Teaching schools as teacher education laboratories

Directory of Open Access Journals (Sweden)

Sarah Gravett

2017-12-01

Full Text Available This study emanated from the Integrated Strategic Planning Framework for Teacher Education and Development in South Africa. This Framework proposes that teaching schools should be established in the country to improve the teaching practicum component of pre-service teacher education. A generic qualitative study was undertaken to explore the affordances of a teaching school to enable student teacher learning for the teaching profession. The overarching finding of the study is that a teaching school holds numerous affordances for enabling meaningful student teacher learning for the teaching profession. However, the full affordances of a teaching school will not be realised if a teaching school is viewed merely as a practicum site. Foregrounding a laboratory view of practice work in a teaching school could enable true research-oriented teacher education. A teaching school as a teacher education laboratory would imply a deliberate inclusion of cognitive apprenticeship and an inquiry orientation to learning in the schoo

Modern dentistry and dental education in China were first introduced from abroad by Dr. Lindsay in 1907. However, advancements in the field of dental laboratory technology did not occur to the same degree in specialties such as prosthodontics and orthodontics. Since the 1990s, orders from abroad demanding dental appliances surged as the image of China as the "world's factory" strengthened. The assembly line model, in which technicians work like simple procedure workers, was rapidly applied to denture production, while the traditional education system and apprenticeship systems demonstrated little progress in these years. The lack of advancement in dental laboratory technology education caused insufficient development in China's dental technology industry. In order to alter the situation, a four-year dental laboratory technology undergraduate educational program was established in 2005 by West China School of Stomatology, Sichuan University (WCSS, SCU). This program was based on SCU's undergraduate education and WCSS's junior college education systems. The program introduced scientific methods in relevant subjects into laboratory technicians' training and made many improvements in the availability of trained faculty, textbooks, laboratory facilities, and curriculum.

The Southwest Surety Institute includes Arizona State University (ASU), Louisiana State University (LSU), New Mexico Institute of Mining and Technology (NM Tech), New Mexico State University (NMSU), and Sandia National Laboratories (SNL). The universities currently offer a full spectrum of post-secondary programs in security system design and evaluation, including an undergraduate minor, a graduate program, and continuing education programs. The programs are based on the methodology developed at Sandia National Laboratories over the past 25 years to protect critical nuclear assets. The programs combine basic concepts and principles from business, criminal justice, and technology to create an integrated performance-based approach to security system design and analysis. Existing university capabilities in criminal justice (NMSU), explosives testing and technology (NM Tech and LSU), and engineering technology (ASU) are leveraged to provide unique science-based programs that will emphasize the use of performance measures and computer analysis tools to prove the effectiveness of proposed systems in the design phase. Facility managers may then balance increased protection against the cost of implementation and risk mitigation, thereby enabling effective business decisions. Applications expected to benefit from these programs include corrections, law enforcement, counter-terrorism, critical infrastructure protection, financial and medical care fraud, industrial security, and border security.

Clinical skills laboratories have been established in medical institutions as facilities for simulation-based medical education (SBME). SBME is believed to be superior to the traditional style of medical education from the viewpoint of the active and adult learning theories. SBME can provide a learning cycle of debriefing and feedback for learners as well as evaluation of procedures and competency. SBME offers both learners and patients a safe environment for practice and error. In a full-environment simulation, learners can obtain not only technical skills but also non-technical skills, such as leadership, team work, communication, situation awareness, decision-making, and awareness of personal limitations. SBME is also effective for integration of clinical medicine and basic medicine. In addition, technology-enhanced simulation training is associated with beneficial effects for outcomes of knowledge, skills, behaviors, and patient-related outcomes. To perform SBME, effectively, not only simulators including high-fidelity mannequin-type simulators or virtual-reality simulators but also full-time faculties and instructors as professionals of SBME are essential in a clinical skills laboratory for SBME. Clinical skills laboratory is expected to become an integrated medical education center to achieve continuing professional development, integrated learning of basic and clinical medicine, and citizens' participation and cooperation in medical education.

Changing Educational Traditions with the Change Laboratory

Directory of Open Access Journals (Sweden)

Louis Royce Botha

2017-07-01

Full Text Available This paper outlines the use of a form of research intervention known as the Change Laboratory to illustrate how the processes of organisational change initiated at a secondary school can be applied to develop tools and practices to analyse and potentially re-make educational traditions in a bottom-up manner. In this regard it is shown how a cultural-historical activity theory (CHAT perspective can be combined with a relational approach to generate the theoretical and practical tools for managing change at a school. Referring to an ongoing research project at a school, the paper describes how teachers and management there, with the aid of the researcher, attempt to re-configure their educational praxis by drawing on past, present and future scenarios from their schooling activity. These are correlated with similarly historically evolving theoretical models and recorded empirical data using the Vygotskyian method of double stimulation employed by the Change Laboratory. A relational conceptualisation of the school’s epistemological, pedagogical and organisational traditions is used to map out the connections between various actors, resources, roles and divisions of labour at the school. In this way the research intervention proposes a model of educational change that graphically represents it as a network of mediated relationships so that its artefacts, practices and traditions can be clearly understood and effectively manipulated according to the shared objectives of the teachers and school management. Such a relationally-oriented activity theory approach has significant implications in terms of challenging conventional processes of educational transformation as well as hegemonic knowledge-making traditions themselves.

Full Text Available Background: There is a worldwide shortage of qualified laboratory personnel to provide adequate testing for the detection and monitoring of diseases. In an effort to increase laboratory capacity in developing countries, new skills have been introduced into laboratory services. Curriculum revision with a focus on good laboratory practice is an important aspect of supplying entry-level graduates with the competencies needed to meet the current needs. Objectives: Gaps in application and problem-solving competencies of newly graduated laboratory personnel were discovered in Ethiopia, Tanzania and Kenya. New medical laboratory teaching content was developed in Ethiopia, Tanzania and Kenya using national instructors, tutors, and experts and consulting medical laboratory educators from the United States of America (USA. Method: Workshops were held in Ethiopia to create standardised biomedical laboratory science (BMLS lessons based on recently-revised course objectives with an emphasis on application of skills. In Tanzania, course-module teaching guides with objectives were developed based on established competency outcomes and tasks. In Kenya, example interactive presentations and lesson plans were developed by the USA medical laboratory educators prior to the workshop to serve as resources and templates for the development of lessons within the country itself. Results: The new teaching materials were implemented and faculty, students and other stakeholders reported successful outcomes. Conclusions: These approaches to updating curricula may be helpful as biomedical laboratory schools in other countries address gaps in the competencies of entry-level graduates.

Pacific Northwest National Laboratory created a network focused on collaboration in STEM education to design and deliver projects, resources, and professional learning opportunities in a testbed environment. How do you uncover and fill gaps in equitable access to high-quality science, technology, engineering, and math (STEM) education offerings in your local region? Where might you deploy strategies to improve STEM workforce preparation and increase public understanding of STEM-oriented issues? And how can you help to ensure that students, educators, parents, and the community are aware of these programs and know how to access them in schools, colleges, and community venues? If you are the Pacific Northwest National Laboratory (PNNL), you take on the huge goal of designing and implementing an innovative STEM education collaboration project that impacts all levels of local education, both inside and outside of school settings. PNNL is one of the 17 national laboratories funded by the U.S. Department of Energy. Operated by Battelle, PNNL has a vested interest in preparing the next generation of scientists and engineers for their future careers, thus building a STEM-capable workforce and creating a STEM-literate community. One of Battelle’s core principles is a commitment to STEM education and its role in business competitiveness and quality of life. PNNL has been active in STEM education for decades, providing internships for future scientists, giving educators in-house lab experiences, and engaging its researchers in STEM outreach activities in classrooms and the community. The Collaboratory is a relatively recent outcome of Battelle’s longstanding efforts in STEM education. The original Collaboratory planning documents, developed by PNNL’s Office of STEM Education (OSE), state the objective to “design, implement, and mature a local STEM education collaboration zone that highlights the power of PNNL and Battelle to impact the educational ecosystem and serve

Theoretical knowledge in biology and medicine plays a substantial role in laboratory medicine resident education. In this study, we assessed the contribution of problem-based learning (PBL) to improve the training of laboratory medicine residents during their internship in the department of virology, Strasbourg University Hospital, France. We compared the residents' satisfaction regarding an educational program based on PBL and a program based on lectures and presentations. PBL induced a high level of satisfaction (100%) among residents compared to lectures and presentations (53%). The main advantages of this technique were to create a situational interest regarding virological problems, to boost the residents' motivation and to help them identify the most relevant learning objectives in virology. However, it appears pertinent to educate the residents in appropriate bibliographic research techniques prior to PBL use and to monitor their learning by regular formative assessment sessions.

Hayes, Dana; Turczynski, Craig; Rice, Jonny; Kozhevnikov, Michael

2014-07-01

Researchers and educators have observed great potential in virtual reality (VR) technology as an educational tool due to its ability to engage and spark interest in students, thus providing them with a deeper form of knowledge about a subject. The focus of this project is to develop an interactive VR educational module, Laser Diode Characteristics and Coupling to Fibers, to integrate into a fiber optics laboratory course. The developed module features a virtual laboratory populated with realistic models of optical devices in which students can set up and perform an optical experiment dealing with laser diode characteristics and fiber coupling. The module contains three increasingly complex levels for students to navigate through, with a short built-in quiz after each level to measure the student's understanding of the subject. Seventeen undergraduate students learned fiber coupling concepts using the designed computer simulation in a non-immersive desktop virtual environment (VE) condition. The analysis of students' responses on the updated pre- and post tests show statistically significant improvement of the scores for the post-test as compared to the pre-test. In addition, the students' survey responses suggest that they found the module very useful and engaging. The conducted study clearly demonstrated the feasibility of the proposed instructional technology for engineering education, where both the model of instruction and the enabling technology are equally important, in providing a better learning environment to improve students' conceptual understanding as compared to other instructional approaches.

The Southwest Partnership on Carbon Sequestration completed its Phase I program in December 2005. The main objective of the Southwest Partnership Phase I project was to evaluate and demonstrate the means for achieving an 18% reduction in carbon intensity by 2012. Many other goals were accomplished on the way to this objective, including (1) analysis of CO{sub 2} storage options in the region, including characterization of storage capacities and transportation options, (2) analysis and summary of CO{sub 2} sources, (3) analysis and summary of CO{sub 2} separation and capture technologies employed in the region, (4) evaluation and ranking of the most appropriate sequestration technologies for capture and storage of CO{sub 2} in the Southwest Region, (5) dissemination of existing regulatory/permitting requirements, and (6) assessing and initiating public knowledge and acceptance of possible sequestration approaches. Results of the Southwest Partnership's Phase I evaluation suggested that the most convenient and practical ''first opportunities'' for sequestration would lie along existing CO{sub 2} pipelines in the region. Action plans for six Phase II validation tests in the region were developed, with a portfolio that includes four geologic pilot tests distributed among Utah, New Mexico, and Texas. The Partnership will also conduct a regional terrestrial sequestration pilot program focusing on improved terrestrial MMV methods and reporting approaches specific for the Southwest region. The sixth and final validation test consists of a local-scale terrestrial pilot involving restoration of riparian lands for sequestration purposes. The validation test will use desalinated waters produced from one of the geologic pilot tests. The Southwest Regional Partnership comprises a large, diverse group of expert organizations and individuals specializing in carbon sequestration science and engineering, as well as public policy and outreach.

2008-01-01

Southwest Airlines continues to garner accolades in the areas of customer service, workforce management, and profitability. Since both the health care and airlines industries deal with a service rather than a product, the customer experience depends on the people who deliver that experience. Employees' commitment or "loyalty" to their customers, their employer, and their work translates into millions of dollars of revenue. What employee wants to work for "the worst employer in town?" Nine loyalty lessons from Southwest can be carried over to the health care setting for the benefit of employees and patients.

Larour, E. Y.; Halkides, D. J.; Romero, V.; Cheng, D. L.; Perez, G.

2014-12-01

In the past decade, great strides have been made in the development of models capable of projecting the future evolution of glaciers and the polar ice sheets in a changing climate. These models are now capable of replicating some of the trends apparent in satellite observations. However, because this field is just now maturing, very few efforts have been dedicated to adapting these capabilities to education. Technologies that have been used in outreach efforts in Atmospheric and Oceanic sciences still have not been extended to Cryospheric Science. We present a cutting-edge, technologically driven virtual laboratory, geared towards outreach and k-12 education, dedicated to the polar ice sheets on Antarctica and Greenland, and their role as major contributors to sea level rise in coming decades. VISL (Virtual Ice Sheet Laboratory) relies on state-of-the art Web GL rendering of polar ice sheets, Android/iPhone and web portability using Javascript, as well as C++ simulations (back-end) based on the Ice Sheet System Model, the NASA model for simulating the evolution of polar ice sheets. Using VISL, educators and students can have an immersive experience into the world of polar ice sheets, while at the same exercising the capabilities of a state-of-the-art climate model, all of it embedded into an education experience that follows the new STEM standards for education.This work was performed at the California Institute of Technology's Jet Propulsion Laboratory under a contract with the National Aeronautics and Space Administration's Cryosphere Science Program.

