the Department of Environmental Science and Technology at the Cyprus University of Technology towards biodiversity. The investigation was carried out using a closed format questionnaire on a sample of first- and second-year university students (n = 44), in order to access their perceptions and attitudes towards environmental issues regarding biodiversity. The questionnaire was derived from relevant literature. The test results showed that there are significant differences with regard to the level of knowledge about biodiversity between the two groups. However, no significant differences were found on attitudes and behaviour towards biodiversity. The results have also shown that all students have a positive attitude towards biodiversity, while on the other hand, they find themselves, most of the time, unwilling to engage in environmental behaviour.

  18. The relationship of certified flight instructors' emotional intelligence levels on flight student advancement

    NASA Astrophysics Data System (ADS)

    Hokeness, Mark Merrill

    Aviation researchers estimate airline companies will require nearly 500,000 pilots in the next 20 years. The role of a Certified Flight Instructor (CFI) is to move student pilots to professional pilots with training typically conducted in one-on-one student and instructor sessions. The knowledge of aviation, professionalism as a teacher, and the CFI’s interpersonal skills can directly affect the successes and advancement of a student pilot. A new and emerging assessment of people skills is known as emotional intelligence (EI). The EI of the CFI can and will affect a flight students’ learning experiences. With knowledge of emotional intelligence and its effect on flight training, student pilot dropouts from aviation may be reduced, thus helping to ensure an adequate supply of pilots. Without pilots, the growth of the commercial aviation industry will be restricted. This mixed method research study established the correlation between a CFI’s measured EI levels and the advancement of flight students. The elements contributing to a CFI’s EI level were not found to be teaching or flight-related experiences, suggesting other life factors are drawn upon by the CFI and are reflected in their emotional intelligence levels presented to flight students. Students respond positively to CFIs with higher levels of emotional intelligence. Awareness of EI skills by both the CFI and flight student contribute to flight student successes and advancement.

  19. Decreased melatonin levels and increased levels of advanced oxidation protein products in the seminal plasma are related to male infertility.

    2016-03-01

    Melatonin, an indolamine secreted by the pineal gland, is known as a powerful free-radical scavenger and wide-spectrum antioxidant. Therefore, the aim of this study was to correlate markers of oxidative protein damage (advanced oxidation protein products, AOPPs) and the total antioxidant capacity (TAC) with melatonin levels in the seminal plasma of men with azoospermia (n=37), theratozoospermia (n=29) and fertile controls (normozoospermia, n=37). Melatonin concentration was measured by radioimmunoassay. The levels of AOPP as well as TAC efficiency (determined by the ferric reducing antioxidant power, FRAP) were estimated by spectrophotometric methods. The concentration of melatonin and AOPP significantly differed in azoospermic (P<0.0001) and theratozoospermic (P<0.0001) patients versus fertile men, and correlated negatively (r=-0.33, P=0.0016). The TAC levels were significantly higher in azoospermia than in theratozoospermia (P=0.0022) and the control group (P=0.00016). In azoospermia, the AOPP concentration was also significantly higher than that observed in theratozoospermia (P=0.00029). Decreased levels of melatonin together with elevated AOPP altered the oxidative-antioxidative balance in the ejaculate, thereby reducing fertility. Therefore, melatonin and AOPP levels may serve as additional diagnostic markers of semen quality and male reproductive potential. PMID:25218686

    NASA Astrophysics Data System (ADS)

    Reinen, L. A.

    2011-12-01

    The Mw 9.0 Tohoku-Oki earthquake of March 11, 2011 - with its combination of a very large earthquake, subsequent tsunami and damage to nuclear power plants - was a disaster of historically unprecedented proportions that dominated news reports and captured the attention of the world. It also provided an opportunity to engage students in the classroom via active research into an on-going major seismic event. As part of an intermediate-level undergraduate course in Neotectonics, six students participated in a 4-week research project to assess the Tohoku-Oki earthquake and its aftereffects, and make general predictions for similar events on the active margin of the western United States. In a series of guided inquiries, student teams addressed questions of: [1] Regional setting (e.g., tectonic plates, convergence velocities and directions, and distribution of population, nuclear plants and topography); [2] Historic and present-day seismicity (e.g., earthquake recurrence, and aftershock adherence to predicted Bath, Omori, and Gutenberg-Richter relationships); and [3] Application to the western United States (Cascadia or Southern California). With each subsequent question set student independence increased, moving from initial steps of the tectonic setting and historical seismicity of Japan, to the important components on which teams could focus their efforts for the Cascadia or Southern California regions. I will present results from this teaching experiment and examples of the student projects, including the students' preparation for this assignment. Discussion and suggestions (particularly about effective means of conducting rigorous long-term assessment of student learning) are strongly encouraged.

  8. A new hydrostatic leveling system developed for the Advanced Photon Source.

    SciTech Connect

    Kivioja, L. A.

    1998-09-18

    As a result of the calibration tests performed with the first prototype units using the new measurement principle, we believe that the described leveling method is stable and accurate to the micron level with a sufficiently large range for the expected elevation changes of the support girders used in the Advanced Photon Source (APS) storage ring. Although long-term studies with this system have not been conducted, we believe that after installation this system requires little or no servicing for long periods of time. The methods described in this paper cover only the elevation changes of individual vessels. However, changes in the tilt of a girder must also be known. Therefore, a combination of tiltmeters in conjunction with this hydrostatic level system (HLS) would be most suitable for measuring the tilt and elevation changes of the APS girders.

    BACKGROUND We previously cloned prosaposin (PSAP) from metastatic castrate-resistant prostate cancer (mCRPCa) cells and demonstrated its genomic amplification and/or overexpression in metastatic PCa cell lines, xenografts, and lymph node metastases. The clinicohistopathological significance of serum-PSAP levels and its tissue expression and association with predictive or prognostic variable in primary or advanced PCa are not known. METHODS We examined PSAP expression by immunohistochemical staining during early embryogenic development of the prostate and within a large tissue microarray which included 266 benign and malignant prostate tissues. In addition, serum PSAP levels in the age-adjusted normal male population and in 154 normal individuals and patients with primary or mCRPCa were measured by an ELISA assay. RESULTS Univariate and multivariate analyses revealed a significant and inverse association between PSAP expression and clinical stage II and III tumors, dominant Gleason patterns 3 and 4, and seminal vesicle invasion. In the normal male population, the lowest serum-PSAP level was detected before puberty, peaked at the most reproductive age group (20–39 years old), and then, decreased to a range between the two groups for men above 40 years old. Regardless of age and when compared with normal individuals, serum-PSAP levels significantly decreased in primary organ-confined PCa, but increased in those with mCRPCa. CONCLUSION Our results show that PSAP has the potential to differentiate between primary and advanced PCa. Additional large-scale studies are needed to define the usefulness of tissue expression or serum-PSAP levels as a diagnostic or prognostic marker or as a therapeutic target in PCa. PMID:21630292

    The growing neuroscientific understanding of the biological basis of behaviors has profound social and ethical implications. To address the need for public awareness of the consequences of these advances, we developed an undergraduate neuroethics course, Neuroscience and Society, at the University of Minnesota. Course evolution, objectives, content, and impact are described here. To engage all students and facilitate undergraduate ethics education, this course employed daily reading, writing, and student discussion, case analysis, and team presentations with goals of fostering development of moral reasoning and judgment and introducing application of bioethical frameworks to topics raised by neuroscience. Pre- and post-course Defining Issues Test (DIT) scores and student end-of-course reflections demonstrated that course objectives for student application of bioethical frameworks to neuroethical issues were met. The active-learning, student-centered pedagogical approaches used to achieve these goals serve as a model for how to effectively teach neuroethics at the undergraduate level. PMID:25838802

    We have previously shown that the tumor necrosis factor family member a proliferation-inducing ligand (APRIL) enhances intestinal tumor growth in various preclinical tumor models. Here, we have investigated whether APRIL serum levels at time of surgery predict survival in a large cohort of colorectal cancer (CRC) patients. We measured circulating APRIL levels in a cohort of CRC patients (n=432) using a novel validated monoclonal APRIL antibody (hAPRIL.133) in an enzyme-linked immunosorbent assay (ELISA) setup. APRIL levels were correlated with clinicopathological features and outcome. Overall survival was examined with Kaplan-Meier survival analysis, and Cox proportional hazards ratios were calculated. We observed that circulating APRIL levels were normally distributed among CRC patients. High APRIL expression correlated significantly with poor outcome measures, such as higher stage at presentation and development of lymphatic and distant metastases. Within the group of rectal cancer patients, higher circulating APRIL levels at time of surgery were correlated with poor survival (log-rank analysis P-value 0.008). Univariate Cox regression analysis for overall survival in rectal cancer patients showed that patients with elevated circulating APRIL levels had an increased risk of poor outcome (hazard ratio (HR) 1.79; 95% confidence interval (CI) 1.16-2.76; P-value 0.009). Multivariate analysis in rectal cancer patients showed that APRIL as a prognostic factor was dependent on stage of disease (HR 1.25; 95% CI 0.79-1.99; P-value 0.340), which was related to the fact that stage IV rectal cancer patients had significantly higher levels of APRIL. Our results revealed that APRIL serum levels at time of surgery were associated with features of advanced disease and prognosis in rectal cancer patients, which strengthens the previously reported preclinical observation of increased APRIL levels correlating with disease progression.

    A number of waste components in US defense high level radioactive wastes (HLW) have proven challenging for current Joule heated ceramic melter (JHCM) operations and have limited the ability to increase waste loadings beyond already realized levels. Many of these "troublesome" waste species cause crystallization in the glass melt that can negatively impact product quality or have a deleterious effect on melter processing. Recent efforts at US Department of Energy laboratories have focused on understanding crystallization behavior within HLW glass melts and investigating approached to mitigate the impacts of crystallization so that increases in waste loading can be realized. Advanced glass formulations have been developed to highlight the unique benefits of next-generation melter technologies such as the Cold Crucible Induction Melter (CCIM). Crystal-tolerant HLW glasses have been investigated to allow sparingly soluble components such as chromium to crystallize in the melter but pass out of the melter before accumulating.

    In this article, we present a practical coordinated multipoint (CoMP) system for LTE-Advanced. In this CoMP system, cooperation is enabled for cell-edge users via dynamic switching between the normal single-cell operation and CoMP. We first formulate a general CoMP system model of several CoMP schemes. We then investigate a practical finite-rate feedback design that simultaneously supports interference coordination, joint transmission (JT), and dynamic point selection (DPS) with a varying number of cooperating transmission points while operating a single-cell transmission as a fallback mode. We provide both link-level and system-level results for the evaluation of different feedback options for general CoMP operation. The results show that there are substantial performance gains in cell-edge throughputs for both JT and DPS CoMP over the baseline Release 10 LTE-Advanced with practical feedback options. We also show that CoMP can enable improved mobility management in real networks.

    Background: Advanced glycation end-products (AGEs) can accumulate in organs and tissues during ageing and diabetes. Increased levels of AGEs are found in the bone tissue of patients with osteoporosis. The purpose of this study was to evaluate circulating AGEs in patients with osteoporosis. Methods: We evaluated plasma AGEs, osteoporosis-related biomarkers, and bone mass in 82 menopausal women with osteoporosis or osteopenia, 16 young women with osteopenia, and 43 healthy women without osteoporosis or osteopenia. Results: Higher levels of serum AGEs were found in the osteoporosis or osteopenia group compared to healthy women (P < 0.0001). A negative correlation was observed between serum AGEs and lumbar spine bone density (BMD of lumbar spine, r = -0.249, P = 0.028; T-score of lumbar spine, r = -0.261, P = 0.021). Women with a increased level of serum AGEs (> 8.12 U/mL) had a 5.34-fold risk of osteopenia regarding lumbar spine T-score and a 3.31-fold risk of osteopenia regarding the hip T-score. Conclusion: Serum AGEs could be used to monitor the severity and progression of osteoporosis. An increased serum level of AGEs was associated with impaired bone formation and was a risk factor for the development of osteoporosis. Targeting AGEs may represent a novel therapeutic approach for primary or secondary osteoporosis. PMID:24688308

    Maintaining a productive research lab at the undergraduate level requires a savvy combination of internal organization, high (but realistic) expectations, and adaptation of one's research interests into semester- and summer-length projects. Several key strategies can help achieve the goal of building a lab culture that both enriches students' academic experiences and advances one's own scholarly research and visibility. Foremost among these is the need to maintain momentum and preserve institutional knowledge in an environment where undergraduate students' lifetime in an individual lab may only last a year or two. Examples from the Environmental Geochemistry Lab at Chapman University (www.chapman.edu/envgeo) developed over several years and with 40+ undergraduate students will be presented which can be transferable to other faculty research labs in the earth sciences. Approaches to writing successful external research grant proposals at a primarily undergraduate institution (PUI) and strategies for both personal and institutional time management/savings will also be discussed, with a focus on new models at Chapman offered to further incentivize faculty involvement in undergraduate research.

    In this study we investigated the association between plasma levels of eight forms of vitamin E and incidence of Alzheimer's disease (AD) among oldest-old individuals in a population-based setting. A dementia-free sample of 232 subjects aged 80+ years, derived from the Kungsholmen Project, was followed-up to 6 years to detect incident AD. Plasma levels of vitamin E (alpha-, beta-, gamma, and delta-tocopherol; alpha-, beta-, gamma-, and delta-tocotrienol) were measured at baseline. Vitamin E forms-AD association was analyzed with Cox proportional hazard model after adjustment for several potential confounders. Subjects with plasma levels of total tocopherols, total tocotrienols, or total vitamin E in the highest tertile had a reduced risk of developing AD in comparison to persons in the lowest tertile. Multi-adjusted hazard ratios (HRs) and 95% confidence interval (CI) were 0.55 (0.32-0.94) for total tocopherols, 0.46 (0.23-0.92) for total tocotrienols, and 0.55 (0.32-0.94) for total vitamin E. When considering each vitamin E form, the risk of developing AD was reduced only in association with high plasma levels of beta-tocopherol (HR: 0.62, 95% CI 0.39-0.99), whereas alpha-tocopherol, alpha- tocotrienol, and beta-tocotrienol showed only a marginally significant effect in the multiadjusted model [HR (95% CI): alpha-tocopherol: 0.72 (0.48-1.09); alpha-tocotrienol: 0.70 (0.44-1.11); beta-tocotrienol: 0.69 (0.45-1.06)]. In conclusion, high plasma levels of vitamin E are associated with a reduced risk of AD in advanced age. The neuroprotective effect of vitamin E seems to be related to the combination of different forms, rather than to alpha-tocopherol alone, whose efficacy in interventions against AD is currently debated.

    Context Serum creatinine has been reported to increase in patients receiving Vemurafenib, yet neither the prevalence nor the mechanism of this adverse event are known. Objective We aimed to evaluate the frequency and the mechanisms of increases in plasma creatinine level in patients receiving Vemurafenib for advanced melanoma. Methods We performed a retrospective monocentric study including consecutive patients treated with Vemurafenib for an advanced melanoma. We collected clinical and biological data concerning renal function before introduction of Vemurafenib and in the course of monthly follow-up visits from March 2013 to December 2014. Cystatin C-derived glomerular filtration rate was evaluated before and after Vemurafenib initiation, as increase in serum cystatin C is specific to a decrease in the glomerular filtration rate. We also performed thorough renal explorations in 3 patients, with measurement of tubular secretion of creatinine before and after Vemurafenib initiation and a renal biopsy in 2 patients. Results 70 patients were included: 97% of them displayed an immediate, and thereafter stable, increase in creatinine (+22.8%) after Vemurafenib initiation. In 44/52 patients in whom Vemurafenib was discontinued, creatinine levels returned to baseline. Serum cystatin C increased, although proportionally less than serum creatinine, showing that creatinine increase under vemurafenib was indeed partly due to a renal function impairment. In addition, renal explorations demonstrated that Vemurafenib induced an inhibition of creatinine tubular secretion. Conclusion Thus, Vemurafenib induces a dual mechanism of increase in plasma creatinine with both an inhibition of creatinine tubular secretion and slight renal function impairment. However, this side effect is mostly reversible when Vemurafenib is discontinued, and should not lead physicians to discontinue the treatment if it is effective. PMID:26930506

  6. Levels of acute inflammatory biomarkers in advanced prostate cancer patients with α2-macroglobulin deficiency.

    2011-12-01

    C-reactive protein (CRP), serum amyloid A (SAA), interleukin-6 (IL-6), α1-antitrypsin (α1AT), α1-acid glycoprotein (α1AG) and ceruloplasmin (CP) are acute inflammatory biomarkers that increase in various conditions including infection, inflammation, malignancy and tissue disturbance. In contrast, α2-macroglobulin (α2M) is involved in inflammation through its function as a carrier protein of IL-6. We had previously reported on advanced prostate cancer (PCa) patients with multiple distant bone metastases in whom serum α2M levels were markedly decreased (α2M deficiency). However, the relationship between serum levels of α2M and acute inflammatory biomarkers in PCa patients with or without α2M deficiency has not been demonstrated. In the present study, we examined serum levels of CRP, SAA, IL-6, α1AT, α1AG and CP in PCa patients with or without α2M deficiency to establish clinical significance and changes in these biomarkers during PCa disease progression. We found that upon addition of recombinant IL-6 (rIL-6) to serum from PCa patients with α2M deficiency, since a function of α2M is to bind and stabilize IL-6, the α2M-IL-6 complex and free endogenous IL-6 were not detectable. Serum levels of the α2M-independent markers, α1AT, α1AG and CP, in all PCa patients regardless of α2M deficiency were significantly higher than in healthy controls, but those of the α2M-dependent molecules, CRP, SAA and IL-6, were not increased in PCa patients with α2M deficiency. Therefore, quantitation of both α2M-dependent (CRP, SAA and IL-6) and α2M-independent (α1AT, α1AG and CP) acute inflammatory biomarkers in advanced PCa patients may be an auxiliary indicator, together with prostate-specific antigen (PSA), to monitor PCa disease progression.

    Undergraduate research is a proven effective pedagogy that has a number of benefits including: enhancing student learning through mentoring relationships with faculty; increasing retention; increasing enrollment in graduate programs; developing critical thinking, creativity, problem solving and intellectual independence; and, developing an understanding of research methodology. Undergraduate research also has been demonstrated in preparing students for careers. In addition to developing disciplinary and technical expertise, participation in undergraduate research helps students improve communication skills (written, oral, and graphical) and time management. Early involvement in undergraduate research improves retention and, for those engaged at the 2YC level, helps students successfully transfers to 4YC. The Geosciences Division of the Council on Undergraduate Research (GeoCUR) supports faculty in their development of undergraduate research programs at all levels. GeoCUR leads workshops for new and future faculty covering all aspects of undergraduate research including incorporating research into coursework, project design, mentoring students, sustaining programs, and funding sources. GeoCUR members support new faculty by providing a range of services including: peer-review of grant proposals; advice on establishing an undergraduate research program; balancing teaching and research demands; and networking with other geoscientist. GeoCUR has also developed web resources that support faculty and departments in development of undergraduate research programs (http://serc.carleton.edu/NAGTWorkshops/undergraduate_research/index.html). This presentation will describe the services provided by GeoCUR and highlight examples of programs and resources available to geoscientists in all career stages for effective undergraduate research mentoring and development.

    To support future NASA deep space missions, a radioisotope power system utilizing Stirling power conversion technology was under development. This development effort was performed under the joint sponsorship of the Department of Energy and NASA, until its termination at the end of 2013 due to budget constraints. The higher conversion efficiency of the Stirling cycle compared with that of the Radioisotope Thermoelectric Generators (RTGs) used in previous missions (Viking, Pioneer, Voyager, Galileo, Ulysses, Cassini, Pluto New Horizons and Mars Science Laboratory) offers the advantage of a four-fold reduction in Pu-238 fuel, thereby extending its limited domestic supply. As part of closeout activities, system-level testing of flight-like Advanced Stirling Convertors (ASCs) with a flight-like ASC Controller Unit (ACU) was performed in February 2014. This hardware is the most representative of the flight design tested to date. The test fully demonstrates the following ACU and system functionality: system startup; ASC control and operation at nominal and worst-case operating conditions; power rectification; DC output power management throughout nominal and out-of-range host voltage levels; ACU fault management, and system command / telemetry via MIL-STD 1553 bus. This testing shows the viability of such a system for future deep space missions and bolsters confidence in the maturity of the flight design.

    Lees-Deutsch, Liz; Christian, Jan; Setchfield, Ian

    2016-01-01

    This article conveys concerns raised by delegates at the International SAM Conference (Manchester, 2015) regarding how to advance nursing practice in acute medicine. It endeavors to capture the essence of 'how to advance practice' and 'how to integrate advanced practice' within the workforce structures of an acute medicine unit (AMU). It addresses the production of tacit knowledge and the recognition and integration of this to developing the nursing workforce. The current context of NHS efficiencies and recruitment issues emphasize the value of retaining tacit knowledge. Uniquely, this article offers an early conceptual framework through which levels of advancement and potential transition points to advance nursing practice in acute medicine are articulated. Determining how to advance requires identification of prior accomplishments such as, tacit knowledge, experiential learning, CPD, specialist courses and management experience. This requires nurses to make judicious decisions to advance their practice and the distinction between 'amassing experience' and 'career progression'. It aims to stimulate thinking around the practicalities of advancement, the value of tacit knowledge and potential realization through the framework trajectory. PMID:27441313

    2012-04-01

    This empirical study explores factors influencing undergraduates' self-evaluation of their numerical competence, using data from an online survey completed by 566 undergraduates from a diversity of academic disciplines, across all four faculties at a post-1992 UK university. Analysis of the data, which included correlation and multiple regression analyses, revealed that undergraduates exhibiting greater confidence in their mathematical and numeracy skills, as evidenced by their higher self-evaluation scores and their higher scores on the confidence sub-scale contributing to the measurement of attitude, possess more cohesive, rather than fragmented, conceptions of mathematics, and display more positive attitudes towards mathematics/numeracy. They also exhibit lower levels of mathematics anxiety. Students exhibiting greater confidence also tended to be those who were relatively young (i.e. 18-29 years), whose degree programmes provided them with opportunities to practise and further develop their numeracy skills, and who possessed higher pre-university mathematics qualifications. The multiple regression analysis revealed two positive predictors (overall attitude towards mathematics/numeracy and possession of a higher pre-university mathematics qualification) and five negative predictors (mathematics anxiety, lack of opportunity to practise/develop numeracy skills, being a more mature student, being enrolled in Health and Social Care compared with Science and Technology, and possessing no formal mathematics/numeracy qualification compared with a General Certificate of Secondary Education or equivalent qualification) accounted for approximately 64% of the variation in students' perceptions of their numerical competence. Although the results initially suggested that male students were significantly more confident than females, one compounding variable was almost certainly the students' highest pre-university mathematics or numeracy qualification, since a higher

    2014-01-01

    Functionalized nanoporous materials have been developed recently as bio/chemical sensing materials. Due to the huge specific surface of the nano-materials for molecular adsorption, high hopes have been placed on gravimetric detection with micro/nano resonant cantilevers for ultra-sensitive sensing of low-concentration bio/chemical substances. In order to enhance selectivity of the gravimetric resonant sensors to the target molecules, it is crucial to modify specific groups onto the pore-surface of the nano-materials. By loading the nanoporous sensing material onto the desired region of the mass-type transducers like resonant cantilevers, the micro-gravimetric bio/chemical sensors can be formed. Recently, such micro-gravimetric bio/chemical sensors have been successfully applied for rapid or on-the-spot detection of various bio/chemical molecules at the trace-concentration level. The applicable nanoporous sensing materials include mesoporous silica, zeolite, nanoporous graphene oxide (GO) and so on. This review article focuses on the recent achievements in design, preparation, functionalization and characterization of advanced nanoporous sensing materials for micro-gravimetric bio/chemical sensing.

    The feedwater control system in the Advanced Boiling Water Reactor (ABWR) is more challenging to design compared to other control systems in the plant, due to the possible change in level from void collapses and swells during transient events. A basic fuzzy logic controller is developed using a simplified ABWR mathematical model to demonstrate and compare the performance of this controller with a simplified conventional controller. To reduce the design effort, methods are developed to automatically tune the scaling factors and control rules. As a first step in developing the fuzzy controller, a fuzzy controller with a limited number of rules is developed to respond to normal plant transients such as setpoint changes of plant parameters and load demand changes. Various simulations for setpoint and load demand changes of plant performances were conducted to evaluate the modeled fuzzy logic design against the simplified ABWR model control system. The simulation results show that the performance of the fuzzy logic controller is comparable to that of the Proportional-Integral (PI) controller, However, the fuzzy logic controller produced shorter settling time for step setpoint changes compared to the simplified conventional controller.

    /NETL managed National Mineral Sequestration Working Group we have already significantly improved our understanding of mineral carbonation. Group members at the Albany Research Center have recently shown that carbonation of olivine and serpentine, which naturally occurs over geological time (i.e., 100,000s of years), can be accelerated to near completion in hours. Further process refinement will require a synergetic science/engineering approach that emphasizes simultaneous investigation of both thermodynamic processes and the detailed microscopic, atomic-level mechanisms that govern carbonation kinetics. Our previously funded Phase I Innovative Concepts project demonstrated the value of advanced quantum-mechanical modeling as a complementary tool in bridging important gaps in our understanding of the atomic/molecular structure and reaction mechanisms that govern CO{sub 2} mineral sequestration reaction processes for the model Mg-rich lamellar hydroxide feedstock material Mg(OH){sub 2}. In the present simulation project, improved techniques and more efficient computational schemes have allowed us to expand and augment these capabilities and explore more complex Mg-rich, lamellar hydroxide-based feedstock materials, including the serpentine-based minerals. These feedstock materials are being actively investigated due to their wide availability, and low-cost CO{sub 2} mineral sequestration potential.

  1. Ecological Effects of Sea Level Rise: Advancing coastal management through integrated research and engagement

    Kidwell, D. M.

    2012-12-01

    Rising sea level represents a significant threat to coastal communities and ecosystems through land loss, altered habitats, and increased vulnerability to coastal storms and inundation. This threat is exemplified in the northern Gulf of Mexico where low topography, expansive marshes, and a prevalence of tropical storms have already resulted in extensive coastal impacts. The development of robust predictive capabilities that incorporate complex biological processes with physical dynamics are critical for informed planning and restoration efforts for coastal ecosystems. Looking to build upon existing predictive modeling capabilities and allow for use of multiple model (i.e., ensemble) approaches, NOAA initiated the Ecological Effects of Sea Level Rise program in 2010 to advance physical/biological integrative modeling capabilities in the region with a goal to provide user friendly predictive tools for coastal ecosystem management. Focused on the northern Gulf of Mexico, this multi-disciplinary project led by the University of Central Florida will use in situ field studies to parameterize physical and biological models. These field studies will also result in a predictive capability for overland sediment delivery and transport that will further enhance marsh, oyster, and submerged aquatic vegetation models. Results from this integrated modeling effort are envisioned to inform management strategies for reducing risk, restoration and breakwater guidelines, and resource sustainability for project planning, among other uses. In addition to the science components, this project incorporates significant engagement of the management community through a management applications principle investigator and an advisory management committee. Routine engagement between the science team and the management committee, including annual workshops, are focused on ensuring the development of applicable, relevant, and useable products and tools at the conclusion of this project.