Malhotra, Saurabh; Sobieraj, Diana M; Mann, April; Parker, Matthew W

2017-12-22

Background/Objectives: The specific credentials and continuing education (CME/CE) of nuclear cardiology laboratory medical and technical staff are important factors in the delivery of quality imaging services that have not been systematically evaluated. Methods: Nuclear cardiology accreditation application data from the Intersocietal Accreditation Commission (IAC) was used to characterize facilities performing myocardial perfusion imaging by setting, size, previous accreditation and credentials of the medical and technical staff. Credentials and CME/CE were compared against initial accreditation decisions (grant or delay) using multivariable logistic regression. Results: Complete data were available for 1913 nuclear cardiology laboratories from 2011-2014. Laboratories with initial positive accreditation decisions had a greater prevalence of Certification Board in Nuclear Cardiology (CBNC) certified medical directors and specialty credentialed technical directors. Certification and credentials of the medical and technical directors, respectively, staff CME/CE compliance, and assistance of a consultant with the application were positively associated with accreditation decisions. Conclusion: Nuclear cardiology laboratories directed by CBNC-certified physicians and NCT- or PET-credentialed technologists were less likely to receive delay decisions for MPI. CME/CE compliance of both the medical and technical directors was associated with accreditation decision. Medical and technical directors' years of experience were not associated with accreditation decision. Copyright © 2017 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Concentrating solar power (CSP) systems utilize the sun's energy to create heat that is used to generate electrical power. CSP systems in the United States are installed primarily in the Southwest, with 92% of plants that are operational, under construction, or under development located in three western states--Arizona, California, and Nevada. This report provides an overview of CSP development in these states, or the 'Southwest' for the purposes of this discussion, with a particular focus on the water supply issues associated with CSP. The Western Governors' Association (WGA) commissioned staff from the Western States Water Council (WSWC) to collaborate with staff from the National Renewable Energy Laboratory (NREL) to prepare this report. The WGA has long supported the effective management of the West's water resources, as well as the development of a clean, diverse, reliable, and affordable energy supply consisting of traditional and renewable energy resources. This report is specifically intended to help inform these goals, especially as WGA continues to underwrite a Regional Transmission Expansion Planning project, undertaken by the WSWC and the Western Electricity Coordinating Council (WECC), to better understand energy development within the existing and future water resource constraints of the West. This report builds upon earlier research conducted by NREL, the University of Colorado-Boulder, and Stanford University that was supported through the Joint Institute for Strategic Energy Analysis (JISEA) and presents information gathered through extensive research and literature reviews, as well as interviews and outreach with state water administrators and energy regulators, WECC and other experts familiar with CSP development in the Southwest.

Full Text Available This work aims to implement and evaluate an interactive educational software that helps Civil Engineering students to perform and analyze the calculations related to different Soil Mechanics laboratory tests. This experience consists of an attempt to incorporate information and communication technologies (ICTs into the engineering teaching-learning process. The content of the program is distributed into three different modules: “Compaction test”, “Consolidation test”, and “Direct shear test”. Using vector graphics, tables, illustrative figures, animations, equations, tip buttons, and immediate correction of mistakes, the software clarifies the relationship between theoretical concepts and practical laboratory results, instructs the students in the moments of doubt, attracts their interest, and motivates them to achieve the complete data interpretation. Based on the results of an applied evaluation questionnaire, it was observed that most of the students were satisfied with the contents and functionalities of the program. The developed tool can be an inspiration for the creation of new educational software that improve the quality of education in different engineering areas.

Educational and laboratory base for the expert training on physical protection of nuclear materials: the requirements and experience of practical implementation

2002-01-01

Full text: In expert training on physical protection of nuclear materials (NMPP) an educational and laboratory base has special importance. In these laboratories the students receive practical skills concerning physical protection systems (PPS). The basic requirements for creating such base are formulated in a certain educational program implemented at an educational institution. Thus it is necessary to take into account the following features of a modern nuclear object PPS: restriction of an object visiting with the purpose of acquaintance with features of a certain object PPS; dynamical change of PPS component nomenclature; increase of use of computer facilities for managing all PPS subsystems; increase of integration degree of separate subsystems in a uniform PPS complex; high cost of PPS components. Taking that into consideration a university, which assumes to begin the expert training on NMPP, is compelled to solve the following tasks: creation of its own laboratory base. The implementation of practical occupations with visiting a nuclear object cannot be executed practically; definition of quantity and structure of educational laboratories. Thus the features of the implemented educational plan should be taken into account in addition; optimization of expenses on laboratory creation. The regular updating of laboratory equipment structure is impossible in a practical manner. Therefore unique correct decision is to supply laboratories with the equipment, which uses the typical technological decisions on performing the basic PPS functions (detection, delay, estimation of a situation, neutralization); development of laboratory work conducting procedures (laboratory practical works); technical support of the created laboratories. The certain experience of solving the listed tasks is accumulated at the Moscow Engineering Physics Institute (State University) (MEPhl) while implementing 'Physical Protection, Control and Accountability of Nuclear Materials' master

To estimate the velocity of HCV subtype 6a transmission in Southwest China. The HCV CE1 region from 61 patients infected with HCV genotype 6 were amplificated by RT-PCR and sequenced. The subtypes were identified, and the period of HCV 6a strains originated in southwest china was estimated by using molecular clock phylogenetic analysis. The velocity of HCV subtype 6a transmission in southwest China was estimated by BEAST v1.6.1 and Tracer v1.5 software theoretically. Most of HCV 6a strains distributed in Southwest China origine around the year 1968 and at last 4 epidemic strains existed. The earlier origine strains could be isolated both in intravenous drug users (IDU) and non-IDU patients. After 1997, the HCV 6a strains transmission in southwest China accelerated and the trend intensified in 2007. HCV 6a strains spread fastly both in IDU and non-IDU patients, which might be the main HCV subtype distributed in Southwest China in the future.

This study evaluated the impact of nutritional education on knowledge, attitude and practices (KAP) of mothers concerning infants and young children feeding and their children's nutritional status in two semi-urban communities of south-west Nigeria. This is a community intervention study. We recruited 150 mothers of children aged 0-18 months independently from the intervention and control communities through a multi-stage sampling technique. We collected data with the aid of an interviewer-administered questionnaire at baseline and at six months after intervention from both communities to obtain information on feeding of infants and young children. In addition, we measured weights and heights of recruited children. Intervention involved group counselling of mothers and food demonstrations at designated health facilities. Data analysis for quantitative data was done using Epi-Info software, and for qualitative data, content analysis of major themes was used. Before intervention, recruited mothers and their children from the two communities were comparable in terms of all the parameters assessed (P>0.05 in all cases). After six months of intervention, mothers who had nutritional education demonstrated better knowledge and attitudes to key infant and young children feeding recommendations. There was also limited improvement in feeding practices. Mothers from the intervention community exclusively breastfed their infants longer with mean age at introduction of complementary foods at 5.3 months compared to 4.5 months in the control community (Pchildren longer (Pchildren. In this study, nutritional education of mothers only had positive impact on their level of KAP on infant and young children feeding.

Amolins, Michael W.; Ezrailson, Cathy M.; Pearce, David A.; Elliott, Amy J.

2015-01-01

The process of developing effective science educators has been a long-standing objective of the broader education community. Numerous studies have recommended not only depth in a teacher's subject area but also a breadth of professional development grounded in constructivist principles, allowing for successful student-centered and inquiry-based instruction. Few programs, however, have addressed the integration of the scientific research laboratory into the science classroom as a viable approach to professional development. Additionally, while occasional laboratory training programs have emerged in recent years, many lack a component for translating acquired skills into reformed classroom instruction. Given the rapid development and demand for knowledgeable employees and an informed population from the biotech and medical industries in recent years, it would appear to be particularly advantageous for the physiology and broader science education communities to consider this issue. The goal of this study was to examine the effectiveness of a laboratory-based professional development program focused on the integration of reformed teaching principles into the classrooms of secondary teachers. This was measured through the program's ability to instill in its participants elevated academic success while gaining fulfillment in the classroom. The findings demonstrated a significant improvement in the use of student-centered instruction and other reformed methods by program participants as well as improved self-efficacy, confidence, and job satisfaction. Also revealed was a reluctance to refashion established classroom protocols. The combination of these outcomes allowed for construction of an experiential framework for professional development in applied science education that supports an atmosphere of reformed teaching in the classroom.

Lejeune, K; Galbraith, H; Lipton, J; Kapustka, L A

1996-10-01

: Concentrations of metals and arsenic in floodplain soils of Silver Bow Creek and the upper Clark Fork River in southwest Montana were related to phytotoxic responses by individual plants in laboratory experiments, vegetative community structure and composition in the field and wildlife habitat. Samples collected from barren or very sparsely vegetated mixed mine tailings and alluvium deposits (slickens) in the floodplains along Silver Bow Creek and the Clark Fork River had concentrations of As, Cd, Cu, Pb and Zn that were significantly elevated relative to reference sites. Laboratory phytotoxicity tests demonstrated severe and rapid effects of the elevated concentrations of metals and As on hybrid poplar and standard test species (alfalfa, lettuce and wheat): growth inhibition of hybrid poplars was nearly 100% and of standard test species ≥75%. Vegetation community measurements revealed that slickens have replaced riparian forest, shrub, hay fields and pasture land; in doing so, the slickens have reduced both the compositional and structural heterogeneity of the riparian habitat. This reduction in habitat complexity has reduced the capacity of the area to provide a diversity of suitable wildlife habitat.

2012-01-01

Southwest China is one of the important areas where uranium is distributed. After exploration and research of 50 years, the metallogenic conditions for uranium deposits in Southwest China have been studied more deeply. It is found that uranium ore in Southwest China has more complete types, less deposits and more mineral occurrences, and the amount of uranium resources is disproportionate to the area of Southwest China. Researches of years show that Southwest China is characterized by thick crust. thick sedimentary cover, weak crust-mantle interaction, weak deep flu id activity in shallow strata, strong dynamic formation in shallow strata and obvious deep geologic process on block mar- gins. In this paper, the control of deep geologic process and evolution in uranium metallogenesis in Southwest China is studied by employing new theories and thoughts on the fundamental concept that deep geologic process and evolution has important control on super-large scale deposits. The study focuses on the crust-mantle structure and evolution with uranium metallogenesis, structural and magmatic activity and deep fluid activity with uranium metallogenesis, and ore-con- trolling role of penetrating faults on block edges and inside the blocks. To offer theoretic basis for large-scale uranium deposit prospecting in Southwest China, the key research on uranium deposit in Southwest China in future should be on the deep geologic evolution and uranium metallogenesis in Western Qinling Region, the uranium metallogenesis of iron oxide copper gold deposits on Kangdian axis, the uranium metallogenesis in Yunnan-Guizhou contiguous area, the hydrothermal uranium metallogenesis in Eastern Tibet and Western Sichuan, and the connection between sandstone type uranium deposit and magmatic activity. Meanwhile, the above regions are also the key ones for uranium deposit prospecting in Southwest China in a rather long period in future. (authors)

Interdisciplinary STEM education reform: dishing out art in a microbiology laboratory.

Science.gov (United States)

Adkins, Sarah J; Rock, Rachel K; Morris, J Jeffrey

2018-01-01

In the modern educational framework, life science and visual art are usually presented as mutually exclusive subjects. Despite this perceived disciplinary contrast, visual art has the ability to engage and provoke students in ways that can have important downstream effects on scientific discovery, especially when applied in a practical setting such as a laboratory course. This review broadly examines the benefit of interdisciplinary fusions of science and art as well as recent ways in which art strategies have been used in undergraduate biology classrooms. In a case study, we found that undergraduate students in an introductory microbiology laboratory course who participated in open-inquiry activities involving agar art had greater confidence in their personal efficacy as scientists compared to a control class. Collectively, these observations suggest that visual art can be a useful enhancement in the course-based undergraduate research setting, and science educators at all levels should consider incorporating artistic creativity in their own classroom strategies. © FEMS 2017.

The process of developing effective science educators has been a long-standing objective of the broader education community. Numerous studies have recommended not only depth in a teacher's subject area but also a breadth of professional development grounded in constructivist principles, allowing for successful student-centered and inquiry-based instruction. Few programs, however, have addressed the integration of the scientific research laboratory into the science classroom as a viable approach to professional development. Additionally, while occasional laboratory training programs have emerged in recent years, many lack a component for translating acquired skills into reformed classroom instruction. Given the rapid development and demand for knowledgeable employees and an informed population from the biotech and medical industries in recent years, it would appear to be particularly advantageous for the physiology and broader science education communities to consider this issue. The goal of this study was to examine the effectiveness of a laboratory-based professional development program focused on the integration of reformed teaching principles into the classrooms of secondary teachers. This was measured through the program's ability to instill in its participants elevated academic success while gaining fulfillment in the classroom. The findings demonstrated a significant improvement in the use of student-centered instruction and other reformed methods by program participants as well as improved self-efficacy, confidence, and job satisfaction. Also revealed was a reluctance to refashion established classroom protocols. The combination of these outcomes allowed for construction of an experiential framework for professional development in applied science education that supports an atmosphere of reformed teaching in the classroom.