  3. Advances in Instrumentation for Quantification of Isotopic Nitrous Oxide from ppb levels to 100%

    The isotopic composition of trace gases provides information of their origin and fate that cannot be determined from their concentration measurements alone. Biological source and loss processes, like bacterial production of nitrous oxide, are typically accompanied by isotopic selectivity associated with the kinetics of bond formation and destruction. Of the three important biologically mediated greenhouse gases (CO2, CH4 and N2O), the understanding of nitrous oxide isotopic budget in air lags behind the other two gases primarily due to the relatively low concentration of N2O in ambient air (~320 ppb). Furthermore, the origin of nitrates in rivers, lakes, ocean and other water supplies may be determined from analyses of isotopic nitrous oxide produced via chemical reduction or biological conversion. These processes can produce nitrous oxide at levels considerably greater than those present in ambient air. To date, analyses of isotopic nitrous oxide requires either pre-concentration of samples containing low concentrations or dilution of samples with high concentrations. We report significant advances of instrumentation for real-time measurements of site-specific isotopic nitrogen (δ15Nα, δ15Nβ, δ15N, δ18O) and mixing ratio [N2O] of nitrous oxide over a very wide range of mole fractions in air. Specifically, LGR's Isotopic N2O Analyzer can report site-specific isotopic nitrogen and isotopic oxygen continuously in flows ranging from 0.2 to over 20 ppm (parts per million) nitrous oxide in air (with preconcentration or dilution). Furthermore, for samples of limited volume, a batch technique may be used for similar isotopic measurements in discrete samples containing 0.2 ppm to 100% nitrous oxide (e.g., sample volumes from bacterial digestion can be as little as 1-10 mL). This novel technology, which employs cavity enhanced absorption spectroscopy (Off-Axis ICOS) and a mid-infrared laser (4.56 microns) and does not require any cryogenic components, has been

  4. Advanced waste form and Melter development for treatment of troublesome high-level wastes

    Marra, James; Kim, Dong -Sang; Maio, Vincent

    2015-10-01

    A number of waste components in US defense high level radioactive wastes (HLW) have proven challenging for current Joule heated ceramic melter (JHCM) operations and have limited the ability to increase waste loadings beyond already realized levels. Many of these “troublesome" waste species cause crystallization in the glass melt that can negatively impact product quality or have a deleterious effect on melter processing. Recent efforts at US Department of Energy laboratories have focused on understanding crystallization behavior within HLW glass melts and investigating approaches to mitigate the impacts of crystallization so that increases in waste loading can be realized. Advanced glass formulations have been developed to highlight the unique benefits of next-generation melter technologies such as the Cold Crucible Induction Melter (CCIM). Crystal-tolerant HLW glasses have been investigated to allow sparingly soluble components such as chromium to crystallize in the melter but pass out of the melter before accumulating.The Hanford site AZ-101 tank waste composition represents a waste group that is waste loading limited primarily due to high concentrations of Fe2O3 (also with high Al2O3 concentrations). Systematic glass formulation development utilizing slightly higher process temperatures and higher tolerance to spinel crystals demonstrated that an increase in waste loading of more than 20% could be achieved for this waste composition, and by extension higher loadings for wastes in the same group. An extended duration CCIM melter test was conducted on an AZ-101 waste simulant using the CCIM platform at the Idaho National Laboratory (INL). The melter was continually operated for approximately 80 hours demonstrating that the AZ-101 high waste loading glass composition could be readily processed using the CCIM technology. The resulting glass was close to the targeted composition and exhibited excellent durability in both

    Aim of the study Aim of the study was to investigate interleukin (IL)-4 serum levels in patients with advanced endometriosis and whether IL-4 promoter region (-590C/T) genetic polymorphism is involved in genetic susceptibility to endometriosis. Material and methods IL-4 serum levels and IL-4 -590C/T genetic polymorphism were determined for 80 patients with advanced endometriosis and 85 healthy fertile women using a multiplex cytokine kit, with a Luminex 200 system; high molecular weight genomic DNA was extracted from peripheral blood leukocytes, and further analyzed by PCR amplification and restriction fragment length polymorphism (PCR-PFLP). The relationship between IL-4 serum levels, genotypes and haplotypes and the presence of endometriosis was explored. Results Interleukin 4 serum levels were significantly higher in the endometriosis group compared to controls (138,459 compared to 84,710, p < 0.001). No significant difference was observed in IL-4 serum levels between genotypes. There were no differences in IL-4 -590C/T genotypes and allele frequencies between control women and patients with endometriosis (χ2 = 0.496, and χ2 = 0.928, OR = 1.3636, CI: 0.725-2.564). Conclusions The results suggest that in patients with advanced stages of endometriosis there is a higher serum level of IL-4, and that this value, or the presence of the disease, is not influenced by the presence of IL-4 -590C/T genetic polymorphism.

    The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years. PMID:26866985

    As requested by the Technical Task Request (1), a full-scale test was carried out on several different liquid-level measurement bubblers as recommended from previous testing (2). This final report incorporates photographic evidence (Appendix B) of the bubblers at different stages of testing, along with the preliminary results (Appendix C) which were previously reported (3), and instrument calibration data (Appendix D); while this report contains more detailed information than previously reported (3) the conclusions remain the same. The test was performed under highly prototypic conditions from November 26, 1996 to January 23, 1997 using the full-scale SRAT/SME tank test facilities located in the 672-T building at TNX. Two different types of advanced bubblers were subjected to approximately 58 days of slurry operation; 14 days of which the slurry was brought to boiling temperatures.The test showed that the large diameter tube bubbler (2.64 inches inside diameter) operated successfully throughout the2-month test by not plugging with the glass-frit ladened slurry which was maintained at a minimum temperature of 50 deg Cand several days of boiling temperatures. However, a weekly blow-down with air or water is recommended to minimize the slurry which builds up.The small diameter porous tube bubbler (0.62 inch inside diameter; water flow {gt} 4 milliliters/hour = 1.5 gallons/day) operated successfully on a daily basis in the glass-frit ladened slurry which was maintained at a minimum temperature of 50 degrees C and several days of boiling temperatures. However, a daily blow-down with air, or air and water, is necessary to maintain accurate readings.For the small diameter porous tube bubbler (0.62 inch inside diameter; water flow {gt} 4 milliliters/hour = 1.5 gallons/day) there were varying levels of success with the lower water-flow tubes and these tubes would have to be cleaned by blowing with air, or air and water, several times a day to maintain them plug free.

    2003-12-01

    Undergraduate involvement in research has the potential to advance science, enhance education, strengthen the research community, and raise general awareness of the importance and impact of scientific understanding. Rather than being competing objectives, these goals are synergistic. Effective research experiences are those that create win-win-win situations: benefits to the student, benefits to the project, and benefits to the scientific community. When structured appropriately, undergraduate research fits into a learner-centered paradigm that puts emphasis on student learning, rather than instructor teaching. Under such a paradigm the student and professor learn together, constructing knowledge by integrating information with critical-thinking and problem-solving skills, and use this knowledge to address issues in real-life contexts. Creating such a learning environment requires that the professor be vested in the outcome of the research, that the student take a meta-cognitive approach to the project and work at a level appropriate to her abilities, and that the student understand how her contribution fits into the project and the larger field. All of these factors lead to greater independence, confidence, and productivity on the part of the student. By providing undergraduates with these experiences, we introduce not only future scientists but also non-scientists to the excitement of discovery and the value of scientific research. Currently, we involve undergraduates in our research on the hydrology and geochemistry of a tropical montane cloud forest in Monteverde, Costa Rica. At the start of each student's involvement, we provide her with the big picture: our project goals, the relevant social issues, and the importance of watershed research. Each student then articulates her own educational and project objectives. Together, we choose tasks that match her skills and interests with our scholarly work. Specific activities range from literature review to

In 1985 Joseph W Goodman prefaced his textbook on statistical optics with a strong commitment to the ‘tools of probability and statistics’ (Goodman 2000 Statistical Optics (New York: John Wiley & Sons Inc.)) in the education of advanced optics. Since then a wide range of novel undergraduate optical counting experiments and corresponding pedagogical approaches have been introduced to underpin the rapid growth of the interest in coherence and photon statistics. We propose low cost experimental steps that are a fair way off ‘real’ quantum optics, but that give deep insight into random optical fluctuation phenomena: (1) the introduction of statistical methods into undergraduate university optical lab work, and (2) the connection between the photoelectrical signal and the characteristics of the light source. We describe three experiments and theoretical approaches which may be used to pave the way for a well balanced growth of knowledge, providing students with an opportunity to enhance their abilities to adapt the ‘tools of probability and statistics’.

    Although lactate dehydrogenase (LDH) serum levels, indirect markers of angiogenesis, are associated with a worse outcome in several tumours, their prognostic value is not defined in pancreatic cancer. Moreover, high levels are associated even with a lack of efficacy of tyrosine kinase inhibitors, contributing to explain negative results in clinical trials. We assessed the role of LDH in advanced pancreatic cancer receiving sorafenib. Seventy-one of 114 patients included in the randomised phase II trial MAPS (chemotherapy plus or not sorafenib) and with available serum LDH levels, were included in this analysis. Patients were categorized according to serum LDH levels (LDH ≤vs.> upper normal rate). A significant difference was found in progression free survival (PFS) and in overall survival (OS) between patients with LDH values under or above the cut-off (PFS: 5.2 vs. 2.7 months, p = 0.0287; OS: 10.7 vs. 5.9 months, p = 0.0021). After stratification according to LDH serum levels and sorafenib treatment, patients with low LDH serum levels treated with sorafenib showed an advantage in PFS (p = 0.05) and OS (p = 0.0012). LDH appears to be a reliable parameter to assess the prognosis of advanced pancreatic cancer patients, and it may be a predictive parameter to select patients candidate to receive sorafenib.

    2015-12-01

    The representation of URMs in the U.S. Geosciences workforce remains proportionally low compared to their representation in the general population (Bureau of Labor Sta.s.cs, 2014). Employment in this and related industries is projected to grow 32% by 2030 for minority workers (Gillula and Fullenbaum, 2014), corresponding to an additional 48,000 jobs expected to be filled by minorities (National Research Council, 2014). However, there is a shortage of employees with proper training in the hard sciences (Holeywell, 2014; Ganzglass, 2011), as well as craft skills (Hoover and Duncan, 2013), both important for middle skill employment. Industry recognizes the need for developing and retaining a diverse workforce, therefore we hightlight a program to serve as a potential vanguard initative for developing an innovative training experience for URM and underserved middle skilled workers with essential knowledge, experience and skills necessary to meet the demands of the Geosciences industry's growing need for a safe, productive and diverse workforce. Objectives are for participants to achieve the following: understanding of geosciences workforce trends and associated available opportunities; mastery of key environmental, health and safety topics; improvements in decision making skills and preparedness for responding to potential environmental, health and safety related situations; and engagement in one-on-one coaching sessions focused on resume writing, job interviewing and key "soft skills" (including conflict resolution, problem solving and critical observation, representing 3 major skills that entry- level workers typically lack.

    Brevik, Eric C.; Senturklu, Songul; Landblom, Douglas

    2015-04-01

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

  4. What Is Undergraduate Research?

    Halstead, Judith A.

    1997-12-01

    The Council on Undergraduate Research promotes and assists development of collaborative student/faculty research at primarily undergraduate colleges and universities. Most science educators today accept such research as a critical component of an undergraduate science education. Research provides the primary opportunity for students to engage in the practice of science. We can draw an analogy between sports training and the education of young scientists. We cannot train future tennis players exclusively by providing them with lectures on tennis and supervising them performing skill-development drills. To become skilled at their game, tennis players must engage in active competition. Similarly, young scientists must engage in the enterprise that affords our understanding of the physical universe. Only by participating in scientific investigation can students understand the nature of science and become scientists.

    Objective: A multisite evaluation examined the process and outcomes of Advancing Recovery, a Robert Wood Johnson Foundation initiative to overcome barriers to implementing evidence-based treatments within alcohol and drug treatment systems. Method: We report findings from a 3-year, mixed-method study of how treatment systems promoted two evidence-based practices: medication-assisted treatment and continuing care management. We compared outcomes and implementation strategies across 12 state/county agencies responsible for alcohol and drug treatment and their selected treatment centers. Each partnership received 2 years of financial and technical support to increase adoption of evidence-based treatments. Results: Partnerships flexibly applied the Advancing Recovery model to promote the adoption of evidence-based treatments. Most sites achieved a measurable increase in the numbers of patients served with evidence-based practices, up from a baseline of virtually no use. Rates of adopting medication-based treatments were higher than those for continuing care management. Partnerships used a menu of top-down and bottom-up strategies that varied in specifics across sites but shared a general process of incremental testing and piecemeal adaptation. Conclusions: Supported partnerships between providers and policymakers can achieve wider adoption of evidence-based treatment practices. Systems change unfolds through a trial-and-error process of adaptation and political learning that is unique to each treatment system. This leads to considerable state and local variation in implementation strategies and outcomes. PMID:22456246

    Qian, Xinyu; Song, Zhengbo

    2016-01-01

    Purpose Due to the rarity of thymic epithelial tumors (TET), no standard chemotherapy regimen has been identified in the relapsed setting. The aim of this study was to investigate the activity of a pemetrexed-based regimen in advanced TET as palliative treatment after failure of previous chemotherapy, and to detect its association with thymidylate synthetase (TS) level. Methods Patients with pathologically confirmed TET and treated with pemetrexed-based regimen were evaluated from 2006 to 2014 in Zhejiang Cancer Hospital. TS mRNA level was detected by real-time polymerase chain reaction. The Kaplan–Meier method was used for survival analysis. Results A total of 22 TET patients were identified, of whom eight had thymoma and 14 had thymic carcinoma. In total, the objective response rate and disease control rate of the 22 patients were 22.7% and 68.2%, respectively. Median progression-free survival and overall survival were 4.5 months and 34.9 months, respectively. A trend of lower TS mRNA levels existed in patients with disease control compared to those with progressive disease (268.0±160.5×10−4 vs 567.0±445.0×10−4, P=0.065). Conclusion Patients with advanced TET may benefit from pemetrexed-based regimen therapy. TS mRNA level is valuable for predicting the efficacy of pemetrexed in TET. PMID:27524908

    NASA Astrophysics Data System (ADS)

    1983-08-01

    An advanced lead acid storage battery was developed to the preprototype cell and module design stage. Each module is equipped with a low cost tray, automatic watering system, and air-lift pumps for increased acid circulation in each cell. With the qualified alloy catastrophic positive grid corrosion will not limit cell cycle life. An accelerated shallow cycle regime at room ambient tested 60 cell designs for the active material shedding failure mode. It is found that an antishedding active material additive reduces positive active material shedding significantly and extend the cycle life of both the positive and the negative plate. Equations relating cell design to deep cycle life are developed from the factorial tests on the 60 cells.

    2011-03-01

    Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs, few scholars have investigated the factors that affect faculty members' decisions to involve undergraduates in their research projects. We investigated the individual factors and institutional contexts that predict faculty members' likelihood of engaging undergraduates in their research project(s). Using data from the Higher Education Research Institute's 2007-2008 Faculty Survey, we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics (STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive government funding for their research are more likely to involve undergraduates in their research project(s). In addition, faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in research. Implications for advancing undergraduate research opportunities are discussed. PMID:22557706

    2016-01-01

    Electroencephalogram (EEG) is a relatively non-invasive, simple technique, and recent advances in open source analysis tools make it feasible to implement EEG as a component in undergraduate neuroscience curriculum. We have successfully led students to design novel experiments, record EEG data, and analyze event-related potentials (ERPs) during a one-semester laboratory course for undergraduates in cognitive neuroscience. First, students learned how to set up an EEG recording and completed an analysis tutorial. Students then learned how to set up a novel EEG experiment; briefly, they formed groups of four and designed an EEG experiment on a topic of their choice. Over the course of two weeks students collected behavioral and EEG data. Each group then analyzed their behavioral and ERP data and presented their results both as a presentation and as a final paper. Upon completion of the group project students reported a deeper understanding of cognitive neuroscience methods and a greater appreciation for the strengths and weaknesses of the EEG technique. Although recent advances in open source software made this project possible, it also required access to EEG recording equipment and proprietary software. Future efforts should be directed at making publicly available datasets to learn ERP analysis techniques and making publicly available EEG recording and analysis software to increase the accessibility of hands-on research experience in undergraduate cognitive neuroscience laboratory courses.

    The present study examined the reliability of student evaluations of summer undergraduate research experiences using the SURE (Survey of Undergraduate Research Experiences) and a follow-up survey disseminated 9 mo later. The survey further examines the hypothesis that undergraduate research enhances the educational experience of science undergraduates, attracts and retains talented students to careers in science, and acts as a pathway for minority students into science careers. Undergraduates participated in an online survey on the benefits of undergraduate research experiences. Participants indicated gains on 20 potential benefits and reported on career plans. Most of the participants began or continued to plan for postgraduate education in the sciences. A small group of students who discontinued their plans for postgraduate science education reported significantly lower gains than continuing students. Women and men reported similar levels of benefits and similar patterns of career plans. Undergraduate researchers from underrepresented groups reported higher learning gains than comparison students. The results replicated previously reported data from this survey. The follow-up survey indicated that students reported gains in independence, intrinsic motivation to learn, and active participation in courses taken after the summer undergraduate research experience.

    The purpose of this article is to discuss small-group apprenticeships (SGAs) as a method to instruct cell culture techniques to high school participants. The study aimed to teach cell culture practices and to introduce advanced imaging techniques to solve various biomedical engineering problems. Participants designed and completed experiments using both flow cytometry and laser scanning cytometry during the 1-month summer apprenticeship. In addition to effectively and efficiently teaching cell biology laboratory techniques, this course design provided an opportunity for research training, career exploration, and mentoring. Students participated in active research projects, working with a skilled interdisciplinary team of researchers in a large research institution with access to state-of-the-art instrumentation. The instructors, composed of graduate students, laboratory managers, and principal investigators, worked well together to present a real and worthwhile research experience. The students enjoyed learning cell culture techniques while contributing to active research projects. The institution's researchers were equally enthusiastic to instruct and serve as mentors. In this article, we clarify and illuminate the value of small-group laboratory apprenticeships to the institution and the students by presenting the results and experiences of seven middle and high school participants and their instructors.

The instructors, composed of graduate students, laboratory managers, and principal investigators, worked well together to present a real and worthwhile research experience. The students enjoyed learning cell culture techniques while contributing to active research projects. The institution's researchers were equally enthusiastic to instruct and serve as mentors. In this article, we clarify and illuminate the value of small-group laboratory apprenticeships to the institution and the students by presenting the results and experiences of seven middle and high school participants and their instructors.

    We sought to gain insight into age-related muscular limitations that may restrict the uphill walking ability of old adults. We hypothesized that: 1) old adults would exhibit smaller peak ankle joint kinetics and larger peak hip joint kinetics than young adults during both level and uphill walking and 2) these age-related differences in ankle and hip joint kinetics would be greatest during uphill vs. level walking. We quantified the sagittal plane ankle, knee, and hip joint kinetics of 10 old adults (mean ± SD, age: 72 ± 5 yrs) and 8 young adults (age: 27 ± 5 yrs) walking at 1.25 m/s on a dual-belt, force-measuring treadmill at four grades (0°, +3°, +6°, +9°). As hypothesized, old adults walked with smaller peak ankle joint kinetics (e.g., power generation: −18% at +9°) and larger peak hip joint kinetics (e.g., power generation: +119% at +9°) than young adults, most evident during the late stance phase of both level and uphill conditions. Old adults performed two to three times more single support positive work than young adults via muscles crossing the knee. In partial support of our second hypothesis, the age-related reduction in peak ankle joint moments was greater during uphill (−0.41 Nm/kg) vs. level (−0.30 Nm/kg) walking. However, old adults that exhibited reduced propulsive ankle function during level walking could perform 44% more trailing leg positive ankle joint work to walk uphill. Our findings indicate that maintaining ankle power generation and trailing leg propulsive function should be the primary focus of “prehabilitation” strategies for old adults to preserve their uphill walking ability.

    Socio-economic factors have led to an increasing trend for couples to delay parenthood. However, advancing age exerts detrimental effects upon gametes which can have serious consequences upon embryo viability. While such effects are well documented for the oocyte, relatively little is known with regard to the sperm. One fundamental role of sperm is to activate the oocyte at fertilisation, a process initiated by phospholipase C zeta (PLCζ), a sperm-specific protein. While PLCζ deficiency can lead to oocyte activation deficiency and infertility, it is currently unknown whether the expression or function of PLCζ is compromised by advancing male age. Here, we evaluate sperm motility and the proportion of sperm expressing PLCζ in 71 males (22–54 years; 44 fertile controls and 27 infertile patients), along with total levels and localisation patterns of PLCζ within the sperm head. Three different statistical approaches were deployed with male age considered both as a categorical and a continuous factor. While progressive motility was negatively correlated with male age, all three statistical models concurred that no PLCζ–related parameter was associated with male age, suggesting that advancing male age is unlikely to cause problems in terms of the sperm’s fundamental ability to activate an oocyte.

    1997-07-01

    We developed a chemistry selected topics course at Central State University, "Introduction to Laboratory Techniques in Electrochemistry" to: (1) give undergraduates hands-on experience with electrochemical measurements, (2) prepare students for summer research in Fuel Cell and Battery technology. Since students "learn by doing", the course is suitable for undergraduates from sophomore to senior levels. Students complete 6 laboratories, based on a "less is more" philosophy which emphasizes analytic and creative process rather than mandatory topical coverage. Eight electrochemical experiments are available: Construction of Zinc-Copper battery stacks, Lead Acid Battery discharge-charge cycles, Conductimetric titration of aspirin with Ammonium Hydroxide, Ion Selective Electrode determination of Fluoride in water, Cyclic Voltammetry of Potassium Ferricyanide solution, Cyclic Voltammetry of Sulfuric acid on Platinum working electrode, Anodic Stripping Voltammetry of Lead ion in solution, Differential Pulse Polarography of Lead ion in solution. Topics discussed in lecture include: chemical definitions, electrical definitions, Oxidation-Reduction reactions, Electrochemical series, Electrodes, Electrochemical Cells, direct Coulometry, electrolysis, electrochemical process efficiency, equilibrium Potentiometry, real Cell Voltages, Ion Selective Electrode types and designs, reference electrode designs, working electrode materials, pH buffers, Cyclic Voltammetry, Anodic Stripping Voltammetry, Polarography, differential pulse Polarography, and simple electrochemical instrumentation circuits.

    Reconstruction of relative sea level (RSL) has implications for investigation of crustal movements, calibration of earth rheology models and the reconstruction of ice sheets. In recent years, efforts were made to create RSL databases following a standardized methodology. These regional databases provided a framework for developing our understanding of the primary mechanisms of RSL change since the Last Glacial Maximum and a long-term baseline against which to gauge changes in sea-level during the 20th century and forecasts for the 21st. Here we present two quality-controlled Holocene RSL database compiled for North America. Along the Pacific coast of North America (British Columbia, Canada to California, USA), our re-evaluation of sea-level indicators from geological and archaeological investigations yield 841 RSL data-points mainly from salt and freshwater wetlands or adjacent estuarine sediment as well as from isolation basin. Along the Atlantic coast of North America (Hudson Bay, Canada to South Carolina, USA), we are currently compiling a database including more than 2000 RSL data-points from isolation basin, salt and freshwater wetlands, beach ridges and intratidal deposits. We outline the difficulties and solutions we made to compile databases in such different depostional environment. We address complex tectonics and the framework to compare such large variability of RSL data-point. We discuss the implications of our results for the glacio-isostatic adjustment (GIA) models in the two studied regions.

    Aims: Carbohydrate-deficient transferrin (%CDT) is a well-established and highly specific biomarker for sustained heavy consumption of alcohol. However, in pregnant women, the specificity of this biomarker might be affected by advanced gestational age, even after accounting for increased transferrin concentrations in pregnancy. The goal of this prospective study was to assess the variability in %CDT during pregnancy among alcohol-abstaining patients. Methods: Patients were recruited during one of the first prenatal care visits and followed-up to term. Abstinence was confirmed by maternal self-report and by alcohol biomarkers. Biomarkers assessed in the mother included serum gamma-glutamyltranspeptidase, urine ethyl glucuronide and ethyl sulfate, and whole blood phosphatidylethanol (PEth). In addition, PEth was measured in a dry blood spot card obtained from a newborn. For %CDT analysis, serum samples were collected at baseline and at term and analyzed by an internationally validated high-performance liquid chromatography and spectrophotometric detection method. Results: At recruitment (mean gestational age 22.6 ± 7.3 weeks), the mean %CDT concentration was 1.49 ± 0.30%, while at term, it increased to 1.67 ± 0.28% (P = 0.001). Using a conventional cutoff concentration %CDT >1.7%, 22.9 and 45.7% of the sample would be classified as ‘positive’ for this biomarker at recruitment and at term, respectively (P = 0.011 ). Conclusion: These results suggest that a conventional cutoff of 1.7% might be too low for pregnant women and would generate false-positive results. We propose that %CDT >2.0% be used as a cutoff concentration indicative of alcohol exposure in pregnant women. The sensitivity of %CDT at this cutoff for heavy drinking during pregnancy needs to be assessed further. PMID:22878591

    Recent advances involving high-throughput techniques for data generation and analysis have made familiarity with basic bioinformatics concepts and programs a necessity in the biological sciences. Undergraduate students increasingly need training in methods related to finding and retrieving information stored in vast databases. The rapid rise of bioinformatics as a new discipline has challenged many colleges and universities to keep current with their curricula, often in the face of static or dwindling resources. On the plus side, many bioinformatics modules and related databases and software programs are free and accessible online, and interdisciplinary partnerships between existing faculty members and their support staff have proved advantageous in such efforts. We present examples of strategies and methods that have been successfully used to incorporate bioinformatics content into undergraduate curricula. PMID:20810947

    Receptor for advanced glycation end products (RAGE) is a multiligand receptor of S100/calgranulins, high-mobility group box 1, and others, and it is associated with the pathogenesis of various inflammatory and circulatory diseases. The soluble form of RAGE (sRAGE) is a decoy receptor and competitively inhibits membrane-bound RAGE activation. In this study, we measured sRAGE levels in bronchoalveolar lavage fluid (BALF) of 78 patients, including 41 with interstitial pneumonia, 11 with sarcoidosis, 9 with respiratory infection, 7 with ARDS, 5 with lung cancer, and 5 with vasculitis. Among them, sRAGE was detectable in BALF of 73 patients (94%). In patients with ARDS and vasculitis, the sRAGE levels were significantly higher than in the control subjects and those with interstitial pneumonia. The sRAGE levels were positively correlated with total cell counts in BALF and serum levels of surfactant protein-D, lactate dehydrogenase, and C-reactive protein. There was an inverse correlation between PaO2/FIO2 ratio and sRAGE levels. These results indicate that sRAGE in BALF might be considered as a biomarker of lung inflammatory disorders, especially ARDS and vasculitis. PMID:27147899

    Xavier University of Louisiana leads the nation in awarding BS degrees in the biological sciences to African-American students. In this multiyear study with ∼5500 participants, data-driven interventions were adopted to improve student academic performance in a freshman-level general biology course. The three hour-long exams were common and administered concurrently to all students. New exam questions were developed using Bloom's taxonomy, and exam results were analyzed statistically with validated assessment tools. All but the comprehensive final exam were returned to students for self-evaluation and remediation. Among other approaches, course rigor was monitored by using an identical set of 60 questions on the final exam across 10 semesters. Analysis of the identical sets of 60 final exam questions revealed that overall averages increased from 72.9% (2010) to 83.5% (2015). Regression analysis demonstrated a statistically significant correlation between high-risk students and their averages on the 60 questions. Additional analysis demonstrated statistically significant improvements for at least one letter grade from midterm to final and a 20% increase in the course pass rates over time, also for the high-risk population. These results support the hypothesis that our data-driven interventions and assessment techniques are successful in improving student retention, particularly for our academically at-risk students.

    This paper reports on teachers' use of concept mapping as an alternative assessment strategy in advanced level biology classes and its effects on students' cognitive skills on selected biology concepts. Using a mixed methods approach, the study employed a pre-test/post-test quasi-experimental design involving 156 students and 8 teachers from intact classes. A researcher-constructed Biology Cognitive Skills Test was used to collect the quantitative data. Qualitative data were collected through interviews and students' personal documents. The data showed that the participants utilized concept mapping in various ways and they described positive experiences while being engaged in its use. The main challenge cited by teachers was the limited time available for more consistent use. The results showed that the use of concept mapping in advanced level biology can lead to learning gains that exceed those achieved in classes where mainly traditional methods are used. The students in the concept mapping experimental groups performed significantly better than their peers in the control group on both the lower-order (F(1) = 21.508; p < .001) and higher-order (F(1) = 42.842, p < .001) cognitive items of the biology test. A mean effect size of .56 was calculated representing the contribution of treatment to the students' performance on the test items.

    During the design of a helicopter, the weight, engine, rotor speed, and rotor geometry are given significant attention when considering the specific operations for which the helicopter will be used. However, the noise radiated from the helicopter and its relationship to the design variables is currently not well modeled with only a limited set of full-scale field test data to study. In general, limited field data have shown that reduced main-rotor advancing blade-tip Mach numbers result in reduced far-field noise levels. The status of a recent helicopter noise research project is reviewed. It is designed to provide flight experimental data which may be used to further understand helicopter main-rotor advancing blade-tip Mach number effects on far-field acoustic levels. Preliminary results are presented relative to tests conducted with a Sikorsky S-76A helicopter operating with both the rotor speed and the flight speed as the control variable. The rotor speed was operated within the range of 107 to 90 percent NR at nominal forward speeds of 35, 100, and 155 knots.

    2002-02-26

    This paper describes the results of a collaborative technology development program, sponsored by the Tanks Focus Area, to use electrochemical noise (EN) for corrosion monitoring in underground storage tanks. These tanks, made of carbon or stainless steels, contain high-level radioactive liquid waste (HLW) generated by weapons production or radioactive liquid waste from nuclear fuel reprocessing activities at several Department of Energy (DOE) sites. The term EN is used to describe low frequency fluctuations in current and voltage measurements associated with corrosion. In their most basic form, EN-based corrosion monitoring systems measure and record these fluctuations over time from electrodes immersed in the environment of interest--in this case, radioactive tank waste. The resulting EN signals have characteristic patterns for different corrosion mechanisms. In recent years, engineers and scientists from several DOE sites, in collaboration with several private companies, have conducted laboratory studies and field applications to correlate the EN signals with corrosion mechanisms active in the radioactive waste tanks. The participating DOE sites are Hanford, Savannah River, Oak Ridge Reservation and the Idaho National Engineering and Environmental Laboratory. The commercial vendors have included HiLine Engineering and Fabrication, Inc., EIC Laboratories, Inc., and AEA Technologies. Successful deployment of the EN technology will yield improved information of waste tank corrosion conditions, better tank management, and lower overall cost.