2013-01-01

Full Text Available Computer network used for laboratory training and for different types of network and security experiments represents a special environment where hazardous activities take place, which may not affect any production system or network. It is common that students need to have administrator privileges in this case which makes the overall security and maintenance of such a network a difficult task. We present our solution which has proved its usability for more than three years. First of all, four user requirements on the laboratory network are defined (access to educational network devices, to laboratory services, to the Internet, and administrator privileges of the end hosts, and four essential security rules are stipulated (enforceable end host security, controlled network access, level of network access according to the user privilege level, and rules for hazardous experiments, which protect the rest of the laboratory infrastructure as well as the outer university network and the Internet. The main part of the paper is dedicated to a design and implementation of these usability and security rules. We present a physical diagram of a typical laboratory network based on multiple circuits connecting end hosts to different networks, and a layout of rack devices. After that, a topological diagram of the network is described which is based on different VLANs and port-based access control using the IEEE 802.1x/EAP-TLS/RADIUS authentication to achieve defined level of network access. In the second part of the paper, the latest innovation of our network is presented that covers a transition to the system virtualization at the end host devices – inspiration came from a similar solution deployed at the Department of Telecommunications at Brno University of Technology. This improvement enables a greater flexibility in the end hosts maintenance and a simultaneous network access to the educational devices as well as to the Internet. In the end, a vision of a

Lab-scale models of geophysical phenomena have a long history in research and education. For example, at the University of Chicago, Dave Fultz developed laboratory-scale models of atmospheric flows. The results from his laboratory were so stimulating that similar laboratories were subsequently established at a number of other institutions. Today, the Dave Fultz Memorial Laboratory for Hydrodynamics (http://geosci.uchicago.edu/~nnn/LAB/) teaches general circulation of the atmosphere and oceans to hundreds of students each year. Following this tradition, we have constructed a lab model of iceberg-capsize dynamics for use in the Fultz Laboratory, which focuses on the interface between glaciology and physical oceanography. The experiment consists of a 2.5 meter long wave tank containing water and plastic "icebergs". The motion of the icebergs is tracked using digital video. Movies can be found at: http://geosci.uchicago.edu/research/glaciology_files/tsunamigenesis_research.shtml. We have had 3 successful undergraduate interns with backgrounds in mathematics, engineering, and geosciences perform experiments, analyze data, and interpret results. In addition to iceberg dynamics, the wave-tank has served as a teaching tool in undergraduate classes studying dam-breaking and tsunami run-up. Motivated by the relatively inexpensive cost of our apparatus (~1K-2K dollars) and positive experiences of undergraduate students, we hope to serve as a model for undergraduate research and education that other universities may follow.

Pre-analytic errors during diagnostic laboratory investigations can lead to increased patient morbidity and mortality. This study aimed to ascertain the effect of educational nursing activities on the incidence of pre-analytical errors resulting in non-conforming blood samples. This study was conducted between January 2008 and December 2015. All specimens received at the Haematology Laboratory of the Sultan Qaboos University Hospital, Muscat, Oman, during this period were prospectively collected and analysed. Similar data from 2007 were collected retrospectively and used as a baseline for comparison. Non-conforming samples were defined as either clotted samples, haemolysed samples, use of the wrong anticoagulant, insufficient quantities of blood collected, incorrect/lack of labelling on a sample or lack of delivery of a sample in spite of a sample request. From 2008 onwards, multiple educational training activities directed at the hospital nursing staff and nursing students primarily responsible for blood collection were implemented on a regular basis. After initiating corrective measures in 2008, a progressive reduction in the percentage of non-conforming samples was observed from 2009 onwards. Despite a 127.84% increase in the total number of specimens received, there was a significant reduction in non-conforming samples from 0.29% in 2007 to 0.07% in 2015, resulting in an improvement of 75.86% ( P educational activities directed primarily towards hospital nursing staff had a positive impact on the quality of laboratory specimens by significantly reducing pre-analytical errors.

The Role of the National Laboratory in Improving Secondary Science Education

2008-10-20

While the role of science, technology, engineering, and mathematics (STEM) teachers in our education system is obvious, their role in our economic and national security system is less so. Our nation relies upon innovation and creativity applied in a way that generates new technologies for industry, health care, and the protection of our national assets and citizens. Often, it is our science teachers who generate the excitement that leads students to pursue science careers. While academia provides these teachers with the tools to educate, the rigors of a science and technology curriculum, coupled with the requisite teaching courses, often limit teacher exposure to an authentic research environment. As the single largest funding agency for the physical sciences, the US Department of Energy's (DOE) Office of Science plays an important role in filling this void. For STEM teachers, the DOE Academies Creating Teacher Scientists program (ACTS) bridges the worlds of research and education. The ACTS program at Brookhaven National Laboratory (BNL), one of several across the country, exemplifies the value of this program for participating teachers. Outcomes of the work at BNL as evidenced by the balance of this report, include the following: (1) Teachers have developed long-term relationships with the Laboratory through participation in ongoing research, and this experience has both built enthusiasm for and enriched the content knowledge of the participants. (2) Teachers have modified the way they teach and are more likely to engage students in authentic research and include more inquiry-based activities. (3) Teachers have reported their students are more interested in becoming involved in science through classes, extra-curricular clubs, and community involvement. (4) Teachers have established leadership roles within their peer groups, both in their own districts and in the broader teaching community. National laboratories are making an important contribution to the

Full Text Available Introduction. The morbidity and mortality from malaria are still unacceptably high in the developing countries, especially among the vulnerable groups like pregnant women and under-five children, despite all control efforts. The knowledge about the preventive measures of malaria is an important preceding factor for the acceptance and use of malaria preventive measures like Insecticide Treated Nets (ITN by community members. Therefore, this study assessed the knowledge of malaria prevention among caregivers of under-five children and pregnant women in a rural community in Southwest Nigeria.Methodology. This is part of a larger malaria prevention study in rural Southwest Nigeria. A descriptive cross-sectional survey was conducted among pregnant women and caregivers of under-five children in Igbo-Ora, a rural town in Southwest Nigeria using a semi-structured, interviewer-administered questionnaire. Information was obtained on knowledge of malaria prevention, and overall composite scores were computed for knowledge of malaria prevention and ITN use. Data were analyzed using SPSS version 16. Associations between variables were tested using a Chi-square with the level of statistical significance set at 5%.Results. Of the 631 respondents, 84.9% were caregivers of under-five children and 67.7% were married. Mean age was 27.7 ± 6.3 years with 53.4% aged between 20 and 29 years. Majority (91.1% had at least primary school education and 60.2% were traders. Overall, 57.7% had poor knowledge of malaria prevention. A good proportion (83.5% were aware of the use of ITN for malaria prevention while 30.6% had poor knowledge of its use. Respondents who were younger (<30 years, had at least primary education and earn <10,000/per month had significantly poor knowledge of ITN use in malaria prevention. Majority (60.0% respondents had poor attitude regarding use of ITNs.Conclusion. This study showed that the knowledge of malaria prevention is still low among under

Proficiency in medical nutrition requires an understanding of food-related biochemistry and the application of this knowledge in the context of culinary, cultural, psychosocial and interprofessional components. Our aim was to develop a teaching format where medical students could learn the biochemistry of nutrition in the context of patient narratives, interactive cooking and dialogues with nutrition professionals. We designed and implemented a day-long culinary laboratory intervention (lab), which is taught to first-year medical students at the University of Rochester with the help of dietetic interns from Cornell University. Here, we present the details of the intervention, the resources used and the preliminary outcomes on student attitudes. We designed and implemented a day-long culinary lab, which is taught to first-year medical students A questionnaire with quantitative rating scales and open-ended questions was used to probe student attitudes regarding the educational approach used in the lab. Our preliminary findings suggest that the lab was well received and that the dietetic interns were viewed as effective teachers in this context. A culinary lab is a feasible educational environment for integrating the breadth of topics within the discipline of nutrition. The experiential, food-based format appears to stimulate questions central to current nutritional controversies, particularly challenges related to translating biochemical mechanism into practical nutrition interventions. Close involvement with basic science faculty members, clinical faculty members and allied health professions are essential for this type of endeavour. © 2015 John Wiley & Sons Ltd.

Southwest Asia, which support 1/3 of the world's population, is acutely aware of the consequences of rapid and excessive population growth. No other region has consciously devoted so much of its resources to stemming excessive population growth. India, with a population of 684 million, formulated a policy of population limitation in the 1950s. The 1980 government rededicated itself to voluntary family planning and rebuilt the broad coalition of an excellent infrastructure of government institutions, voluntary organizations, and international agencies. Government support for family planning clinics began in Bangladesh in the 1960s. A strong institutional structure has been established under the supervision of the National Population Council. Innovative approaches to family planning service delivery have been initiated by an admirable array of institutions. Pakistan's Population Welfare Plan provides substantial funds and an administrative structure to make maternal/child helath care and family planning services available in rural areas. Another welfare program encourages smaller families through projects to enhance the status of women by improving literacy, establishing rural industries, and advocating late marriage. Nepal has had to struggle with a poor administrative structure, grossly insufficient medical services, and an inadequate database for policy formulation. Family planning services are now a component of the overall health program. The family planning services of the pioneer Afghan Family Guidance Association, established in 1968, have been incorported into the national maternal/child health program. The present government of Iran views foreign assistance as an unacceptable form of persuasion and has phased out all international funded family planning programs. Sri Lanka is the only country in the region to have made the demographic transition to fertility decline. An impressive health infrastructure delivers family planning services at every level using

2012-01-01

Uranium is widely distributed in South-west China, with all types but on a not-so-large scale. South-west China is located on the combining site of several large tectonic elements and every tectonic movement has different effects on different regions. To study and clarify the correlation between the major geological events in South-west China and the Uranium metallogenesis, comprehensive research and field investigation are made besides collecting a lot of materials. Through analysis and research on the major geological events in South-west China, the evolution of those e vents is basically clarified and the events closely related with uranium mineralization are determined. It is discovered that there are several ore-forming geologic events in the geological history of South-west China; almost every major tectonic movement cycle is accompanied with uranium metallogenesis, from Jinning Movement to Chengjiang Movement, to Hercynian Movement, to Indosinian Movement. to Yanshan Movement. to Himalayan movement. Even though every major tectonic cycle is accompanied with uranium mineralization, three major geological events are generally obviously related with uranium metallogenesis, i.e. the Rodinian supercontinent breakup even in Jinning-Chengjiang Period, Yanshan Movement and Himalayan movement, in which the first one is the process of uranium pre-enrichment and provides the source of uranium. Yanshan Movement and Himalayan movement are the important processes for mineralization, mainly the hydrothermal superimposed mineralization. (authors)

Evaluation of the status of laboratory practices and the need for continuing education in medical mycology.

Rosner, Eunice R; Reiss, Errol; Warren, Nancy G; Shadomy, H Jean; Lipman, Harvey B

2002-08-01

A survey to determine the need for training in medical mycology was sent to 605 US laboratories. Training needs were determined by comparing actual laboratory mycology practices with recommended practices, documenting the extent of mycology training reported by employees, and asking respondents to specify the fungi they considered most difficult to identify. The response rate was 56.7% (with only 316 laboratories providing sufficient information). Results showed a large degree of interlaboratory variation in practices and suggested that more judicious practices could lower costs and improve clinical relevance. Only 55.6% of laboratories reported that at least 1 employee attended a formal mycology continuing education program in the 4 years before the survey. Species of dermatophytes, dematiaceous fungi, and non-Candida yeasts were the most difficult to identify. Training may be needed in basic isolation procedures and in advanced topics such as identification of problematic molds and yeasts and antifungal susceptibility testing. Educators should consider clinical relevance and cost-containment without sacrificing quality when designing courses. Support for additional mycology training may improve if hospital and laboratory administrators are alerted to potential dangers and costs involved in treating patients with invasive fungal infections.

Full Text Available This work examined politics-administration interface and the sustenance of public service ethos in Southwest Nigeria. Public servants and political functionaries in Southwest Nigeria are constantly in a struggle to fix each other in their pre-conceived mould of mental judgment which invariably breeds mutual suspicion, apprehension and setting the stage for conflict which is likely to impact negatively on the performance of public servants in Southwest Nigeria. The article identified the factors influencing the interface of public servants and political office holders in Southwest Nigeria. It also determined the influence of the interface between on public service ethos and finally examined the efforts made towards sustaining public service ethos in Southwest Nigeria. In carrying out this work, primary and secondary data were used. In the case of primary data, survey was carried out and questionnaire was used to elicit information from respondents in the Southwest geo-political zone of the country. Purposive random sampling techniques were adopted to determine the target respondents. The study has a sample of five hundred and thirty-five (535, which constitute 50 percent of the total population figure of 1070.  The findings revealed amongst others, that the synergy between political functionaries and public office holders is often characterized by both conflict and cooperation. In addition, there are certain factors influencing the interface of public servants and political office holders in Southwest Nigeria, these factors include: contract awards, consideration in the appointment of top civil servants etc. The study therefore, recommends the need for Southwest Nigeria to strengthen politics-administration interface in such a way that the public services in that region will be more productive. There is also the need for government in the Southwest to clarify the respective roles of political office holders and public servants. The principles

This study aimed to assess the prevalence and risk behaviors for HBV infection among high risk groups in Kohgiloyeh and Boyerahmad province, in Southwest of Iran. Methods Blood samples were collected from 2009 subjects, between 2009 and 2010 in Kohgiloyeh and Boyerahmad province, in southwest of Iran. Recruited subjects were the high risk groups for HBV infection, including inmates, injecting drug users, health care workers, patients on maintenance haemodialysis, hemophilic patients and patients with a history of blood transfusion. Their serum samples were tested for the presence of antibodies to hepatitis B core antigen (HBc IgM, IgG by enzyme-linked immunosorbent assay (ELISA. Seropositive specimens were tested for HBsAg. Demographic features of participants were recorded during sample collecting. Results HBsAg was detected in 24 of the 2009 subjects, giving an overall prevalence of 1.2%. All HBsAg positive cases were males. The prevalence of HBsAg among injection drug users was 3.2%. Significant correlation was found between HBV infection and drug abuse, level of education and place of residence (p Conclusion Based on the findings of this study, incarceration and drug abuse are the most important risk factors for acquiring HBV infection in this region. Modifying behavior, improving the individual education and expanding the HBV vaccination coverage may reduce the rate of infection in the region.

[Water and environment in the Southwest of Madagascar].

Science.gov (United States)

Razanamparany, L

1993-04-01

The dry and arid southwest region of Madagascar is not a desert but resembles the Sahel region of West Africa. The chronic water deficit is aggravated by the heat and constant winds that accelerate evapotranspiration on the permeable soils. The dryness occurs because the southwest region lies outside the main pluviogenic systems. Erosion occurs at all seasons. In the winter the sun and winds are the main causes, while the rare storms are more conducive to run-off and to erosion than to absorption. The acute water shortage in the southwest has prompted hydrogeologic research and well-drilling, but the high salt content of the water and other impurities will be a limiting factor for development of the area. The population of the southwest is extremely mobile. Human settlements are concentrated in the valleys and depressions and along major roads. Customary rights to land under the control of the traditional chiefs regulate tenure in most areas. But especially in the river bottoms, the coming of cash crops cultivated with modern equipment has resulted in significant erosion which has aggravated ecological problems. Accelerating soil degradation has led peasants to extend their lands under cultivation to the detriment of forest cover. Cattle herding remains the principal economic activity in the southwest. Herding has progressed from nomadism to pastoralism, but it remains a sign of power and wealth. Transhumance is the strategy of herders faced with shortages of water and pasturage, demographic pressure, and environmental degradation. Raising of sheep and goats constitutes a supplemental food source, medium of exchange, and form of savings. But angora goats graze on everything in their path, devastating their surrounds. Fear of cattle thefts militates against efforts to improve the quality of the stock. The various problems together have prompted a wasteful exploitation of the forest resources. Development strategies for the area explored by the government have all

A Typology for Charting Socioeconomic Mortality Gradients: "Go Southwest".

Blakely, Tony; Disney, George; Atkinson, June; Teng, Andrea; Mackenbach, Johan P

2017-07-01

Holistic depiction of time-trends in average mortality rates, and absolute and relative inequalities, is challenging. We outline a typology for situations with falling average mortality rates (m↓; e.g., cardiovascular disease), rates stable over time (m-; e.g., some cancers), and increasing average mortality rates (m↑; e.g., suicide in some contexts). If we consider inequality trends on both the absolute (a) and relative (r) scales, there are 13 possible combination of m, a, and r trends over time. They can be mapped to graphs with relative inequality (log relative index of inequality [RII]; r) on the y axis, log average mortality rate on the x axis (m), and absolute inequality (slope index of inequality; SII; a) as contour lines. We illustrate this by plotting adult mortality trends: (1) by household income from 1981 to 2011 for New Zealand, and (2) by education for European countries. Types range from the "best" m↓a↓r↓ (average, absolute, and relative inequalities all decreasing; southwest movement in graphs) to the "worst" m↑a↑r↑ (northeast). Mortality typologies in New Zealand (all-cause, cardiovascular disease, nonlung cancer, and unintentional injury) were all m↓r↑ (northwest), but variable with respect to absolute inequality. Most European typologies were m↓r↑ types (northwest; e.g., Finland), but with notable exceptions of m-a↑r↑ (north; e.g., Hungary) and "best" or southwest m↓a↓r↓ for Spain (Barcelona) females. Our typology and corresponding graphs provide a convenient way to summarize and understand past trends in inequalities in mortality, and hold potential for projecting future trends and target setting.

Full Text Available Many undergraduate laboratories are, too often, little more than an exercise in “cooking” where students are instructed step-by-step what to add, mix, and, most unfortunately, expect as an outcome. Although the shortcomings of “cookbook” laboratories are well known, they are considerably easier to manage than the more desirable inquiry-based laboratories. Thus the ability to quickly access, share, sort, and analyze research data would make a significant contribution towards the feasibility of teaching/mentoring large numbers of inexperienced students in an inquiry-based research environment, as well as facilitating research collaborations among students. Herein we report on a software tool (MicroTracker designed to address the educational problems that we experienced with inquiry-based research education due to constraints on data management and accessibility.

During the 1994 summer institute NTEP teachers worked in coordination with LANL and the Los Alamos Middle School and Mountain Elementary School to gain experience in communicating on-line, to gain further information from the Internet and in using electronic Bulletin Board Systems (BBSs) to exchange ideas with other teachers. To build on their telecommunications skills, NTEP teachers participated in the International Telecommunications In Education Conference (Tel*ED `94) at the Albuquerque Convention Center on November 11 & 12, 1994. They attended the multimedia keynote address, various workshops highlighting many aspects of educational telecommunications skills, and the Telecomm Rodeo sponsored by Los Alamos National Laboratory. The Rodeo featured many presentations by Laboratory personnel and educational institutions on ways in which telecommunications technologies can be use din the classroom. Many were of the `hands-on` type, so that teachers were able to try out methods and equipment and evaluate their usefulness in their own schools and classrooms. Some of the presentations featured were the Geonet educational BBS system, the Supercomputing Challenge, and the Sunrise Project, all sponsored by LANL; the `CU-seeMe` live video software, various simulation software packages, networking help, and many other interesting and useful exhibits.

Nontuberculous mycobacteria: incidence in Southwest Ireland from 1987 to 2000.

LENUS (Irish Health Repository)

Kennedy, M P

2012-02-03

SETTING: The Southwest of Ireland (Counties Cork and Kerry) 1987-2000, average population 549,500. OBJECTIVE: Nontuberculous mycobacteria (NTM) cause significant morbidity worldwide and the study of epidemiology and characteristics helps in their prevention and treatment. This study was performed to determine the incidence of NTM disease in comparison to Mycobacterium tuberculosis (M. tuberculosis) and Mycobacterium bovis (M. bovis) in Southwest Ireland, over the above time period. DESIGN: A retrospective study was carried out in all human isolates of NTM, M. tuberculosis and M. bovis between 1987 and 2000, in the Southwest Region of Ireland. RESULTS: The mean incidence of NTM (0.4\\/100,000 population) has risen since 1995, principally of pulmonary Mycobacterium avium intracellulare complex (MAC). The annual incidence of M. tuberculosis in humans over 14 years in the same region was 971\\/100,000 population with a significant reduction since 1994 and M. bovis remained constant at 0.5\\/100,000 population. CONCLUSION: The increasing incidence of disease causing NTM noted in Southwest Ireland reflects global data and is surmised to be due to an ageing population, increased incidence related to chronic fibrotic lung disease, and environmental mycobacterial factors.

Laboratory experiences are essential for optics education. However, college students have limited access to advanced optical equipment that is generally expensive and complicated. Hence there is a need for innovative solutions to expose students to advanced optics laboratories. Here we describe a novel approach, interactive virtual optical laboratory (IVOL) that allows unlimited number of students to participate the lab session remotely through internet, to improve laboratory education in photonics. Although students are not physically conducting the experiment, IVOL is designed to engage students, by actively involving students in the decision making process throughout the experiment.

[Future roles of clinical laboratories and clinical laboratory technologists in university hospitals].

Science.gov (United States)

Yokota, Hiromitsu; Yatomi, Yutaka

2013-08-01

Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.

Hoell, Andrew; Funk, Chris; Barlow, Mathew; Cannon, Forrest

2017-01-01

The socioeconomic difficulties of southwest Asia, defined as the area bound by the domain 25°N–40°N and 40°E–70°E, are exacerbated by extreme precipitation deficits during the November–April rainy season. The precipitation deficits during many southwest Asia droughts have been examined in terms of the forcing by climate variability originating over the Pacific Ocean as a result of the El Niño–Southern Oscillation (ENSO), Pacific decadal variability (PDV), and the long-term warming of Pacific (LT) sea surface temperatures (SST). Here we examine how the most extreme November–April southwest Asia droughts relate to global SSTs and the associated large-scale atmospheric circulation anomalies and analyze the specific atmospheric forcing mechanisms responsible for changes in regional southwest Asian precipitation. The driest November–April seasons during 1948–2012 over southwest Asia are forced by subsidence and reductions of moisture fluxes as a result of the interaction of the mean flow with anomalous zonally symmetric high pressure throughout the Northern Hemisphere. The anomalous zonally symmetric high pressure throughout the Northern Hemisphere occurs simultaneously with cool central and eastern Pacific SST anomalies associated with La Niña and the negative phase of PDV and a warm west Pacific Ocean caused in part by the long-term warming of the west Pacific Ocean.

Ground water is among the Nation’s most important natural resources. It provides drinking water to urban and rural communities, supports irrigation and industry, sustains the flow of streams and rivers, and maintains riparian and wetland ecosystems. In many areas of the Nation, the future sustainability of ground-water resources is at risk from overuse and contamination. Because ground-water systems typically respond slowly to human actions, a long-term perspective is needed to manage this valuable resource. This publication is one in a series of fact sheets that describe ground-water-resource issues across the United States, as well as some of the activities of the U.S. Geological Survey that provide information to help others develop, manage, and protect ground-water resources in a sustainable manner. Ground-water resources in the Southwest are among the most overused in the United States. Natural recharge to aquifers is low and pumping in many areas has resulted in lowering of water tables. The consequences of large-scale removal of water from storage are becoming increasingly evident. These consequences include land subsidence; loss of springs, streams, wetlands and associated habitat; and degradation of water quality. Water managers are now seeking better ways of managing ground-water resources while looking for supplemental sources of water. This fact sheet reviews basic information on ground water in the desert basins of the Southwest. Also described are some activities of the U.S. Geological Survey (USGS) that are providing scientific information for sustainable management of ground-water resources in the Southwest. Ground-water sustainability is defined as developing and using ground water in a way that can be maintained for an indefinite time without causing unacceptable environmental, economic, or social consequences.

The Grays Harbor Navigation Improvement Project was initiated to improve navigation by widening and deepening the federal channel at Grays Harbor. Dredged-material disposal sites were selected after an extensive review process that included inter-agency agreements, biological surveys, other laboratory and field studies, and preparation of environmental impact statements The Southwest Site, was designated to receive materials dredged during annual maintenance dredging as well as the initial construction phase of the project. The Southwest Site was located, and the disposal operations designed, primarily to avoid impacts to Dungeness crab. The Final Environmental Impact Statement Supplement for the project incorporated a Site Monitoring Plan in which a tiered approach to disposal site monitoring was recommended. Under Tier I of the Site Monitoring Plan, Dungeness crab densities are monitored to confirm that large aggregations of newly settled Dungeness crab have not moved onto the Southwest Site. Tier 2 entails an increased sampling effort to determine whether a change in disposal operations is needed. Four epibenthic surveys using beam trawls were conducted in 1990, 1991, and 1992 at the Southwest Site and North Reference area, where high crab concentrations were found in the spring of 1985. Survey results during these three years prompted no Tier 2 activities. Epibenthic surveys were also conducted at two nearshore sites where construction of sediment berms has been proposed. This work is summarized in an appendix to this report.

Drug problem in southeast and southwest Asia.

Science.gov (United States)

Kulsudjarit, Kongpetch

2004-10-01

In 2002, the drug problem in Southeast and Southwest Asia was serious, particularly in the production of opium and heroin in Afghanistan, Myanmar, and Laos, the three largest producers of illicit opium in the world. The increasing illicit manufacture of ATS, particularly methamphetamine, in Southeast Asia, mainly in China and Myanmar, was also a major concern. Some reports indicated that ephedrine, used for illicitly producing methamphetamine in Southeast Asia, is diverted and smuggled out of China and India, whereas caffeine, the adulterant used for producing methamphetamine tablets, is mainly smuggled into Myanmar through its border with Thailand. Seizure data showed a dramatic increase in trafficking in MDMA through Southeast Asia. In terms of the drug epidemic, in 2002, cannabis remained overall the main drug of abuse in all of the countries of Southeast and Southwest Asia. Opiates, mainly opium and heroin, were also the drugs of choice except in Thailand, where opiate abuse declined, but ATS was the main drug of abuse due to its low cost and availability. A significant increase in ATS abuse, amphetamine, methamphetamine, and MDMA among the youth who smoked, sniffed, and inhaled them was reported in Cambodia, China, Indonesia, Laos, Myanmar, the Philippines, and Thailand. Injecting drug use among opiate abusers has been identified as the prime cause of the rapid spread of HIV/AIDS in Southeast and Southwest Asia.