This project is focused on modeling, quantifying, and mitigating the impacts of large utility-scale PV systems (generally 1-5 MW in size) that are interconnected to the distribution system. This report discusses the concerns utilities have when interconnecting large PV systems that interconnect using PV inverters (a specific application of frequency converters). Additionally, a number of capabilities of PV inverters are described that could be implemented to mitigate the distribution system-level impacts of high-penetration PV integration. Finally, the main issues that need to be addressed to ease the interconnection of large PV systems to the distribution system are presented.

  3. Advancing reference emission levels in subnational and national REDD+ initiatives: a CLASlite approach

    PubMed Central

    2015-01-01

    Conservation and monitoring of tropical forests requires accurate information on their extent and change dynamics. Cloud cover, sensor errors and technical barriers associated with satellite remote sensing data continue to prevent many national and sub-national REDD+ initiatives from developing their reference deforestation and forest degradation emission levels. Here we present a framework for large-scale historical forest cover change analysis using free multispectral satellite imagery in an extremely cloudy tropical forest region. The CLASlite approach provided highly automated mapping of tropical forest cover, deforestation and degradation from Landsat satellite imagery. Critically, the fractional cover of forest photosynthetic vegetation, non-photosynthetic vegetation, and bare substrates calculated by CLASlite provided scene-invariant quantities for forest cover, allowing for systematic mosaicking of incomplete satellite data coverage. A synthesized satellite-based data set of forest cover was thereby created, reducing image incompleteness caused by clouds, shadows or sensor errors. This approach can readily be implemented by single operators with highly constrained budgets. We test this framework on tropical forests of the Colombian Pacific Coast (Chocó) – one of the cloudiest regions on Earth, with successful comparison to the Colombian government’s deforestation map and a global deforestation map.

    As part of an overall strategy to promote FBC coal combustion and to improve the marketability of the eastern coals, the US Department of Energy`s Morgantown Energy Research Center awarded a three level contract to Riley Stoker Corporation to develop advanced Multi Solids Fluidized Bed (MSFB) boiler designs. The first level of this contract targeted the small package boiler (10,000--50,000 lb/hr steam) and industrial size boiler (75,000--150,000 lb/hr steam) markets. Two representative sizes, 30,000 lb/hr and 110,000 lb/hr of steam, were selected for the two categories for a detailed technical and economic evaluation. Technically, both the designs showed promise, however, the advanced industrial design was favored on economic considerations. It was thus selected for further study in the second level of the contract. Results of this Level-2 effort, presented in this report, consisted of testing the design concept in Riley`s 4.4 MBtu/hr pilot MSFB facility located at Riley Research Center in Worcester, Mass. The design and economics of the proof of concept facility developed in Level-1 of the contract were then revised in accordance with the findings of the pilot test program. A host site for commercial demonstration in Level-3 of the contract was also secured. It was determined that co-firing coal in combination with paper de-inking sludge will broaden the applicability of the design beyond conventional markets. International Paper (IP), the largest paper company in the world, is willing to participate in this part of the program. IP has offered its Hammermill operation at Lockhaven, Pa, site of a future paper de-inking plant, for the proof of concept installation. This plant will go in operation in 1994. It is recommended that METC proceed to the commercial demonstration of the design developed. The approach necessary to satisfy the needs of the customer while meeting the objectives of this program is presented along with a recommended plan of action.

    Purpose To determine the most powerful cancer antigen 125 (CA125)-related prognostic factor for advanced epithelial ovarian cancer (EOC) and to identify cut-off values that distinguish patients with a poor prognosis from those with a good prognosis. Materials and Methods We included 223 patients who received staging laparotomy and were diagnosed with stage IIC–IV serous EOC. Cox regression analysis was used to determine the most significant prognostic factor among the following variables: serum CA125 before surgery and after the first, second, and sixth cycles of chemotherapy; the nadir CA125 value; the relative percentage change in CA125 levels after the first and second cycles of chemotherapy compared to baseline CA125; CA125 half-life; time to nadir; and time to normalization of the CA125 level. Results The CA125 level after the first chemotherapy cycle was the most significant independent prognostic factor for overall survival (OS). Time to normalization (p=0.028) and relative percentage change between CA125 levels at baseline and after the first chemotherapy cycle (p=0.021) were additional independent prognostic factors in terms of OS. The CA125 level after the first chemotherapy cycle (p=0.001) and time to normalization (p<0.001) were identified as independent prognostic factors for progression free survival (PFS). Conclusion Among well-established CA125-related prognostic factors, serum CA125 levels after the first cycle of chemotherapy and time to normalization were the most significant prognostic factors for both OS and PFS.

    Contemporary undergraduates in the biological sciences have unprecedented access to scientific information. Although many of these students may be savvy technologists, studies from the field of library and information science consistently show that undergraduates often struggle to locate, evaluate, and use high-quality, reputable sources of information. This study demonstrates the efficacy and pedagogical value of a collaborative teaching approach designed to enhance information literacy competencies among undergraduate biology majors who must write a formal scientific research paper. We rely on the triangulation of assessment data to determine the effectiveness of a substantial research paper project completed by students enrolled in an upper-level biology course. After enhancing library-based instruction, adding an annotated bibliography requirement, and using multiple assessment techniques, we show fundamental improvements in students' library research abilities. Ultimately, these improvements make it possible for students to more independently and effectively complete this challenging science-based writing assignment. We document critical information literacy advances in several key areas: student source-type use, annotated bibliography enhancement, plagiarism reduction, as well as student and faculty/librarian satisfaction.

    Recent efforts to incorporate computational physics in the undergraduate physics curriculum have made use of Matlab, IDL, Maple, Mathematica, Fortran, and C^1 as well as Java.^2 The benefits of similar efforts in our undergraduate physics curriculum are that students learn ways to go beyond what they learn in the classroom and use computational techniques to explore realistic physics applications. In so doing students become better prepared to perform undergraduate research that will be useful throughout their scientific careers.^3 Our standard computational physics course uses some of the above tools.^1 More recently, we have developed a first draft of a textbook for the junior level mechanics physics course that incorporates computational techniques. The text being developed in addition to employing the invaluable traditional analytical approach to problem solving, it incorporates computational physics to build on those problems. In particular, the course makes use of students abilities to use programming to go beyond the analytical approach and complement their understanding. Selected examples of representative lecture problems will be presented. ^1 ``Computation and Problem Solving in Undergraduate Physics,'' David M.

    2015-04-01

    Several studies crossing numerous disciplinary boundaries have demonstrated that undergraduate students benefit from research experiences. These benefits include personal and intellectual development, more and closer contact with faculty, the use of active learning techniques, the creation of high expectations, the development of creative and problem-solving skills, and the development of greater independence and intrinsic motivation to learn. The discipline also gains in that studies show undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program. Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline, therefore enhancing their professional socialization into their chosen field. If the goals achieved by undergraduate research include introducing these students to the advancement of their chosen field, it stands to reason the ultimate ending to this experience would be the publication of a peer-reviewed paper. While not all undergraduate projects will end with a product worthy of peer-reviewed publication, some definitely do, and the personal experience of the authors indicates that undergraduate students who achieve publication get great satisfaction and a sense of personal achievement from that publication. While a top-tier international journal probably isn't going to be the ultimate destination for many of these projects, there are several appropriate outlets. The SSSA journal Soil Horizons has published several undergraduate projects in recent years, and good undergraduate projects can often be published in state academy of science journals. Journals focused expressly on publishing undergraduate research include the Journal of Undergraduate Research and Scholarly Excellence, Reinvention, and the American Journal of Undergraduate Research.

    Background Heart failure is associated with abnormalities of myocardial structure, and plasma levels of the advanced glycation end-product (AGE) Nε-(carboxymethyl)lysine (CML) correlate with the severity and prognosis of heart failure. Aging is associated with diastolic dysfunction and increased risk of heart failure, and we investigated the hypothesis that diastolic dysfunction of aging humans is associated with altered myocardial structure and plasma AGE levels. Methods We performed histological analysis of non-ischemic left ventricular myocardial biopsies and measured plasma levels of the AGEs CML and low molecular weight fluorophores (LMWFs) in 26 men undergoing coronary artery bypass graft surgery who had transthoracic echocardiography before surgery. None had previous cardiac surgery, myocardial infarction, atrial fibrillation, or heart failure. Results The patients were aged 43–78 years and increasing age was associated with echocardiographic indices of diastolic dysfunction, with higher mitral Doppler flow velocity A wave (r = 0.50, P = 0.02), lower mitral E/A wave ratio (r = 0.64, P = 0.001), longer mitral valve deceleration time (r = 0.42, P = 0.03) and lower early diastolic peak velocity of the mitral septal annulus, e’ (r = 0.55, P = 0.008). However, neither mitral E/A ratio nor mitral septal e’ was correlated with myocardial total, interstitial or perivascular fibrosis (picrosirius red), immunostaining for collagens I and III, CML, and receptor for AGEs (RAGE), cardiomyocyte width, capillary length density, diffusion radius or arteriolar dimensions. Plasma AGE levels were not associated with age. However, plasma CML levels were associated with E/A ratio (r = 0.44, P = 0.04) and e’ (r = 0.51, P = 0.02) and LMWF levels were associated with E/A ratio (r = 0.49, P = 0.02). Moreover, the mitral E/A ratio remained correlated with plasma LMWF levels in all patients (P = 0.04) and the mitral

    Objective: To assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation. Materials and Methods: Thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. Periodontal parameters and inflammatory markers [C-reactive protein (CRP) and plasma fibrinogen] and also the white blood cell count (WBC) were evaluated prior to and four months after delivery of intensive non-surgical periodontal therapy with simultaneous lavage of chlorhexidine 0.1% from the tip of the ultrasonic instrument into the pockets. Results: Significant differences in serum CRP levels were observed four months after treatment compared to the baseline (1.85, SD=1.93 vs 2.46, SD=2.32, respectively, P<0.0001). Periodontal treatment also resulted in a significant difference in WBC and neutrophil counts compared to the baseline (P<0.0001). The reduction in fibrinogen levels was not significant at the end of the research period. Significant improvement in the pocket probing depth and clinical attachment level for pockets with initially 4–6 mm and then more than 7 mm depth was observed. Changes in plaque and bleeding scores were also statistically significant (82.75 vs. 35.84 and 19.03 vs. 1.81, respectively). Conclusion: Periodontal treatment is effective in reducing CRP levels and white blood cell count, while fibrinogen levels are not influenced by periodontal therapy. Periodontal treatment may therefore decrease the systemic inflammatory burden in patients with advanced periodontitis. PMID:21998772

    2009-01-01

    The purpose of this article is to give international readers an overview of the organisation, structure and curriculum, together with important advances and problems, of undergraduate medical education in Germany. Interest in medical education in Germany has been relatively low but has gained momentum with the new "Regulation of the Licensing of Doctors" which came into effect in 2003. Medical education had required substantial reform, particularly with respect to improving the links between theoretical and clinical teaching and the extension of interdisciplinary and topic-related instruction. It takes six years and three months to complete the curriculum and training is divided into three sections: basic science (2 years), clinical science (3 years) and final clinical year. While the reorganisation of graduate medical education required by the new "Regulation of the Licensing of Doctors" has stimulated multiple excellent teaching projects, there is evidence that some of the stipulated changes have not been implemented. Indeed, whether the medical schools have complied with this regulation and its overall success remains to be assessed systematically. Mandatory external accreditation and periodic reaccreditation of medical faculties need to be established in Germany. PMID:19675742

    LDH may represent an indirect marker of neo-angiogenesis and worse prognosis in many tumour types. We assessed the correlation between LDH and clinical outcome for biliary tract cancer (BTC) patients treated with first-line chemotherapy. Overall, 114 advanced BTC patients treated with first-line gemcitabine and cisplatin were included. Patients were divided into two groups (low vs. high LDH), according to pre-treatment LDH values. Patients were also classified according to pre- and post-treatment variation in LDH serum levels (increased vs. decreased). Median progression free survival (PFS) was 5.0 and 2.6 months respectively in patients with low and high pre-treatment LDH levels (p = 0.0042, HR = 0.56, 95% CI: 0.37–0.87). Median overall survival (OS) was 7.7 and 5.6 months (low vs. high LDH) (p = 0.324, HR = 0.81, 95% CI: 0.54–1.24). DCR was 71% vs. 43% (low vs. high LDH) (p = 0.002). In 38 patients with decreased LDH values after treatment, PFS and OS were respectively 6.2 and 12.1 months, whereas in 76 patients with post-treatment increased LDH levels, PFS and OS were respectively 3.0 and 5.1 months (PFS: p = 0.0009; HR = 0.49; 95% IC: 0.33–0.74; OS: p < 0.0001; HR = 0.42; 95% IC: 0.27–0.63). Our data seem to suggest that LDH serum level may predict clinical outcome in BTC patients receiving first-line chemotherapy. PMID:27063994

  6. The predictability of serum anti-Müllerian level in IVF/ICSI outcomes for patients of advanced reproductive age

    PubMed Central

    2011-01-01

    Background The role of serum anti-Müllerian hormone (AMH) as predictor of in-vitro fertilization outcomes has been much debated. The aim of the present study is to investigate the practicability of combining serum AMH level with biological age as a simple screening method for counseling IVF candidates of advanced reproductive age with potential poor outcomes prior to treatment initiation. Methods A total of 1,538 reference patients and 116 infertile patients aged greater than or equal to 40 years enrolled in IVF/ICSI cycles were recruited in this retrospective analysis. A reference chart of the age-related distribution of serum AMH level for Asian population was first created. IVF/ICSI patients aged greater than or equal to 40 years were then divided into three groups according to the low, middle and high tertiles the serum AMH tertiles derived from the reference population of matching age. The cycle outcomes were analyzed and compared among each individual group. Results For reference subjects aged greater than or equal to 40 years, the serum AMH of the low, middle and high tertiles were equal or lesser than 0.48, 0.49-1.22 and equal or greater than 1.23 ng/mL respectively. IVF/ICSI patients aged greater than or equal to 40 years with AMH levels in the low tertile had the highest cycle cancellation rate (47.6%) with zero clinical pregnancy. The nadir AMH level that has achieved live birth was 0.56 ng/mL, which was equivalent to the 36.4th percentile of AMH level from the age-matched reference group. The optimum cut-off levels of AMH for the prediction of nonpregnancy and cycle cancellation were 1.05 and 0.68 ng/mL, respectively. Conclusions Two criteria: (1) age greater than or equal to 40 years and (2) serum AMH level in the lowest tertile (equal or lesser than 33.3rd percentile) of the matching age group, may be used as markers of futility for counseling IVF/ICSI candidates.