By means of five deep borings on the south-west side of the Asse anticline, the roof rock strata series in the vicinity of the mine building erected eastwestwards, and potentials aquiferous geologic horizons were investigated. A seismic cross profile gives a survey of the whole geologic structure of the Asse salt mine. Geologic and hydrogeologic explorations of the roof rock were carried out to analyse the characteristic formation and stratification of the rock strata adjacent to the Zechstein salt anticline in respect of their water-carrying and water-impounding features, as well as the saliniferous interstratification in the Keuper, Middle Shell-lime and Upper Bunter. Geomechanic and sediment-petrographic laboratory investigations on drill cores made it possible to determine the stiffness and jointing of the roof rock strata. Using borehole measurements, rock parameters measured in situ by geophysical methods were determined and the roof rock lithology described. (HP) [de

Evaluating the effectiveness of a laboratory-based professional development program for science educators

Science.gov (United States)

Amolins, Michael Wayne

The development of effective science educators has been a long-standing goal of the American education system. Numerous studies have suggested a breadth of professional development programs that have sought to utilize constructivist principles in order to orchestrate movement toward student-led, inquiry-based instruction. Very few, however, have addressed a missing link between the modern scientific laboratory and the traditional science classroom. While several laboratory-based training programs have begun to emerge in recent years, the skills necessary to translate this information into the classroom are rarely addressed. The result is that participants are often left without an outlet or the confidence to integrate these into their lessons. The purpose of this study was to examine the effectiveness of a laboratory-based professional development program focused on classroom integration and reformed science teaching principles. This was measured by the ability to invigorate its seven participants in order to achieve higher levels of success and fulfillment in the classroom. These participants all taught at public high schools in South Dakota, including both rural and urban locations, and taught a variety of courses. Participants were selected for this study through their participation in the Sanford Research/USD Science Educator Research Fellowship Program. Through the use of previously collected data acquired by Sanford Research, this study attempted to detail the convergence of three assessments in order to demonstrate the growth and development of its participants. First, pre- and post-program surveys were completed in order to display the personal and professional growth of its participants. Second, pre- and post-program classroom observations employing the Reformed Teaching Observation Protocol allowed for the assessment of pedagogical modifications being integrated by each participant, as well as the success of such modifications in constructively

Bush Physics for the 21st Century (BP21) is a distance education physics course offered through the Interior Aleutians Campus of the University of Alaska Fairbanks. It provides an opportunity for rural Alaskan high school and community college students, many of whom have no other access to advanced science courses, to earn university science credit. The curriculum is mathematically rigorous and includes a laboratory component to prepare students who wish to pursue science and technology careers. The laboratory component has been developed during the past 3 years. Students learn lab safety, basic laboratory technique, experiment components and group collaboration. Experiments have place-based themes and involve skills that translate to rural Alaska when possible. Preliminary data on the general effectiveness of the labs have been analyzed and used to improve the course.

The forcing of monthly precipitation variability over Southwest Asia during the Boreal cold season

Hoell, Andrew; Shukla, Shraddhanand; Barlow, Mathew; Cannon, Forest; Kelley, Colin; Funk, Christopher C.

2015-01-01

Southwest Asia, deemed as the region containing the countries of Afghanistan, Iran, Iraq and Pakistan, is water scarce and receives nearly 75% of its annual rainfall during8 the boreal cold season of November-April. The forcing of Southwest Asia precipitation has been previously examined for the entire boreal cold season from the perspective of climate variability originating over the Atlantic and tropical Indo-Pacific Oceans. Here, we examine the inter-monthly differences in precipitation variability over Southwest Asia and the atmospheric conditions directly responsible in forcing monthly November-April precipitation. Seasonally averaged November-April precipitation over Southwest Asia is significantly correlated with sea surface temperature (SST) patterns consistent with Pacific Decadal Variability (PDV), the El Nino-Southern Oscillation (ENSO) and the warming trend of SST (Trend). On the contrary, the precipitation variability during individual months of November-April are unrelated and are correlated with SST signatures that include PDV, ENSO and Trend in different combinations. Despite strong inter-monthly differences in precipitation variability during November- April over Southwest Asia, similar atmospheric circulations, highlighted by a stationary equivalent barotropic Rossby wave centered over Iraq, force the monthly spatial distributions of precipitation. Tropospheric waves on the eastern side of the equivalent barotropic Rossby wave modifies the flux of moisture and advects the mean temperature gradient, resulting in temperature advection that is balanced by vertical motions over Southwest Asia. The forcing of monthly Southwest Asia precipitation by equivalent barotropic Rossby waves is different than the forcing by baroclinic Rossby waves associated with tropically-forced-only modes of climate variability.

2012-01-01

[Objective]The research aimed to analyze temporal-spatial distribution characteristics of the precipitation anomaly in southwest China from 1951 to 2010. [Method] Based on monthly precipitation data at 44 stations of southwest China and 160 stations of China from 1951 to 2010, by using EOF analysis, wavelet analysis and composite analysis, monthly and seasonal change rules of the precipitation in southwest China were analyzed. Corresponding spatial-temporal distribution characteristics of the precipitation in drought and flood years were studied. Temporal-spatial distribution characteristics of the precipitation anomaly in southwest China in recent 60 years were revealed. [Result]Seasonal distribution of the precipitation in southwest China was uneven and was typical single-peak type. Precipitation concentrated from May to September, and peak appeared in July. In recent years, rainfall in autumn significantly became less, while that in other seasons had no obvious change. Precipitation in summer had the cycle of 14 years, another for 6 years and 3-4 years of periodic oscillations. In wet years, precipitation in southwest China had same phase with that in southern China, and anti-phase with that in the junction of Qinghai, Gansu, Xinjiang and Tibet. In dry years, precipitation in southwest China had same phase with that in the eastern part of northwest China and northern China. [Conclusion]The research provided reference basis for prediction and pre-warning of the precipitation in the zone.

Xue Zhou

2015-07-01

Full Text Available Objective: We examined whether dietary energy intake (EI and dietary energy density (ED were cross-sectionally associated with body composition of children living in Southwest China. Design and Methods: Multivariate regression analyses were performed on three day, 24 h dietary recall data and information on potential confounders from 1207 participants aged 8–14 years. EI was calculated from all foods and drinks and ED was classified into five categories. Body mass index (BMI z-scores, percentage of body fat (%BF, fat mass index (FMI, fat-free mass index (FFMI and ratio of waist to hip circumference (WHR were used to describe body composition. Results: Boys with higher total EI had higher BMI z-scores, %BF, and FMI than boys with lower total EI both before and after measurements were adjusted for confounders (age, fiber intake, physical activity, the timing of adding complementary foods, paternal education level and maternal BMI (p ≤ 0.04. However, EI was not associated with body composition in girls. Dietary ED, in any category, was not associated with body composition in either gender. Conclusions: Dietary ED was not associated with body composition of children in Southwest China, while dietary EI in boys, not girls, was positively associated with body composition. Reducing dietary energy intake may help to prevent obesity and related diseases in later life among boys living in Southwest China.

The University of Texas M.D. Anderson Cancer Center, Division of Pathology and Laboratory Medicine is committed to providing the best pathology and medicine through: state-of-the art techniques, progressive ground-breaking research, education and training for the clinical diagnosis and research of cancer and related diseases. After surveying the laboratory staff and other hospital professionals, the Department administrators and Human Resource generalists developed a professional development model for Microbiology to support laboratory skills, behavior, certification, and continual education within its staff. This model sets high standards for the laboratory professionals to allow the labs to work at their fullest potential; it provides organization to training technologists based on complete laboratory needs instead of training technologists in individual areas in which more training is required if the laboratory needs them to work in other areas. This model is a working example for all microbiology based laboratories who want to set high standards and want their staff to be acknowledged for demonstrated excellence and professional development in the laboratory. The PDM model is designed to focus on the needs of the laboratory as well as the laboratory professionals.

Full Text Available Typhoon Morakot 2009, with significant southwest monsoon flow, produced a record-breaking rainfall of 2361 mm in 48 hours. This study hopes to improve a statistical typhoon rainfall forecasting method used over the mountain region of Taiwan via an artificial neural network based southwest monsoon enhancement (ANNSME model. Rainfall data collected at two mountain weather stations, ALiShan and YuShan, are analyzed to establish the relation to the southwest monsoon moisture flux which is calculated at a designated sea area southwest of Taiwan. The results show that the moisture flux, with southwest monsoon flow, transported water vapor during the landfall periods of Typhoons Mindulle, Bilis, Fungwong, Kalmaegi, Haitaing and Morakot. Based on the moisture flux, a linear regression is used to identify an effective value of moisture flux as the threshold flux which can enhance mountain rainfall in southwestern Taiwan. In particular, a feedforward neural network (FNN is applied to estimate the residuals from the linear model to the differences between simulated rainfalls by a typhoon rainfall climatology model (TRCM and observations. Consequently, the ANNSME model integrates the effective moisture flux, linear rainfall model and the FNN for residuals. Even with very limited training cases, our results indicate that the ANNSME model is robust and suitable for improvement of TRCM rainfall prediction. The improved prediction of the total rainfall and of the multiple rainfall peaks is important for emergency operation.

Matsuo, Shuji

2014-10-01

It is meaningful to discuss the "present and future of laboratories" for the development of laboratories and education of medical technologists. Laboratory staff must be able to perform urgent high-quality tests and take part in so-called team-based medicine and should be proud of devising systems that efficiently provide laboratory data for all medical staff. On the other hand, there may be staff with a poor sense of professionalism who work no more than is expected and too readily ask firms and commercial laboratories to solve problems. Overwork caused by providing team-based medicine and a decrease in numbers of clinical chemists are concerns. The following are hoped for in the future. Firstly, laboratory staff will become conscious of their own high-level abilities and expand their areas of work, for example, bioscience, proteomics, and reproductive medicine. Secondly, a consultation system for medical staff and patients will be established. Thirdly, clinical research will be advanced, such as investigating unknown pathophysiologies using laboratory data and samples, and developing new methods of measurement. Lastly, it is of overriding importance that staff of laboratory and educational facilities will cooperate with each other to train the next generation. In conclusion, each laboratory should be appreciated, attractive, positive regarding its contribution to society, and show individuality.

To evaluate the impact of continued education provided by an external quality control laboratory on the indicators of internal quality control of cytopathology exams. The internal quality assurance indicators for cytopathology exams from 12 laboratories monitored by the External Quality Control Laboratory were evaluated. Overall, 185,194 exams were included, 98,133 of which referred to the period preceding implementation of a continued education program, while 87,061 referred to the period following this intervention. Data were obtained from the Cervical Cancer Database of the Brazilian National Health Service. Following implementation of the continued education program, the positivity index (PI) remained within recommended limits in four laboratories. In another four laboratories, the PI progressed from below the limits to within the recommended standards. In one laboratory, the PI remained low, in two laboratories, it remained very low, and in one, it increased from very low to low. The percentage of exams compatible with a high-grade squamous intraepithelial lesion (HSIL) remained within the recommended limits in five laboratories, while in three laboratories it progressed from below the recommended levels to >0.4% of the total number of satisfactory exams, and in four laboratories it remained below the standard limit. Both the percentage of atypical squamous cells of undetermined significance (ASC-US) in relation to abnormal exams, and the ratio between ASC-US and intraepithelial lesions remained within recommended levels in all the laboratories investigated. An improvement was found in the indicators represented by the positivity index and the percentage of exams compatible with a high-grade squamous intraepithelial lesion, showing that the role played by the external quality control laboratory in providing continued education contributed towards improving laboratory staff skills in detecting cervical cancer precursor lesions.

Full Text Available The Didactic laboratory, historically, has been a valued progress within the science education, as basic education as higher education. Therefore, we have discussed about the didactic laboratory in a licensure course in biological science. We have performed many semi-structured interviews with teachers from a qualitative research. The objective was the investigation of its use and the possible contribution to the formation of the teachers. The content of the interviews was analyzed through the textual-discursive analysis. There were four categories from the analysis. The first one was the relationship between the didactic laboratory, the curricular projects and the curricular reworking. The second one was the didactic laboratory as another educational formation. The third one was the planning, the developmenting and the evaluating of the laboratorial classes. The last one was the challenges of using the didactic laboratory. The didactic laboratory has intensified the relationship between the theory and the practice. Between the interaction of teacher, students, content, context. Between the execution of activities about conceptual, procedural and attitudinal contents. There is a strong potentiality in didactic laboratory because its dynamic teaching, its learning of specific contents, its didactic of biological science.

2012-01-01

Despite the recognized importance of HIV testing in prevention, care and treatment, HIV testing remains low in China. Millions of female sex workers (FSW) play a critical role in China's escalating HIV epidemic. Limited data are available regarding HIV testing behavior among this at-risk population. This study, based on a cross-sectional survey of 1,022 FSW recruited from communities in Southwest China, attempted to address the literature gap. Our data revealed that 48% of FSW ever took HIV testing; older age, less education, working in higher-income commercial sex venues and better HIV knowledge were associated with HIV testing. Those who never took HIV testing were more likely to engage in high-risk behaviors including inconsistent condom use with clients and stable partners. A number of psychological and structural barriers to testing were also reported. We call for culturally appropriate interventions to reduce HIV risks and promote HIV testing for vulnerable FSW in China.