  7. Persistence of undergraduate women in STEM fields

    Pedone, Maggie Helene

    The underrepresentation of women in science, technology, engineering, and mathematics (STEM) is a complex problem that continues to persist at the postsecondary level, particularly in computer science and engineering fields. This dissertation explored the pre-college and college level factors that influenced undergraduate women's persistence in STEM. This study also examined and compared the characteristics of undergraduate women who entered STEM fields and non-STEM fields in 2003-2004. The nationally representative Beginning Postsecondary Students Longitudinal Study (BPS:04/09) data set was used for analysis. BPS:04/09 study respondents were surveyed three times (NPSAS:04, BPS:04/06, BPS:04/09) over a six-year period, which enabled me to explore factors related to long-term persistence. Astin's Input-Environment-Output (I-E-O) model was used as the framework to examine student inputs and college environmental factors that predict female student persistence (output) in STEM. Chi-square tests revealed significant differences between undergraduate women who entered STEM and non-STEM fields in 2003-2004. Differences in student demographics, prior academic achievement, high school course-taking patterns, and student involvement in college such as participation in study groups and school clubs were found. Notably, inferential statistics showed that a significantly higher proportion of female minority students entered STEM fields than non-STEM fields. These findings challenge the myth that underrepresented female minorities are less inclined to enter STEM fields. Logistic regression analyses revealed thirteen significant predictors of persistence for undergraduate women in STEM. Findings showed that undergraduate women who were younger, more academically prepared, and academically and socially involved in college (e.g., lived on campus, interacted with faculty, participated in study groups, fine arts activities, and school sports) were more likely to persist in STEM

    Considering the role of carcinoembryonic antigen (CEA) serum levels as potential useful predictive marker during chemotherapy treatment, we studied its applicability in advanced non-small cell lung cancer (NSCLC) patients treated with epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs). Our retrospective cohort consists of 79 patients (33 EGFR mutated and 46 EGFR wild type or unknown) affected by advanced NSCLC, for whom CEA serum values at the beginning of TKI therapy and after the first month of treatment were available, regardless of treatment line. Baseline CEA value, percentage of CEA reduction after 1 month, and percentage of patients with ≥20 % CEA decrease after 1 month (CEA response) were correlated with disease control rate (DCR), progression-free (PFS), and overall (OS) survival, according to EGFR mutational status. Median baseline CEA levels were significantly higher in EGFR mutated (40.9 ng/ml; interquartile range (IQR) 8.9-197.6) than in wild-type cases (6.2 ng/ml; IQR 2.8-12.8; p = 0.003). Both percentage reduction in CEA levels (-10.7 vs. +13.4 %) and percentage of cases with CEA response (42 vs. 20 %) were significantly higher in mutated vs. wild-type/unknown patients (p = 0.007 and p = 0.027, respectively). In wild-type/unknown patients, CEA response was significantly correlated with DCR (p = 0.001) and resulted as a significant predictor of PFS both in univariate (p = 0.002) and in multivariate analyses (hazard ratio (HR) 0.27; 95 % confidence interval (CI) 0.11-0.66; p = 0.004); only a trend was found for OS prediction (p = 0.082). In EGFR-mutated group, CEA reduction did not show any correlation either with PFS or OS. CEA response after 1 month of EGFR-TKI therapy could be a useful marker, worthy to further studies, as early predictor of treatment outcome in EGFR wild-type/unknown unselected NSCLC cases for which no molecular predictor is yet available.

    In meeting the growing demand for graduates who have background in optical engineering,the Department of Electrical Engineering and Computer Science and the Photonics Research Center at the U.S. Military Academy have jointly developed an instructional program that familiarizes every student with principles of laser operation and provides undergraduate research opportunities in optics for electrical engineering majors and others. The program includes a series of laboratory demonstrations in the Photonics Research Center for students in all majors during their sophomore year. For electrical engineering majors, the program also offers a senior level photonics engineering course, advanced individual study in laser applications, and a variety of capstone design projects. Advanced individual study may include up to three semesters of experimental research similar to masters degree thesis work in a graduate program, while the capstone project is accomplished in one semester by design teams based on the design-build- test methodology. Both types of projects address real-world requirements specified by faculty advisors or external mentors. Our integrated approach to optics education supports ongoing state-of-the-art research in the Photonics Research Center and provides technically qualified graduates to meet the demands of the field Army of the 21st century.

    Background Infantile-onset glycogen storage disease type II (GSD-II; Pompe disease; MIM 232300) causes death early in childhood from cardiorespiratory failure in absence of effective treatment, whereas late-onset Pompe disease causes a progressive skeletal myopathy. The limitations of enzyme replacement therapy could potentially be addressed with adeno-associated virus (AAV) vector-mediated gene therapy. Methods AAV vectors containing tissue-specific regulatory cassettes, either liver-specific or muscle-specific, were administered to 12 and 17 month old Pompe disease mice to evaluate the efficacy of gene therapy in advanced Pompe disease. Biochemical correction was evaluated through GAA activity and glycogen content analyses of the heart and skeletal muscle. Western blotting, urinary biomarker, and Rotarod performance were evaluated following vector administration. Results The AAV vector containing the liver-specific regulatory cassette secreted high-level hGAA into the blood and corrected glycogen storage in the heart and diaphragm. The biochemical correction of the heart and diaphragm was associated with efficacy, as reflected by increased Rotarod performance; however, the clearance of glycogen from skeletal muscles was relatively impaired, in comparison with younger Pompe disease mice. An alternative vector containing a muscle-specific regulatory cassette transduced skeletal muscle with high efficiency, but also failed to achieve complete clearance of accumulated glycogen. Decreased transduction of the heart and liver in older mice, especially in females, was implicated as a cause for reduced efficacy in advanced Pompe disease. Conclusion The impaired efficacy of AAV vector-mediated gene therapy in old Pompe disease mice emphasized the need for early treatment to achieve full efficacy. PMID:19621331

    The APA Guidelines for the Undergraduate Psychology Major: Version 2.0 (henceforth Guidelines 2.0; APA, 2013) represents a national effort to describe and develop high-quality undergraduate programs in psychology. The task force charged with the revision of the original guidelines for the undergraduate major examined the success of the document's implementation and made changes to reflect emerging best practices and to integrate psychology's work with benchmarking scholarship in higher education. Guidelines 2.0 abandoned the original distinction drawn between psychology-focused skills and psychology skills that enhance liberal arts development. Instead, Guidelines 2.0 describes five inclusive goals for the undergraduate psychology major and two developmental levels of student learning outcomes. Suggestions for assessment planning are provided for each of the five learning goals. PMID:26866986

    Background & Aims Iron might influence severity and progression of non-hemochromatotic liver diseases. We assessed the relationships between iron, variants in HFE, and progression and outcomes using data from the HALT-C Trial. We determined whether therapy with pegylated interferon (PegIFN) affects iron variables. Methods Participants were randomly assigned to groups given long-term therapy with PegIFN (n=400) or no therapy (n=413) for 3.5 y and followed for up to 8.7 y (median 6.0 y). Associations between patient characteristics and iron variables, at baseline and over time, were made using Kaplan-Meier analyses, Cox regression models, and repeated measures analysis of covariance. Iron was detected by Prussian blue staining. Results Patients with poor outcomes (increase in Child-Turcotte-Pugh score to ≥ 7, development of ascites, encephalopathy, variceal bleeding, spontaneous bacterial peritonitis, hepatocellular carcinoma, death) had significantly higher baseline scores for stainable iron in hepatocytes and cells in portal tracts than those without outcomes. Staining for iron in portal triads correlated with lobular and total Ishak inflammatory and fibrosis scores (P<0.0001). High baseline levels of iron in triads increased the risk for poor outcome (hazard ratio=1.35, P=0.02). Iron staining decreased in hepatocytes but increased in portal stromal cells over time (P<0.0001). Serum levels of iron and total iron binding capacity decreased significantly over time (P <0.0001), as did serum ferritin (P=0.0003). Long-term therapy with PegIFN did not affect levels of iron staining. Common variants in HFE did not correlate with outcomes, including development of hepatocellular carcinoma. Conclusions Degree of stainable iron in hepatocytes and portal tract cells predicts progression and clinical and histological outcomes of patients with advanced chronic hepatitis C. Long-term therapy with low-dose PegIFN did not improve outcomes or iron variables. PMID:21335007

    1996-06-01

    In the sophomore-level Molecular Biology and Biotechnology course at Beloit College, students learn basic methods in molecular biology in the context of pursuing a semester-long original research project. We are exploring how DNA sequence affects expression levels of proteins. A DNA fragment encoding all or part of the guanylate monokinase (gmk) sequence is cloned into pSP73 and expressed in E. coli. A monoclonal antibody is made to gmk. The expression level of gmk is determined by SDS gel elctrophoresis, a Western blot, and an ELISA assay. Over four years, an increase in enrollment in the course from 9 to 34 students, the 85% of majors pursuing advanced degrees, and course evaluations all support the conclusion that involving students in research during undergraduate courses encourages them to pursue careers in science.

    Objective. To assess the prevalence and level of dental fear among health related undergraduates and to identify factors causing such fear using Kleinknecht's Dental Fear Survey (DFS) questionnaire. Methods. Kleinknecht's DFS questionnaire was used to assess dental fear and anxiety among the entire enrollment of the medical and dental undergraduates' of the University of Malaya. Results. Overall response rate was 82.2%. Dental students reported higher prevalence of dental fear (96.0% versus 90.4%). However, most of the fear encountered among dental students was in the low fear category as compared to their medical counterpart (69.2 versus 51.2%). Significantly more medical students cancelled dental appointment due to fear compared to dental students (P = 0.004). “Heart beats faster” and “muscle being tensed” were the top two physiological responses experienced by the respondents. “Drill” and “anesthetic needle” were the most fear provoking objects among respondents of both faculties. Conclusion. Dental fear and anxiety are a common problem encountered among medical and dental undergraduates who represent future health care professionals. Also, high level of dental fear and anxiety leads to the avoidance of the dental services. PMID:25386615

    α-N-acetylgalactosaminidase (nagalase) accumulates in the serum of cancer patients and its activity correlates with tumor burden, aggressiveness and clinical disease progression. The administration of GC protein-derived macrophage-activating factor (GcMAF) to cancer patients with elevated levels of nagalase has been associated with a decrease of serum nagalase activity and with significant clinical benefits. Here, we report the results of the administration of GcMAF to a heterogeneous cohort of patients with histologically diverse, advanced neoplasms, generally considered as “incurable” diseases. In most cases, GcMAF therapy was initiated at late stages of tumor progression. As this is an open-label, non-controlled, retrospective analysis, caution must be employed when establishing cause-effect relationships between the administration GcMAF and disease outcome. However, the response to GcMAF was generally robust and some trends emerged. All patients (n = 20) presented with elevated serum nagalase activity, well above normal values. All patients but one showed a significant decrease of serum nagalase activity upon weekly GcMAF injections. Decreased nagalase activity was associated with improved clinical conditions and no adverse side effects were reported. The observations reported here confirm and extend previous results and pave the way to further studies aimed at assessing the precise role and indications for GcMAF-based anticancer immunotherapy.

    Many studies have investigated the effectiveness of interventions in promoting advance directives (ADs) but there is uncertainty as to what works best, and in whom. We conducted a systematic review of the evidence in this regard, using both classical meta-analysis approaches and multi-level analyses. Eleven databases were searched for relevant reports published through March 2007. All prospective studies were eligible, whether involving a single group or several and, in the latter case, regardless of the allocation mechanism. Outcomes included formal and informal ADs assessed by chart review or self-report. Heterogeneous sets of outcomes were pooled under a random-effects model. The search yielded 55 studies, half of which targeted outpatients. Most groups of subjects were educated in a single session led by one healthcare professional. Outcomes were measured within six months of the intervention in 73% of cases. The largest set of single-arm studies yielded an overall AD completion rate of 45.6%. Across randomized trials, the largest pooled odds ratio was 4.0, decreasing to 2.6 when all comparative studies were included. Multi-variable analyses identified the provision of oral information over multiple sessions as the most successful intervention. This was true regardless of the target population. These findings support the effectiveness of educational interventions in increasing the formulation of ADs and provide practical advice on how best to achieve this goal. PMID:18644667

    During the past decade, medical imaging has made the transition from anatomical imaging to functional and even molecular imaging. Such transition provides a great opportunity to begin the integration of imaging data and various levels of biological data. In particular, the integration of imaging data and multiomics data such as genomics, metabolomics, proteomics, and pharmacogenomics may open new avenues for predictive, preventive, and personalized medicine. However, to promote imaging-omics integration, the practical challenge of imaging techniques should be addressed. In this paper, we describe key challenges in two imaging techniques: computed tomography (CT) and magnetic resonance imaging (MRI) and then review existing technological advancements. Despite the fact that CT and MRI have different principles of image formation, both imaging techniques can provide high-resolution anatomical images while playing a more and more important role in providing molecular information. Such imaging techniques that enable single modality to image both the detailed anatomy and function of tissues and organs of the body will be beneficial in the imaging-omics field. PMID:24738056

    Research experiences for undergraduates (REU) have been shown to be effective in improving undergraduate students' personal/professional development, ability to synthesize knowledge, improvement in research skills, professional advancement, and career choice. Adding to the literature on REU programs, a new conceptual model situating REU within a context of participatory action research (PAR) is presented and compared with data from a PAR-based coastal climate research experience that took place in Summer 2012. The purpose of the interdisciplinary Participatory Action Research Experiences for Undergraduates (PAREU) model is to act as an additional year to traditional, lab-based REU where undergraduate science students, social science experts, and community members collaborate to develop research with the goal of enacting change. The benefits to traditional REU's are well established and include increased content knowledge, better research skills, changes in attitudes, and greater career awareness gained by students. Additional positive outcomes are expected from undergraduate researchers (UR) who participate in PAREU, including the ability to better communicate with non-scientists. With highly politicized aspects of science, such as climate change, this becomes especially important for future scientists. Further, they will be able to articulate the relevance of science research to society, which is an important skill, especially given the funding climate where agencies require broader impacts statements. Making science relevant may also benefit URs who wish to apply their science research. Finally, URs will gain social science research skills by apprenticing in a research project that includes science and social science research components, which enables them to participate in future education and outreach. The model also positively impacts community members by elevating their voices within and outside the community, particularly in areas severely underserved

    Textron's Advanced MicroObserver(R) is a next generation remote unattended ground sensor system (UGS) for border security, infrastructure protection, and small combat unit security. The original MicroObserver(R) is a sophisticated seismic sensor system with multi-node fusion that supports target tracking. This system has been deployed in combat theaters. The system's seismic sensor nodes are uniquely able to be completely buried (including antennas) for optimal covertness. The advanced version adds a wireless day/night Electro-Optic Infrared (EOIR) system, cued by seismic tracking, with sophisticated target discrimination and automatic frame capture features. Also new is a field deployable Gateway configurable with a variety of radio systems and flexible networking, an important upgrade that enabled the research described herein. BattleHawkTM is a small tube launched Unmanned Air Vehicle (UAV) with a warhead. Using transmitted video from its EOIR subsystem an operator can search for and acquire a target day or night, select a target for attack, and execute terminal dive to destroy the target. It is designed as a lightweight squad level asset carried by an individual infantryman. Although BattleHawk has the best loiter time in its class, it's still relatively short compared to large UAVs. Also it's a one-shot asset in its munition configuration. Therefore Textron Defense Systems conducted research, funded internally, to determine if there was military utility in having the highly persistent MicroObserver(R) system cue BattleHawk's launch and vector it to beyond visual range targets for engagement. This paper describes that research; the system configuration implemented, and the results of field testing that was performed on a government range early in 2013. On the integrated system that was implemented, MicroObserver(R) seismic detections activated that system's camera which then automatically captured images of the target.