Audit to assess the quality of communication between operators and technicians in a fixed prosthodontic laboratory: educational and training implications.

Science.gov (United States)

Dickie, J; Shearer, A C; Ricketts, D N J

2014-02-01

This audit aimed to assess the quality of communication between dental students/qualified dentists and dental technicians, increase the percentage of satisfactorily completed laboratory prescriptions and reduce the number of errors that can result from poor communication. A subsidiary aim was to educate students and staff in this respect. An audit of laboratory prescription completion was conducted within Dundee Dental Hospital. Four hundred and eighteen prescriptions for indirect fixed restorations completed by dental undergraduates and qualified staff were audited over a three month period (first audit cycle). Educational reminders on laboratory prescriptions were then provided to undergraduates and qualified staff, a further three hundred and twenty-two prescriptions were audited (second audit cycle) and compared with the first cycle. Satisfactorily completed prescriptions increased from 28% to 43% following basic educational intervention. However, this percentage still signifies a poor level of completion and the need for improvement. Some aspects of the prescription were completed better than others, but overall the standard remained poor with a significant number failing to comply with guidelines set by the UK General Dental Council, the European Union's Medical Devices Directive and the British Society for Restorative Dentistry (BSRD). Further undergraduate and staff training on laboratory prescription writing will be necessary through staff training events and developments in the undergraduate curriculum. © 2013 John Wiley & Sons A/S.

To understand the infection status and main risk factors of soil-transmitted nematodes in southwest China so as to provide the evidence for making the control programs for soil-transmitted nematodiasis. The prevalence of soil-transmitted nematode infections was determined by Kato-Katz technique and influencing factors were surveyed by using a standardized questionnaire, and in part of the children, the examination of Enterobius vermicularis eggs was performed by using the cellophane swab method. The relationship between soil-transmitted nematode infections and influencing factors was analyzed by the multiple probit estimated method. A total of 1 707 children were examined, with a soil-transmitted nematode infection rate of 22.2%, the crowd infection rates ofAscaris lumbricoides, hookworm, and Trichuris trichiura were 16.0%, 3.8% and 6.6% respectively and 495 children were examined on Enterobius vermicularis eggs, with the infection rate of 5.1%. The results of probit estimated analysis suggested that the effects of 4 factors on soil-transmitted nematode infections were significant (all P values were less than 0.05), namely the number of sib, educational level of mother, drinking unboiled water and raising livestock and poultry. Among the factors above, the educational level of mother could reduce the probability of infection (ME = -0.074), while the number of sib, drinking unboiled water and raising livestock and poultry could increase the probability of the infections (with ME of 0.028, -0.112 and 0.080, respectively). Soil-transmitted nematode infection rates are still in a high level for children in southwest poor areas of China, with Ascaris lumbricoides as a priority. The changes of children's bad health habits, raising livestock and poultry habits, and implementing the health education about parasitic diseases in mothers would be of great significance for the prevention and control of soil-transmitted nematodiasis.

Le, Cai; Rong, Su; Dingyun, You; Wenlong, Cui

2016-11-01

This study examines how socioeconomic factors are associated with prevalence and self-management of diabetes among ethnic minority groups in the rural Yunnan province, which has the most ethnic minority groups per province in southwest China. A cross-sectional survey was carried out in 2014 in a rural southwest population consisting of 5532 consenting individuals aged ⩾35years. Information about participants' demographic characteristics, as well as diabetes diagnosis, treatment, and self-management behaviors, were obtained using a standard questionnaire. Fasting blood sugar levels were recorded for each individual. A socioeconomic position (SEP) index was constructed using principal component analysis. The age-standardized prevalence of diabetes in the study population was 4.8%. In persons with diabetes, 23.1% regularly self-monitored blood glucose, 43.2% adhered to taking prescribed anti-diabetic drugs or insulin injections, and 63.1% took at least one measure to control blood glucose. Individual educational level was found to be negatively associated with the prevalence of diabetes, whereas individuals with greater household assets and higher SEP were more likely to be suffered from diabetes. Persons with diabetes with greater household assets, higher level of education, and higher SEP had a greater probability of regularly self-monitoring blood glucose, compliance to prescribed medicines, and taking measures to control diabetes. Access to medical services was positively associated with regularly self-monitoring blood glucose and compliance to prescribed medicines. Socioeconomic disparities in diabetes prevalence and self-management do exist. Future interventions to further control diabetes and improve diabetes management must be tailored to address socioeconomic factors. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

A Regional Water Resource Planning Model to Explore the Water-Energy Nexus in the American Southwest

Science.gov (United States)

Flores-Lopez, F.; Yates, D.; Purkey, D.; Huber-lee, A. T.

2011-12-01

The power sector withdraws substantial cooling water for electric generation in the United States and is thus heavily dependent on available water resources. Changes in water supplies and water quality may impact the reliability of power generation. This research intends to guide energy policy and decision making, leading to reduced greenhouse gas emission and avoiding unintended consequences related to water management in the context of future decisions around type and location of energy generation. It is recognized that different energy management strategies will have different water management implications that extend from the local, to the regional, and ultimately to the national scale. Further, the importance of these impacts will be defined by the characteristics of individual water systems within which energy management strategies are implemented. The Water Evaluation and Planning (WEAP) system was employed to represent the water resource systems of the American Southwest, where various energy management strategies could be represented within a broad water management context, but with regional specificity. A point of convergence for the American Southwest is Southern California, which relies on water transfers from both the Sacramento/San Joaquin system and the Colorado River systems. The reality is that the water systems of the Los Angeles/San Diego system are connected to those of the San Francisco Bay Area, the Central Valley of California, Central Arizona, Metropolitan Las Vegas, the Salt Lake Valley, the Rio Grande Valley, the Front Range of the Rockies, and in fact, to the borders of Kansas, Nebraska, Texas, and Mexico through Interstate and International Compacts. The Southwest WEAP application was developed to represent the water management implications of different energy and water management strategies and development pathways under current and future conditions. The energy assumptions are derived from the National Renewable Energy Laboratory (NREL

Technological choice and change in the Southwest Bath in the Athenian Agora

Directory of Open Access Journals (Sweden)

Artz, James

2012-04-01

Full Text Available During its five architectural phases, the Southwest bath in the Athenian Agora changes from a Greek-style bath into a Roman-style bath. This article will focus on the first two phases, when Roman elements begin to be incorporated into the traditional forms of Greek bath architecture – particularly, a hypocaust floor system and a concrete vaulted ceiling built into a traditional Greek tholos bath. After describing these architectural features and analyzing the techniques used in their construction, I will examine possible sources of influence on the design and construction of the Southwest baths. The Roman army, citizenry, and workmen could all have potentially affected the incorporation of Roman bathing technologies and building techniques into the Southwest bath. The available evidence, however, indicates that the most likely source of influence is Roman workmen, who were employed in large numbers for the numerous building projects underway in Augustan Athens.

Upscaling Ameriflux observations to assess drought impacts on gross primary productivity across the Southwest

Both satellite observations and eddy covariance estimates provide crucial information about the Earth's carbon, water and energy cycles. Continuous measurements from flux towers facilitate exploration of the exchange of carbon dioxide, water and energy between the land surface and the atmosphere at fine temporal and spatial scales, while satellite observations can fill in the large spatial gaps of in-situ measurements and provide long-term temporal continuity. The Southwest (Southwest United States and Northwest Mexico) and other semi-arid regions represent a key uncertainty in interannual variability in carbon uptake. Comparisons of existing global upscaled gross primary production (GPP) products with flux tower data at sites across the Southwest show widespread mischaracterization of seasonality in vegetation carbon uptake, resulting in large (up to 200%) errors in annual carbon uptake estimates. Here, remotely sensed and distributed meteorological inputs are used to upscale GPP estimates from 25 Ameriflux towers across the Southwest to the regional scale using a machine learning approach. Our random forest model incorporates two novel features that improve the spatial and temporal variability in GPP. First, we incorporate a multi-scalar drought index at multiple timescales to account for differential seasonality between ecosystem types. Second, our machine learning algorithm was trained on twenty five ecologically diverse sites to optimize both the monthly variability in and the seasonal cycle of GPP. The product and its components will be used to examine drought impacts on terrestrial carbon cycling across the Southwest including the effects of drought seasonality and on carbon uptake. Our spatially and temporally continuous upscaled GPP product drawing from both ground and satellite data over the Southwest region helps us understand linkages between the carbon and water cycles in semi-arid ecosystems and informs predictions of vegetation response to future

Full Text Available Objective: To explore the effect of a school-family-individual (SFI multi-level education intervention model on knowledge and attitudes about accidental injuries among school-aged children to improve injury prevention strategies and reduce the incidence of pediatric injuries. Methods: The random sample of rural school-aged children were recruited by using a multistage, stratified, cluster sampling method in Zunyi, Southwest China from 2012 to 2014, and 2342 children were randomly divided into intervention and control groups. Then children answered a baseline survey to collect knowledge and attitude scores (KAS of accidental injuries. In the intervention group, children, their parents/guardians and the school received a SFI multi-level education intervention, which included a children’s injury-prevention poster at schools, an open letter about security instruction for parents/guardians and multiple-media health education (Microsoft PowerPoint lectures, videos, handbooks, etc. to children. Children in the control group were given only handbook education. After 16 months, children answered a follow-up survey to collect data on accidental injury types and accidental injury-related KAS for comparing the intervention and control groups and baseline and follow-up data. Results: The distribution of gender was not significantly different while age was different between the baseline and follow-up survey. At baseline, the mean KAS was lower for the intervention than control group (15.37 ± 3.40 and 18.35 ± 5.01; p < 0.001. At follow-up, the mean KAS was higher for the intervention than control group (21.16 ± 3.05 and 20.02 ± 3.40; p < 0.001. The increase in KAS in the intervention and control groups was significant (p < 0.001; KAS: 5.79 vs. 1.67 and suggested that children’s injury-related KAS improved in the intervention group. Moreover, the KAS between the groups differed for most subtypes of incidental injuries (based on International

2015-10-01

Continuous advances in medical laboratory technology have driven major changes in the practice of laboratory medicine over the past two decades. The importance of the overall quality of a medical laboratory has been ever-increasing in order to improve and ensure the quality and safety of clinical practice by physicians in any type of medical facility. Laboratory physicians and professional staff should challenge themselves more than ever in various ways to cooperate and contribute with practicing physicians for the appropriate utilization of laboratory testing. This will certainly lead to a decrease in inappropriate or unnecessary laboratory testing, resulting in reducing medical costs. In addition, not only postgraduate, but also undergraduate medical education/training systems must be markedly innovated, considering recent rapid progress in electronic information and communication technologies.

Recent Developments in Game-Based Virtual Reality Educational Laboratories Using the Microsoft Kinect

Directory of Open Access Journals (Sweden)

Mingshao Zhang

2018-01-01

Full Text Available Virtual Reality (VR is a well-known concept and has been proven to be beneficial in various areas. However, several disadvantages inherent in VR prevent its broad deployment in the educational arena. These limitations include non-realistic representation, lack of customizability and flexibility, financial feasibility, physical and psychological discomforts of the users, simulator sickness, etc. In this paper, an innovative method that uses the Microsoft Kinect as an essential component for developing game-based VR educational laboratories is presented. This technique addresses three different aspects. First, it represents an efficient method for creating the VE using the Kinect as a measuring tool. Second, the Kinect is employed as a substitute DAQ system for acquiring range data and tracking the motion of objects of interest. At last, the Kinect serves as a novel human-computer interface for tracking the users’ entire body motion and recognizing their voices. Using the method described here, three major aspects of educational VR development can be accomplished with an inexpensive and commercially available Kinect.

Experiences with fast breeder reactor education in laboratory and short course settings

Waltar, A.E.

1983-01-01

The breeder reactor industry throughout the world has grown impressively over the last two decades. Despite the uncertainties in some national programs, breeder reactor technology is well established on a global scale. Given the magnitude of this technological undertaking, there has been surprisingly little emphasis on general breeder reactor education - either at the university or laboratory level. Many universities assume the topic too specialized for including appropriate courses in their curriculum - thus leaving students entering the breeder reactor industry to learn almost exclusively from on-the-job experience. The evaluation of four course presentations utilizing visual aids is presented

Swarms of earthquakes at the head of the Southwest Rift Zone on Kīlauea Volcano, Hawai´i, reveal an interaction of normal and strike-slip faulting associated with movement of Kīlauea's south flank. A relocated subset of earthquakes between January 2012 and August 2014 are highly focused in space and time at depths that are coincident with the south caldera magma reservoir beneath the southern margin of Kīlauea Caldera. Newly calculated focal mechanisms are dominantly dextral shear with a north-south preferred fault orientation. Two earthquakes within this focused area of seismicity have normal faulting mechanisms, indicating two mechanisms of failure in very close proximity (10's of meters to 100 m). We suggest a model where opening along the Southwest Rift Zone caused by seaward motion of the south flank permits injection of magma and subsequent freezing of a plug, which then fails in a right-lateral strike-slip sense, consistent with the direction of movement of the south flank. The seismicity is concentrated in an area where a constriction occurs between a normal fault and the deeper magma transport system into the Southwest Rift Zone. Although in many ways the Southwest Rift Zone appears analogous to the more active East Rift Zone, the localization of the largest seismicity (>M2.5) within the swarms to a small volume necessitates a different model than has been proposed to explain the lineament outlined by earthquakes along the East Rift Zone.