    2007-11-01

    Undergraduate research experiences have motivated many physics majors to continue their studies at the graduate level. The Department of Physics and Astronomy at SUNY Geneseo, a primarily undergraduate institution, recognizes this simple reality and is committed to ensuring research opportunities are available to interested majors beginning as early as their freshman year. Every year for more than a decade, as many as two dozen students and 8 faculty members have worked on projects related to high energy density physics and inertial confinement fusion during the summer months and the academic year. By working with their research sponsors, it has been possible to identify an impressive number of projects suitable for an institution such as Geneseo. These projects tend to be hands-on and require teamwork and innovation to be successful. They also take advantage of in-house capabilities such as the 2 MV tandem pelletron accelerator, a scanning electron microscope, a duoplasmatron ion deposition system and a 64 processor computing cluster. The end products of their efforts are utilized at the sponsoring facilities in support of nationally recognized programs. In this talk, I will discuss a number of these projects and point out what made them attractive and appropriate for an institution like Geneseo, the direct and indirect benefits of the research opportunities for the students and faculty, and how the national programs benefited from the cost-effective use of undergraduate research. In addition, I will discuss the importance of exposure for both students and faculty mentors to the larger scientific community through posters presentations at annual meetings such as the DPP and DNP. Finally, I will address the need for even greater research opportunities for undergraduate students in the future and the importance of establishing longer ``educational pipelines'' to satisfy the ever growing need for top-tier scientists and engineers in industry, academia and the

  18. An Investigation to Advance the Technology Readiness Level of the Centaur Derived On-orbit Propellant Storage and Transfer System

    NASA Astrophysics Data System (ADS)

    Silvernail, Nathan L.

    This research was carried out in collaboration with the United Launch Alliance (ULA), to advance an innovative Centaur-based on-orbit propellant storage and transfer system that takes advantage of rotational settling to simplify Fluid Management (FM), specifically enabling settled fluid transfer between two tanks and settled pressure control. This research consists of two specific objectives: (1) technique and process validation and (2) computational model development. In order to raise the Technology Readiness Level (TRL) of this technology, the corresponding FM techniques and processes must be validated in a series of experimental tests, including: laboratory/ground testing, microgravity flight testing, suborbital flight testing, and orbital testing. Researchers from Embry-Riddle Aeronautical University (ERAU) have joined with the Massachusetts Institute of Technology (MIT) Synchronized Position Hold Engage and Reorient Experimental Satellites (SPHERES) team to develop a prototype FM system for operations aboard the International Space Station (ISS). Testing of the integrated system in a representative environment will raise the FM system to TRL 6. The tests will demonstrate the FM system and provide unique data pertaining to the vehicle's rotational dynamics while undergoing fluid transfer operations. These data sets provide insight into the behavior and physical tendencies of the on-orbit refueling system. Furthermore, they provide a baseline for comparison against the data produced by various computational models; thus verifying the accuracy of the models output and validating the modeling approach. Once these preliminary models have been validated, the parameters defined by them will provide the basis of development for accurate simulations of full scale, on-orbit systems. The completion of this project and the models being developed will accelerate the commercialization of on-orbit propellant storage and transfer technologies as well as all in

    Soil contaminated with hydrocarbons is a current problem of great importance. These contaminants may be toxic, can retain water and block gas exchange with the atmosphere, which produces a poor-quality soil unsuitable for ecological health. Electroremediation is among the treatments for the removal of such contaminants. In this research, a pilot-level electroremediation test was applied using a circular arrangement of electrodes with a Ti cathode at the middle of the cell surrounded by six IrO2-Ta2O5 | Ti anodes. The presence of an NaOH electrolyte helps to develop the electromigration and electro-osmosis of gasoline molecules (at 1126 mg kg-1) surrounded by Na+ ions. The hydrocarbons are directed towards the cathode and subsequently removed in an aqueous Na+ - hydrocarbon solution, and the -OH migrates to the anode. During electrokinetic treatment, the physicochemical characteristics of the soil close to either the cathode or anode and at the half-cell were evaluated during the three weeks of treatment. During that time, more than 80% of hydrocarbons were removed. Hydrocarbons removed by the electrokinetic treatment of gasoline-polluted soil were collected in a central wastewater compartment and subsequently treated with a Fenton-type advanced oxidation process. This achieved more than 70% mineralization of the hydrocarbons to CO2 and H2O within 1.5 h; its low toxicity status was verified using the Deltatox® kit test. With this approach, the residual water complied with the permissible limits of COD, pH, and electrical conductivity for being discharged into water bodies, according to Mexican norm NOM-001-SEMARNAT-1996.

    Augmentation of potable water sources by planned indirect potable reuse of wastewater is being widely considered to address growing water shortages. Environmental buffers such as lakes and dams may act as one of a series of barriers to potable water contamination stemming from micropollutants in wastewater. In South-East Queensland, Australia, current government policy is to begin indirect potable reuse of water from reverse osmosis equipped advanced water treatment plants (AWTPs) when the combined capacity of its major storages is at 40% capacity. A total of 15 organic contaminants including NDMA and bisphenol A have been publically reported as detected in recycled water from one of South-East Queensland's AWTPs, while another 98 chemicals were analysed for, but found to be below their detection limit. To assess the natural attenuation in Lake Wivenhoe, a Level III fugacity based evaluative fate model was constructed using the maximum concentrations of these contaminants detected as input data. A parallel aquivalence based model was constructed for those contaminants, such as dichloroacetic acid, dalapon and triclopyr, which are ionised in the environment of Lake Wivenhoe. A total of 247 organic chemicals of interest, including disinfection by-products, pesticides, pharmaceuticals and personal care products, xenoestrogens and industrial chemicals, were evaluated with the model to assess their potential for natural attenuation. Out of the 15 detected chemicals, trihalomethanes are expected to volatilise with concentrations in the outflow from the dam approximately 400 times lower than influent from the AWTPs. Transformation processes in water are likely to be more significant for NDMA and pharmaceuticals such as salicylic acid and paracetamol as well as for caffeine and the herbicides dalapon and triclopyr.

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 19 institutions founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. The collaborative nature of the UAT allows faculty and students from a wide ​range of public and private colleges and especially those with small astronomy programs to develop scholarly collaborations. Components of the program include an annual undergraduate workshop at Arecibo Observatory, observing runs at Arecibo, computer infrastructure, summer and academic year research projects, and dissemination at national meetings (e.g., Alfvin et al., Martens et al., Sanders et al., this meeting). Through this model, faculty and students are learning how science is accomplished in a large collaboration while contributing to the scientific goals of a major legacy survey. In the 7 years of the program, 23 faculty and more than 220 undergraduate students have participated at a significant level. 40% of them have been women and members of underrepresented groups. Faculty, many of whom were new to the collaboration and had expertise in other fields, contribute their diverse sets of skills to ALFALFA ​related projects via observing, data reduction, collaborative research, and research with students. 142 undergraduate students have attended the annual workshops at Arecibo Observatory, interacting with faculty, graduate students, their peers, and Arecibo staff in lectures, group activities, tours, and observing runs. Team faculty have supervised 131 summer research projects and 94 academic year (e.g., senior thesis) projects. 62 students have traveled to Arecibo Observatory for observing runs and 46 have presented their results at national meetings. 93% of alumni are attending graduate school and/or pursuing a career in STEM. Half of those pursuing graduate degrees in Physics or Astronomy are women. This work has been

    The highly interdisciplinary field of bioinformatics has emerged as a powerful modern science. There has been a great demand for undergraduate- and graduate-level trained bioinformaticists in the industry as well in the academia. In order to address the needs for trained bioinformaticists, its curriculum must be offered at the undergraduate level, especially at four-year colleges, where a majority of the United States gets its education. There are many challenges in developing an undergraduate-level bioinformatics program that needs to be carefully designed as a well-integrated and cohesive interdisciplinary curriculum that prepares the students for a wide variety of career options. This article describes the challenges of establishing a highly interdisciplinary undergraduate major, the development of an undergraduate bioinformatics degree program at Ramapo College of New Jersey, and lessons learned in the last 10 years during its management.

    Weber, Carolyn F

    2016-01-01

    Western science has grown increasingly reductionistic and, in parallel, the undergraduate life sciences curriculum has become disciplinarily fragmented. While reductionistic approaches have led to landmark discoveries, many of the most exciting scientific advances in the late 20th century have occurred at disciplinary interfaces; work at these interfaces is necessary to manage the world's looming problems, particularly those that are rooted in cellular-level processes but have ecosystem- and even global-scale ramifications (e.g., nonsustainable agriculture, emerging infectious diseases). Managing such problems requires comprehending whole scenarios and their emergent properties as sums of their multiple facets and complex interrelationships, which usually integrate several disciplines across multiple scales (e.g., time, organization, space). This essay discusses bringing interdisciplinarity into undergraduate cellular biology courses through the use of multiscalar topics. Discussing how cellular-level processes impact large-scale phenomena makes them relevant to everyday life and unites diverse disciplines (e.g., sociology, cell biology, physics) as facets of a single system or problem, emphasizing their connections to core concepts in biology. I provide specific examples of multiscalar topics and discuss preliminary evidence that using such topics may increase students' understanding of the cell's position within an ecosystem and how cellular biology interfaces with other disciplines.

    Pressures from students and teachers, from professional bodies, and from changes in the way health care is delivered are all forcing a rethink of how medical students should be taught. These pressures may be more intense in London but are not confined to it. The recommendation the Tomlinson report advocates that has been generally welcomed is for more investment in primary care in London. General practitioners have much to teach medical schools about effective ways of learning, but incentives for teaching students in general practice are currently low, organising such teaching is difficult and needs resources, and resistance within traditional medical school hierarchies needs to be overcome. Likewise, students value learning within local communities, but the effort demanded of public health departments and community organisations is great at a time when they are under greater pressure than ever before. The arguments over research that favour concentration in four multifaculty schools are less clear cut for undergraduate education, where personal support for students is important. An immediate concern is that the effort demanded for reorganising along the lines suggested by Tomlinson will not leave medical schools much energy for innovating. Images p259-a PMID:8499026

    Spiegelberg, Bryan D

    2014-01-01

    Encouraging undergraduate students to access, read, and analyze current primary literature can positively impact learning, especially in advanced courses. The incorporation of literature into coursework typically involves reading and responding to full research reports. Such exercises have clear value as students make connections between experiments and are able to probe and critique scientific logic. The exclusive use of full papers, though, may reinforce certain students' tendencies to rely on textual clues rather than a critical analysis of the actual data presented. I propose that structured activities requiring students to focus on individual parts of research papers, even on a single figure, are beneficial in a literature-centered advanced undergraduate course, because they promote the deep reading that is critical to scientific discourse. In addition, I describe how one such focused assignment boosted learning and was well received by students in a second-semester biochemistry course. PMID:24243802

    Since the introduction of the Welsh Baccalaureate Advanced Diploma Qualification (WBQ) in 2003, an increasing number of students are applying to higher education institutions (HEIs) with this qualification. The advanced-level WBQ is regarded as equivalent to one General Certificate of Education A-Level (GCE A-Level). This study assesses the impact of attaining the WBQ in addition to three GCE A-Levels on overall university degree performance in comparison to attaining four GCE A-Levels, in three cohorts of undergraduate students (Year 1 = 318, Year 2 = 280, Year 3 = 236) studying Biosciences from 2005 to 2011 at a UK HEI. Binary logistic regression was used to compare the academic attainment of students who had achieved four GCE A-Levels to those who had achieved three GCE A-Levels in addition to the WBQ. Comparisons were also made between students who had achieved three GCE A-Levels and those who had achieved three GCE A-Levels in addition to the WBQ. The results suggest that students who achieved the WBQ qualification in its current form, in addition to three GCE A-Levels, performed less well academically in undergraduate studies than those who achieved four GCE A-Levels. Furthermore, this effect was still present when the balance between coursework and examination was considered, and when students who had achieved the WBQ in addition to three GCE A-Levels were compared to students who had achieved three GCE A-Levels.

    Erlotinib is a low molecular weight tyrosine kinase inhibitor (TKI) directed at epidermal growth factor receptor (EGFR), widely used in the treatment of locally advanced or metastatic-stage non-small cell lung cancer (NSCLC). Although introduction of EGFR-TKIs have significantly extended survival of advanced-stage NSCLC patients, their efficacy in the entire patient population is relatively low. Aside from activating EGFR mutations, no reliable biochemical or molecular predictors of response to erlotinib have been established. The aim of our retrospective study was to evaluate the association of baseline serum levels of C-reactive protein (CRP) with outcomes in patients with advanced-stage NSCLC treated with erlotinib. We retrospectively analyzed clinical data of 595 patients with advanced-stage NSCLC (IIIB or IV) treated with erlotinib. Serum CRP was measured using an immunoturbidimetric method. High baseline levels of CRP (≥10 mg/l) were measured in 387 (65 %) patients, and normal levels (<10 mg/l) were measured in 208 (35 %) patients. The median progression-free survival (PFS) and overall survival (OS) for patients with high CRP was 1.8 and 7.7 compared to 2.8 and 14.4 months for patients with low CRP (p < 0.001 and p < 0.001). The multivariable Cox proportional hazards model revealed that CRP was significantly associated with PFS and also with OS (hazard ratio (HR) = 1.57, p < 0.001, and HR = 1.63, p < 0.001, respectively). In conclusion, the results of the conducted retrospective study suggest that high baseline level of CRP was independently associated with worse outcome of patients with advanced-stage NSCLC treated with erlotinib. CRP is a commonly used biomarker which is simple and easy to detect, and thus, it is feasible for the use in the routine clinical practice. PMID:26088452

  20. Scientific education curricular reforms for undergraduate programs of higher education in Puerto Rico: 1995--2005

    Pena-Carrion, Zulma M.