Considering Alappuzha Mud Bank in the southern Kerala coast as a typical case of biologically productive Mud Banks that form along the southwest coast of India during the Southwest Monsoon (June - September), the present study addresses several pertinent missing links between the physical environment in Mud Banks and their influence on plankton stock. This study showed that very strong coastal upwelling prevails in the entire study domain during the Southwest Monsoon, which manifests itself in the form of significantly cool, hypoxic and nitrate-rich waters surfacing near the coast. The upwelled water persisting throughout the Southwest Monsoon period was found to have fuelled the exceptionally high phytoplankton stock in the entire study area, including the Mud Bank region. Having accepted that Mud Banks are special because of the calm sea surface conditions and relatively high turbidity level in the water column around them, the present study showed that except at points close to the sea bottom, turbidity level in the Alappuzha Mud Bank was below the critical level to inhibit the plankton stock. The suspended sediments that form in the Mud Bank occasionally could be attributed to the disturbance of the bottom fluid muddy layer and their vertical spurts.

This study was conducted in order to estimate the economic burden of diabetes in a given year in rural Yunnan province of China, including direct, indirect and intangible costs. A cross-sectional survey was conducted in rural southwest China in early 2011 among 9396 consenting individuals aged ≥ 18 years. Information on participants' demographic characteristics, and economic consequences and related aspects of diabetes were obtained using a standard questionnaire. Fasting blood sugar level was also measured for each individual. Years of life lost (YLL) due to diabetes was estimated using medical death certificates. A prevalence-based cost-of-illness method was used to estimate the economic burden of diabetes. The overall prevalence and YLL of diabetes was 6.5% and 1168.1 years in the study population, respectively. Total cost of illness related to diabetes was estimated to be $46.8 million. Mean unit direct medical costs, direct non-medical costs, morbidity costs, mortality costs, intangible costs, and cost of illness were $863.2, $44.6, $59.7, $7797.7, $936.2, and $9686.6, respectively. Direct costs accounted for the largest proportion of the economic costs of diabetes. Age was positively associated with direct costs whereas negatively associated with indirect costs. Patients aged 45-59 years incurred the highest intangible costs. Both indirect and intangible costs increased with level of education. Diabetes is a major public health problem in terms of morbidity and economic burden in rural southwest China. The region should increase investment in the further control of diabetes, and improvement of patient quality of life. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Although laboratory medicine practise varies across the European Union's (EU) member states, the extent of overlap in scope is such that a common syllabus describing the education and training associated with high-quality, specialist practise can be identified. In turn, such a syllabus can help define the common set of skills, knowledge and competence in a Common Training Framework (CTF) for non-medical Specialists in Laboratory Medicine under EU Directive 2013/55/EU (The recognition of Professional Qualifications). In meeting the requirements of the directive's CTF patient safety is particularly enhanced when specialists seek to capitalise on opportunities for free professional migration across EU borders. In updating the fourth syllabus, the fifth expands on individual discipline requirements, new analytical techniques and use of statistics. An outline structure for a training programme is proposed together with expected responsibilities of trainees and trainers; reference is provided to a trainee's log book. In updating the syllabus, it continues to support national programmes and the aims of EU Directive 2013/55/EU in providing safeguards to professional mobility across European borders at a time when the demand for highly qualified professionals is increasing in the face of a disparity in their distribution across Europe. In support of achieving a CTF, the syllabus represents EFLM's position statement for the education and training that underpins the framework.

Widening higher education participation in rural communities in England: An anchor institution model

Science.gov (United States)

Elliott, Geoffrey

2018-02-01

Against a United Kingdom policy background of attempts to widen higher education participation in a socially inclusive direction, this article analyses theory, policy and practice to understand why past efforts have had limited success and to propose an alternative: an "anchor institution" model. A university and a private training provider were the principal partners in this venture, known as the South-West Partnership (pseudonym); the model was developed by them to meet the particular needs of mature female students who want and/or need to study part-time in a rural, coastal and isolated area of south-west England. While the concept of "anchor institutions" has previously been used in government social policy, and in higher education to promote knowledge transfer, it has not yet been adopted as a method for widening participation. The research study presented in this article investigated the effectiveness of the model in widening higher education participation in the context of the South-West Partnership. The study was conducted within an interpretivist theoretical framework. It accessed student voices to illustrate the character of education required to widen participation in vocational higher education by mature female students in rural communities, through semi-structured qualitative interviews on a range of topics identified from relevant theoretical literature, and by drawing on the research team's professional knowledge and experience. These topics included student aspirations and career destinations, motivations, access, learning experiences, and peer and tutor support. It is hoped the findings will inform the future development of adult vocational higher education provision in rural areas, where opportunities have been limited, and encourage further application of the anchor institution model for widening participation elsewhere.

Coastal upwelling and mud banks are two oceanographic processes concurrently operating along certain stretches of the southwest (Kerala) coast of India during the Southwest Monsoon period (June-September), facilitating significant enhancement in plankton biomass. Mud banks have scientific and societal attention from time immemorial, predominantly due to the large fisheries associated with them. In this paper, for the first time, the specific biophysical roles of these oceanographic processes have been discriminated, based on a focused 18 weekly/fortnightly time-series study (April to September 2014) in a mud bank-upwelling area (off Alappuzha, southwest coast of India). In conjunction with standard hydrographical and satellite remote sensing data, we utilised a FlowCAM to track the biophysical linkage in terms of plankton composition abundance and size structure at three locations (M1, M2 and M3) in the study area. During the Pre-Southwest Monsoon (April-May), the entire study area was warmer with low nitrate concentration in the surface waters, which caused lower biomass of autotrophs compared to the Southwest Monsoon (June-September). By the onset of the Southwest Monsoon (June), drastic hydrographical transformations took place in the study domain due to the Coastal upwelling, reflected as the surfacing of significantly cool, high nutrient and hypoxic waters. Concurrently, mud bank formed at location M2 due to the presence of relatively high-suspended sediments in the region, creating a localised calm environment conducive for fishing activities. In response to the hydrographical transformations in the entire study area during the Southwest Monsoon, the autotrophic plankton biomass and size structure experienced significant change. The micro-autotrophs biomass that was low during the Pre-Southwest Monsoon (av. 0.33 ± 0.2 mgC L- 1 at surface and av. 0.07 ± 0.04 mgC L- 1 at subsurface) noticeably increased during the Southwest Monsoon (av. 1.6 ± 0.4 mgC L- 1 at

Magma Supply of Southwest Indian Ocean: Implication from Crustal Thickness Anomalies

Science.gov (United States)

Chiheng, L.; Jianghai, L.; Huatian, Z.; Qingkai, F.

2017-12-01

The Southwest Indian Ridge (SWIR) is one of the world's slowest spreading ridges with a full spreading rate of 14mm a-1, belonging to ultraslow spreading ridge, which are a novel class of spreading centers symbolized by non-uniform magma supply and crustal accretion. Therefore, the crustal thickness of Southwest Indian Ocean is a way to explore the magmatic and tectonic process of SWIR and the hotspots around it. Our paper uses Residual Mantle Bouguer Anomaly processed with the latest global public data to invert the relative crustal thickness and correct it according to seismic achievements. Gravity-derived crustal thickness model reveals a huge range of crustal thickness in Southwest Indian Ocean from 0.04km to 24km, 7.5km of average crustal thickness, and 3.5km of standard deviation. In addition, statistics data of crustal thickness reveal the frequency has a bimodal mixed skewed distribution, which indicates the crustal accretion by ridge and ridge-plume interaction. Base on the crustal thickness model, we divide three types of crustal thickness in Southwest Indian Ocean. About 20.31% of oceanic crust is 9.8km thick as thick crust. Furthermore, Prominent thin crust anomalies are associated with the trend of most transform faults, but thick crust anomalies presents to northeast of Andrew Bain transform fault. Cold and depleted mantle are also the key factors to form the thin crust. The thick crust anomalies are constrained by hotspots, which provide abundant heat to the mantle beneath mid-ocean ridge or ocean basin. Finally, we roughly delineate the range of ridge-plume interaction and transform fault effect.

In a climate of tight fusion research and teaching laboratory budgets, it has become necessary to utilize equipment obtained for research purposes in the teaching program. Likewise, it is desirable to use plasma research equipment from nonfusion projects to support basic understanding of general plasma concepts. Multiple experiments can also be done on a single device. The plasma laboratory that has been developed at North Carolina State University in the last 4 yr incorporates all of the aforementioned ideas to support a 3-credit-hour hands-on laboratory course for graduate students. Incorporating teaching and research into the fusion plasma laboratory maximizes the resources and gives students experience on actual research tools. 2 refs

In order to understand the characteristics of PM₂.₅ pollution in the atmosphere of Chengdu southwest suburb, PM₂.₅ particles in Chengdu southwest suburb were collected and analyzed from March 18 to March 31st, 2015. The results showed that the daily average concentration of PM₂.₅ in the southwest suburb of Chengdu reached 121.21 µg · m⁻³, and the average daily concentration of 24 samples in 31 PM₂.₅ samples was over 75 µg · m⁻³, the daily excessive rate was 77%, indicating the PM₂.₅ pollution in the study area was serious in March. When studying the relationship between atmospheric and meteorological factors, it was found that there was a significant index correlation between PM₂.₅ concentration and atmospheric visibility, and it had a positive correlation with temperature and humidity, but the correlation was not obvious. NH₄⁺ (16.24%), SO₄²- (12.58%) and NO₃⁻ (9.91%) were dominant in PM₂.₅ The ratio of NO₃⁻/SO₄²⁻ was 0.77, which indicated that the pollution of stationary sources in the southwest suburb was more severe than that of mobile sources. Organic carbon (OC)/elemental carbon (EC) ratios were higher than 2, which indicated the existence of second organic carbon (SOC). Using OC/EC ratio method to estimate the concentration of SOC, it was found that the average concentration of SOC in the southwest suburb of Chengdu in March was 3.49 µ · m⁻³, and the contribution rate of OC was 20.6%, which showed that the main source of OC in the southwest suburb of Chengdu was primary discharge. The correlation analysis of OC and EC showed that the correlation coefficient reached 0.95, indicating that the OC and EC sources were similar and relatively stable, and there was a great impact of local source emissions on Chengdu southwest suburb in spring, and primary discharge played a dominant role, while the contribution of SOC to OC was relatively small, which was consistent with the SOC characteristics obtained

In order to contribute to improved healthcare quality through patient-centered care, laboratory professionals at all levels of practice must be able to recognize the connection between non-analytical factors and laboratory analysis, in the context of patient outcomes and quality improvement. These practices require qualities such as critical thinking (CT), teamwork skills, and familiarity with the quality improvement process, which will be essential for the development of evidence-based laboratory science practice. Performance tasks (PT) are an educational strategy which can be used to teach and assess CT and teamwork, while introducing Medical Laboratory Science (MLS) students at both baccalaureate and advanced-practice levels to the concepts of quality improvement processes and patient outcomes research. PT presents students with complex, realistic scenarios which require the incorporation of subject-specific knowledge with competencies such as effective team communication, patient-centered care, and successful use of information technology. A PT with assessment rubric was designed for use in a baccalaureate-level MLS program to teach and assess CT and teamwork competency. The results indicated that, even when students were able to integrate subject-specific knowledge in creative ways, their understanding of teamwork and quality improvement was limited. This indicates the need to intentionally teach skills such as collaboration and quality system design. PT represent one of many strategies that may be used in MLS education to develop essential professional competencies, encourage expert practice, and facilitate quality improvement.

Jatropha curcas L. (JCL) is believed to be the most promising tree species used to produce biodiesel in China. Due to its abundant marginal land resource and good meteorological conditions, Southwest China is the major region to develop JCL. With Southwest China being taken as the study area in this paper, multi-factor comprehensive analysis is used to identify marginal land resources suitable to JCL plantation and make suitability assessment, thus obtaining their spatial distribution, suitability degree and total amount. With life cycle analysis (LCA), the life cycle net energy and greenhouse gas emission reduction capacity of marginal land resources with different suitability degrees used to produce biodiesel are investigated. Based on the research results, the life cycle model is expanded to obtain the potentiality of total net energy production and greenhouse gas emission reduction of large-scale plantation of JCL in southwest China. The results show that the area of land resources suitable and moderately suitable for JCL plantation is 1.99 × 10 6 ha and 5.57 × 10 6 ha, respectively. If all of these land resources are put into use, the maximum net production potential of biodiesel from JCL would be 1.51 × 10 8 GJ/a, and the total greenhouse gas emission reduction capacity 1.59 × 10 7 t/a in Southwest China. -- Highlights: •A LCA based approach for assessing net energy potential of Jatropha curcas L. was presented. •The net production potential of biodiesel from JCL is 1.51 × 10 8 GJ/a in Southwest China. •The total GHG emission reduction capacity from JCL is 1.59 × 10 7 t/a in Southwest China

Olive trees, originated from Mediterranean, have been cultivated in China for decades and show great adaption to local environment. However, research on this topic is limited. In this study, the major qualitative characteristics and changes of olive grown in southwest China were investigated. The results showed that oil accumulated during fruit development and reached its maximum value when fruit had fully ripened. Phenolic and flavonoid contents increase rapidly in the early growth stage (0-90 DAFB) and then begin to decrease as fruit ripens. Compared with olive from the Mediterranean, olive from China has special characteristics: higher moisture content in the fruit combined with lower percentages of unsaturated fatty acids and oil content. This is due to southwest China's climate which is wetter and cooler compared to the Mediterranean. Our study suggests that southwest China's higher annual rainfall might contribute to higher fruit moisture content while its low temperatures would be conducive to higher unsaturated fatty acid levels in the fruit.