    The knowledge society requires the acquisition of certain competencies for the development of social capital; some of these competencies are related to the development of a scientific culture. This qualitative research was carried out through a descriptive case study that analyzed, compared and contrasted the curricular reform processes and institutional policies modifications that occurred in undergraduate level programs of two higher education institutions in Puerto Rico. Modifications established between 1995 and 2005 were included in the research, with particular interest on changes affecting the undergraduate profile, as related to the development of a scientific culture. The theoretical framework used included the identification of general competencies related to the development of a scientific culture. Through qualitative content analysis of official and public documents of each participating institution a determination was made on the existence or absence of the general competencies previously identified and established. The development of a scientific culture was not an institutional goal in any of the participating institutions. No direct evidence was found that institutional policies existed toward the development of a scientific culture. Competencies related to the theoretical framework used by this research were found in some of the institutional goals and in General Education courses. The General Education component was identified as a common or core curriculum in all undergraduate programs; its purpose was the development in students of the general competencies and characteristics that favor the acquisition of an integrated education in individuals. The research found that one of the participating institutions included, within the General Education component, the general competencies that are directly related to the development of a scientific culture. The creation of a scientific culture, and its development and contribution, will depend upon

    The purpose of this study was to examine the relationship between hematopoietic cell transplant candidate and proxy advance care planning (ACP) behavior and attitudes. A total of 49 candidates and 44 proxies completed the Advance Directive Attitudes Survey, Multidimensional Health Locus of Control Scale, Family Decision Making Self-Efficacy Scale, and the State-Trait Anxiety Inventory. In all, 45% of candidates reported completing an advance directive (AD), while only 26% had ADs on file; 80% of candidates discussed ACP wishes with their loved ones and 15% discussed ACP wishes with their medical team. The AD completers were significantly (1) older, (2) more positive about ADs, and (3) were less likely to believe that health events happen by chance. Discrepancies between reported ACP behavior and communication with health care practitioners have implications for end-of-life care. PMID:23946253

    Over the past decade, the development of infrared focal plane arrays (FPAs) has seen two trends: decreasing of the pixel size and increasing of signal-processing capability at the device level. Enabling more capability within smaller pixels can be achieved through the use of advanced wafer-level processes for the integration of FPAs with silicon (Si) readout integrated circuits (ROICs). In this paper, we review the development of these wafer-level integration technologies, highlighting approaches in which the infrared sensor is integrated with three-dimensional ROIC stacks composed of multiple layers of Si circuitry interconnected using metal-filled through-silicon vias.

    2008-07-01

    This article reports on a theme emerging from a focused ethnography examining the professional socialization of undergraduate fourth year nursing students during a rural hospital preceptored clinical experience. Nursing students and preceptors geographically dispersed over a 640,000 square kilometer rural area participated in this study. Students report student preparedness for the rural hospital setting means to "know what you are getting into". Assisting nursing students to prepare for the rural hospital preceptorship facilitates a positive experience thus increasing the effectiveness of the preceptorship model of clinical teaching. Having a positive rural-based experience also has the potential for recruiting new staff. These preliminary findings suggest that student preparation for the rural hospital preceptorship includes cognitive and psychological preparation, as well as the acquisition of common advanced clinical skills.

    Protein and amine halogenation is a type of oxidative stress induced by phagocytic overstimulation, and its role in Parkinson's disease (PD) has not been discerned. We have detected that advanced oxidized protein products, markers of protein halogenation, are reliably enhanced in serum of patients with PD (n=60) relative to control subjects (n=45, p<0.012), and to a lesser extent in the cerebrospinal fluid. Amine halogenation, as evaluated through 3-chlorotyrosine, is not affected. Mieloperoxidase and hydrogen peroxide levels, halogenative factors of phagocytes, are devoid of changes. Levels of advanced oxidized protein products are progressively reduced over time, and the duration of PD is larger in the Hoehn-Yahr-stage-2/3 patients (n=34) with low serum levels (R(2)=0.0145, p<0.003). Levodopa treatment contributes to this reduction (R(2)=0.259, p<0.001). These protein products are not cytotoxic, unlike 3-chlorotyrosine, but they are known to form inflammatory mediators after conjugation with serum albumin. Our observations lead to the hypothesis that the serum level of advanced oxidized protein products is a prognostic marker of PD duration, and these oxidized proteins could participate in the development of parkinsonian neurodegeneration.

    Purpose To conduct analyses exploring trial-level and patient-level associations between overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) in advanced non–small-cell lung cancer (NSCLC) trials. Methods We identified 14 trials (N = 12,567) submitted to US Food and Drug Administration since 2003 of treatments for advanced NSCLC. Only randomized, active-controlled trials with more than 150 patients were included. Associations between trial-level PFS hazard ratio (HR), OS HR, and ORR odds ratio were analyzed using a weighted linear regression model. Patient-level responder analyses comparing PFS and OS between patients with and without an objective response were performed using pooled data from all studies. Results In the trial-level analysis, the association between PFS and ORR was strong (R2 = 0.89; 95% CI, 0.80 to 0.98). There was no association between OS and ORR (R2 = 0.09; 95% CI, 0 to 0.33) and OS and PFS (R2 = 0.08; 95% CI, 0 to 0.31). In the patient-level responder analyses, patients who achieved a response had better PFS and OS compared with nonresponders (PFS: HR, 0.40; 95% CI, 0.38 to 0.42; OS: HR, 0.40; 95% CI, 0.38 to 0.43). Conclusion On a trial level, there is a strong association between ORR and PFS. An association between ORR and OS and between PFS and OS was not established, possibly because of cross-over and longer survival after progression in the targeted therapy and first-line trials. The patient-level analysis showed that responders have a better PFS and OS compared with nonresponders. A therapy in advanced NSCLC with a large magnitude of effect on ORR may have a large PFS effect. PMID:25667291

    Clinical pharmacy is currently not practised in Namibia. To introduce the concept and skills pertinent to this area of practice, pharmacy undergraduates at Namibia's new School of Pharmacy are introduced to clinical pharmacy from their second year, and progress from theory to practical application on the wards. This approach has led to students having a greater understanding of clinical pharmacy and how it can be applied in practice. Introducing clinical pharmacy progressively at an undergraduate level may help to stimulate interest in the speciality for future career progression. PMID:25854309

In our second project, we are constructing our own microcontrollers to work as a general-purpose interface based off work carried out in Review of Scientific Instruments 84, 103101 (2013). It was designed for low cost and simple construction, making it ideal for undergraduate level work. This circuit has room for two interchangeable daughter boards, giving it the capability to work as a general lab interface, lock-in detector, or waveform generator.

  5. Constructing Dual Beam Optical Tweezers for Undergraduate Biophysics Research

    NASA Astrophysics Data System (ADS)

    Daudelin, Brian; West-Coates, Devon; Del'Etoile, Jon; Grotzke, Eric; Paramanathan, Thayaparan

    Optical tweezing, or trapping, is a modern physics technique which allows us to use the radiation pressure from laser beams to trap micron sized particles. Optical tweezers are commonly used in graduate level biophysics research but seldom used at the undergraduate level. Our goal is to construct a dual beam optical tweezers for future undergraduate biophysical research. Dual beam optical tweezers use two counter propagating laser beams to provide a stronger trap. In this study we discuss how the assembly of the dual beam optical tweezers is done through three main phases. The first phase was to construct a custom compressed air system to isolate the optical table from the vibrations from its surroundings so that we can measure pico-newton scale forces that are observed in biological systems. In addition, the biomaterial flow system was designed with a flow cell to trap biomolecules by combining several undergraduate semester projects. During the second phase we set up the optics to image and display the inside of the flow cell. Currently we are in the process of aligning the laser to create an effective trap and developing the software to control the data collection. This optical tweezers set up will enable us to study potential cancer drug interactions with DNA at the single molecule level and will be a powerful tool in promoting interdisciplinary research at the undergraduate level.

  1. Theory and practice: Science for undergraduates of limited English proficiency

    NASA Astrophysics Data System (ADS)

    Rosenthal, Judith W.

    1993-06-01

    Between 1980 and 1990, the total number of Asian, Hispanic, American Indian, and foreign undergraduates increased by more than 50% at public and private, four-year and two-year colleges. Many of these students may be of limited English proficiency, suggesting that the traditional science lecture/lab format may need modification to incorporate the theory of second language acquisition as it pertains to the practice of content instruction. Various methods exist to improve science instruction for limited English proficient undergraduates. These included the adjunct and tutorial models, sheltered or bridge science instruction, faculty development, and science instruction in the students' native language. Any plan for science education reform at the collegiate level or for increasing minority participation in science must address the needs of the growing population of undergraduates who speak English as a second language.

  2. Thermodynamics in Context: A Case Study of Contextualized Teaching for Undergraduates

    NASA Astrophysics Data System (ADS)

    Holman, John; Pilling, Gwen

    2004-03-01

    Thermodynamics is often considered to be a dry and theoretical area of undergraduate chemistry. To make it more accessible, a contextualized approach to first-year university thermodynamics has been developed, building on the experiences at the high school level of ChemCom in the United States and Salters Advanced Chemistry in the United Kingdom. A constructivist approach takes into account students' prior understanding of enthalpy and energy transfer from high school chemistry. Contextualized lectures, tutorials, workshops, and examination questions are supported by a bank of Web-based questions designed to practice the basic mathematical manipulations. Contexts used include fuels, explosives, food, and bioenergetics. The course, which is aimed at chemistry majors, has been used at the University of Leeds and the University of York in the United Kingdom. Initial evaluation suggests that the approach increases the appeal of thermodynamics and improves learning of fundamental principles. The article seeks responses from other instructors who are interested in bringing the benefits of contextualized teaching to undergraduate chemistry.

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 19 institutions founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. In this talk we present outcomes for the more than 250 undergraduate students who have who have participated in the program during the 8 years of funding. 40% of these students have been women and members of underrepresented groups. To date 148 undergraduate students have attended annual workshops at Arecibo Observatory, interacting with faculty, graduate students, their peers, and Arecibo staff in lectures, group activities, tours, and observing runs. Team faculty have supervised 159 summer research projects and 120 academic year (e.g., senior thesis) projects. 68 students have traveled to Arecibo Observatory for observing runs and 55 have presented their results at national meetings such as the AAS. Through participation in the UAT, students are made aware of career paths they may not have previously considered. More than 90% of alumni are attending graduate school and/or pursuing a career in STEM. 42% of those pursuing graduate degrees in Physics or Astronomy are women.

  6. Undergraduate Biocuration: Developing Tomorrow's Researchers While Mining Today's Data.

    PubMed

    Mitchell, Cassie S; Cates, Ashlyn; Kim, Renaid B; Hollinger, Sabrina K

    2015-01-01

    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week. PMID:26557796

    2015-01-01

    The traditional undergraduate program of study incorporates a selection of classes that represent a broad spectrum of subdisciplines. Unfortunately, few curricula successfully integrate concepts in all subdisciplines, giving undergraduates the misconception that there is a lack of application or connectedness between class subjects. An integrated course-embedded research experience (ICURE) was initiated to redress this problem by bridging classes within one discipline in an effort to engage undergraduates in a long-term analysis of biodiversity. The approach was both inclusive and longitudinal: 1) the ICURE bridge brought students from different classes and levels of instruction together with faculty members in a research project with a common goal—chronicling the changing face of the local environment in biological terms; and 2) research data collected were maintained and supplemented each semester and year in an online biodiversity database. Analysis of content and attitudinal gains suggested the integrated research protocol increased student comprehension and confidence. Results are discussed in terms of future amendments to instructional design and potential research applications. Though this program was concentrated on one discipline, there is no reason to assume other disciplines could not take advantage of similar research connections. PMID:25681416

    2010-01-01

    Initial results from a major study of scientific literacy are presented, involving nearly 10,000 undergraduates in science classes at a large Southwestern Land Grant public university over a 20-year period. The science content questions overlap with those in the NSF's Science Indicators series. About 10% of all undergraduates in the US take a General Education astronomy course, and NSF data and the work of Jon Miller show that the number of college science courses taken is the strongest predictor of civic scientific literacy. Our data show that gains in knowledge on any particular item through the time students graduate are only 10-15%. Among students who have taken most or all of their science requirements, one-in-three think that antibiotics kill viruses as well as bacteria, one-in-four think lasers work by focusing sound waves, one-in-five think atoms are smaller than electrons, and the same fraction is unaware that humans evolved from earlier species of animals and that the Earth takes a year to go around the Sun. The fraction of undergraduates saying that astrology is "not at all” scientific increases from 17% to a still-low 34% as they move through the university. Equally worrying, half of all science majors say that astrology is "sort of” or "very” scientific. Education majors - the cohort of future teachers - perform worse than average on most individual questions and in terms of their overall scientific literacy. Assuming the study institution is representative of the nation's higher education institutions, our instruction is not raising students to the level we would expect for educated citizens who must vote on many issues that relate to science and technology. We acknowledge the NSF for funding under Award No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS) Program.

  14. Advanced methods for modeling water-levels and estimating drawdowns with SeriesSEE, an Excel add-in

    USGS Publications Warehouse

    Halford, Keith; Garcia, C. Amanda; Fenelon, Joe; Mirus, Benjamin B.

    2012-01-01

    Water-level modeling is used for multiple-well aquifer tests to reliably differentiate pumping responses from natural water-level changes in wells, or “environmental fluctuations.” Synthetic water levels are created during water-level modeling and represent the summation of multiple component fluctuations, including those caused by environmental forcing and pumping. Pumping signals are modeled by transforming step-wise pumping records into water-level changes by using superimposed Theis functions. Water-levels can be modeled robustly with this Theis-transform approach because environmental fluctuations and pumping signals are simulated simultaneously. Water-level modeling with Theis transforms has been implemented in the program SeriesSEE, which is a Microsoft® Excel add-in. Moving average, Theis, pneumatic-lag, and gamma functions transform time series of measured values into water-level model components in SeriesSEE. Earth tides and step transforms are additional computed water-level model components. Water-level models are calibrated by minimizing a sum-of-squares objective function where singular value decomposition and Tikhonov regularization stabilize results. Drawdown estimates from a water-level model are the summation of all Theis transforms minus residual differences between synthetic and measured water levels. The accuracy of drawdown estimates is limited primarily by noise in the data sets, not the Theis-transform approach. Drawdowns much smaller than environmental fluctuations have been detected across major fault structures, at distances of more than 1 mile from the pumping well, and with limited pre-pumping and recovery data at sites across the United States. In addition to water-level modeling, utilities exist in SeriesSEE for viewing, cleaning, manipulating, and analyzing time-series data.