Tree- and Stand-Level Thinning Effects on Growth of European Beech (Fagus sylvatica L. on a Northeast- and a Southwest-Facing Slope in Southwest Germany

2015-09-01

Full Text Available Anticipated changes in climate and research findings on the drought sensitivity of beech have triggered controversial discussions about the future of European beech. We investigated the growth response of beech on the tree- and stand-level in mature stands to three different thinning intensities (no thinning, strong thinning, very strong thinning on a northeast- and southwest-facing slope in Southwest Germany. Linear mixed-effects models were formulated to describe effects on growth parameters on the tree- and stand-level (diameter, height, basal area, volume. At the stand-level, the stand basal area increment and stand volume increment were lower on the thinned plots. At the tree-level, the basal area increment significantly increased with increasing thinning intensity. The growth of individual trees was also influenced by initial tree size, the size-related rank of the tree within a stand, and by the aspect of the site. Our data indicate that growth of European beech is impaired on the southwest-facing slope with a warmer and drier climate and that a very strong thinning regime applied at advanced age can accelerate growth of European beech trees even on the warmer and drier site. Our findings, therefore, imply that in a warmer climate intensive thinning may also represent an important adaptive forest management measure in European beech stands.

Estimating Probable Maximum Precipitation by Considering Combined Effect of Typhoon and Southwesterly Air Flow

Directory of Open Access Journals (Sweden)

Cheng-Chin Liu

2016-01-01

Full Text Available Typhoon Morakot hit southern Taiwan in 2009, bringing 48-hr of heavy rainfall [close to the Probable Maximum Precipitation (PMP] to the Tsengwen Reservoir catchment. This extreme rainfall event resulted from the combined (co-movement effect of two climate systems (i.e., typhoon and southwesterly air flow. Based on the traditional PMP estimation method (i.e., the storm transposition method, STM, two PMP estimation approaches, i.e., Amplification Index (AI and Independent System (IS approaches, which consider the combined effect are proposed in this work. The AI approach assumes that the southwesterly air flow precipitation in a typhoon event could reach its maximum value. The IS approach assumes that the typhoon and southwesterly air flow are independent weather systems. Based on these assumptions, calculation procedures for the two approaches were constructed for a case study on the Tsengwen Reservoir catchment. The results show that the PMP estimates for 6- to 60-hr durations using the two approaches are approximately 30% larger than the PMP estimates using the traditional STM without considering the combined effect. This work is a pioneer PMP estimation method that considers the combined effect of a typhoon and southwesterly air flow. Further studies on this issue are essential and encouraged.

The impact of Southwest Airline's contribution to atmospheric Carbon Dioxide and Nitrous Oxide totals

Science.gov (United States)

Wilkerson, Cody L.

Over the last century, aviation has grown to become an economical juggernaut. The industry creates innovation, connects people, and maintains a safety goal unlike any other field. However, as the world becomes more populated with technology and individuals, a general curiosity as to how human activity effects the planet is becoming of greater interest. This study presents what one domestic airline in the United States, Southwest Airlines, contributes to the atmospheric make-up of the planet. Utilizing various sources of quantifiable data, an outcome was reached that shows the amount of Carbon Dioxide and Nitrous Oxide produced by Southwest Airlines from 2002 to 2013. This topic was chosen due to the fact that there are no real quantifiable values of emission statistics from airlines available to the public. Further investigation allowed for Southwest Airlines to be compared to the overall Carbon Dioxide and Nitrous Oxide contributions of the United States for the year 2011. The results showed that with the absence of any set standard on emissions, it is vital that one should be established. The data showed that the current ICAO standard emission values showed a higher level of emissions than when Southwest Airline's fleet was analyzed using their actual fleet mix.

2010-01-01

This study has assembled a climatology of Southwest Pacific explosively developing cyclones, based on the European Centre for Medium-Range Weather Forecasts' ERA-Interim reanalysis data, over the 21-year period from 1989 to 2009. The recently developed 'combined explosive' expression, a refinement of the 'relative explosive' criterion, was used to identify cyclones deemed explosive with respect to both the drop in central pressure and the climatological pressure gradient. Over the period of analysis, 47 explosive cyclones were identified within the Southwest Pacific, equating to an average of 2.2 explosive events per year. Seasonally, explosive cyclones are most frequent during the winter months, while least frequent during the summer. Two case explosive systems are briefly considered, with their corresponding measures of intensity and scale placed into climatological perspective.

Organized convection over southwest peninsular India during the pre-monsoon season

Science.gov (United States)

Sreelekha, P. N.; Babu, C. A.

2018-03-01

The paper addresses observational aspects of widespread rain associated with the organized convection that forms over the southwest peninsular India during the pre-monsoon season. The evolution of the cloud band over the equatorial region, its northward propagation, development of cross equatorial flow near the Somalia coast, and appearance of equatorial westerly wind resemble closely to that of the monsoon organized convection. Low-level convergence, cyclonic vorticity, and ascending motion are other major characteristics of the cloud bands associated with the pre-monsoon organized convection which exhibits similarity with that of monsoon. The ascending motion plays vital role on the formation of cloud band that produces widespread rainfall persisting for more than a week. The vertical shear of meridional winds is found to co-exist with precipitation over the Arabian Sea off the southwest peninsular India. The velocity potential values derived from the winds at 850 and 200 hPa levels confirm the rising motion on the basis of low-level convergence and upper level divergence. Also, shifting of ascending limb of the local Hadley circulation to the north of the equator is observed during the days of the presence of organized convection over the southwest peninsular region. Noticeable shift in the Walker circulation rising limb is also identified during the same time.

We present an update on our developing Virtual Ice Sheet Laboratory (VISL). Geared to K-12 classrooms and the general public, VISL's main goal is to improve climate literacy, especially in regards to the crucial role of the polar ice sheets in Earth's climate and sea level. VISL will allow users to perform guided experiments using the Ice Sheet System Model (ISSM), a state-of-the-art ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine that simulates the near-term evolution of the ice sheets on Greenland and Antarctica. VISL users will access ISSM via a graphical interface that can be launched from a web browser on a computer, tablet or smart phone. Users select climate conditions and run time by moving graphic sliders then watch how a given region evolves in time under those conditions. Lesson plans will include conceptual background, instructions for table top experiments related to the concepts addressed in a given lesson, and a guide for performing model experiments and interpreting their results. Activities with different degrees of complexity will aim for consistency with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12), although they will not be labeled as such to encourage a broad user base. Activities will emphasize the development of physical intuition and critical thinking skills, understanding conceptual and computational models, as well as observation recording, concept articulation, hypothesis formulation and testing, and mathematical analysis. At our present phase of development, we seek input from the greater science education and outreach communities regarding VISL's planned content, as well as additional features and topic areas that educators and students would find useful.

Cruise data sets, satellite remote sensing observations, and model data analyses are combined to highlight the existence of a coastal surface poleward flow in the southwest of Madagascar: the Southwest MAdagascar Coastal Current (SMACC). The SMACC is a relatively shallow (water surface signature of the SMACC extends from 22°S (upstream) to 26.4°S (downstream). The SMACC exhibits a seasonal variability: more intense in summer and reduced in winter. The average volume transport of its core is about 1.3 Sv with a mean summer maximum of 2.1 Sv. It is forced by a strong cyclonic wind stress curl associated with the bending of the trade winds along the southern tip of Madagascar. The SMACC directly influences the coastal upwelling regions south of Madagascar. Its existence is likely to influence local fisheries and larval transport patterns, as well as the connectivity with the Agulhas Current, affecting the returning branch of the global overturning circulation.

Objective:Male breast cancer is a rare disease with an incidence of about 1%of breast cancers in USA, but relatively lack of the information of male breast cancer in China, especial y in Southwest of China, led us to study its incidence trends. Methods:Chongqing is one of the biggest and the most important areas that is located in Southwest of China. There are around 31.4 mil ion people who live in approximate 82 402.95 km2 area of Chongqing. Data about breast cancer patients registered in the Center for Disease Prevention and Control of Chongqing (China) were statistical y col ected from 187 hospi-tals, about 58 hospitals in city and 129 hospitals in country, and over 6.2 mil ion people were studied every year. It was tried to represent al the people in vil ages and cities in Chongqing, China. Results:The incidence of male breast cancer in Southwest of China ranged from 0.34/100 000 to 1.45/100 000 between 2007 and 2011, while the incidence of female breast cancer ranged from 15.40/100000 to 21.66/100000 at the same time. The rate of male breast cancer to female breast cancer ranged from 0.02:1 to 0.07:1, male breast cancer accounted for 1.96%to 6.5%(with the mean value of 2.9%) of breast cancers in Southwest of China from 2007 to 2010. Conclusion:In Southwest of China male breast cancer accounts for about 2.9%of breast cancers which is higher than that in United States. It is important for policy makers and health manager to seriously consider breast cancer in future plan in Southwest of China.

This study was a retrospective investigation of botulism cases over a period of 18 years following major political and economic changes, addressing the question of whether this disease is still an important health concern in southwest Romania. The medical records of botulism cases were used as the source of data. Patients from five southwest Romanian counties were hospitalized at Victor Babes Hospital of Infectious Diseases in Timisoara during the period 1990-2007. The median annual incidence of botulism cases in southwest Romania decreased from 0.1 per 100 000 persons during 1990-1998, to 0.05 per 100 000 persons during 1999-2007. Most of the cases (18.6%) were diagnosed in 1990, immediately following the communism period. The median age of the patients was 38 years (range 16-73 years); 24 (55.8%) were male; the case fatality rate was 2.3%. A significantly higher incidence rate of 2.7 cases per 100 000 persons occurred in rural areas, even though most of the cases (53.5%) were inhabitants of urban areas. The clinical pattern included: difficulty swallowing (79.1%), double and/or blurred vision (69.8%), dry mouth (60.5%), drooping eyelids (51.2%), vomiting (39.5%), mydriasis (37.2%), constipation (27.9%), abdominal pain (23.3%), and slurred speech (18.6%). All cases were attributed to contaminated food sources, mainly home-prepared traditional pork products. Although the botulism cases decreased over the study period in southwest Romania, this life-threatening disease continues to be an important concern. A strategy addressing individual behaviors in the home is needed to improve food safety. Copyright 2009 International Society for Infectious Diseases. Published by Elsevier Ltd. All rights reserved.

Krupp, E. C.

1994-12-01

Astronomical interpretations of prehistoric rock art have played a significant part in the development of modern archaeoastronomy since 1975, when interest was renewed in the possibility that the Crab supernova explosion of 1054 A.D. was represented in rock art of the American Southwest. (This hypothesis was actually first formulated in 1955.) In the last two decades, a variety of astronomical functions for rock art have been proposed and investigated. These include representation of specific historical celestial events, symbolic representation of elements of celestial myths, star maps, markers for astronomical observing stations markers for celestially tempered shrines, images intended to invoke and exploit cosmo-magical power, seasonally significant light-and-shadow displays. Examples of astronomical connotations in prehistoric rock art from the Southwest and California illustrate the necessity of understanding the culture in any attempt to understand its astronomy.

Full Text Available This paper is devoted to the procedure of realization of the main didactic principle – use visual method which becomes an essential factor of student perception of educational sources. The procedure is realized with series of laboratory works which are based on the principle – “device-computer-software”. The transformers of a physical magnitude into electrical signal are used in laboratory works. The combination of these transformers and a computer form the device which can measure a physical magnitude. The software allows reconstructing a virtual field distribution of this magnitude in area and observing its history. MATLAB is used as software and it provides with computation of different physical processes. The proposed procedure provides with a direct visual method and an indirect one as well. This matter promotes forming future specialists’ professional competence.

Rocky desertification in Southwest China: Impacts, causes, and restoration

Science.gov (United States)

Jiang, Zhongcheng; Lian, Yanqing; Qin, Xiaoqun

2014-05-01

Rocky desertification, which is relatively less well known than desertification, refers to the processes and human activities that transform a karst area covered by vegetation and soil into a rocky landscape. It has occurred in various countries and regions, including the European Mediterranean and Dinaric Karst regions of the Balkan Peninsula, Southwest China on a large scale, and alarmingly, even in tropical rainforests such as Haiti and Barbados, and has had tremendous negative impacts to the environment and social and economic conditions at local and regional scales. The goal of this paper is to provide a thorough review of the impacts, causes, and restoration measures of rocky desertification based on decades of studies in the southwest karst area of China and reviews of studies in Europe and other parts of the world. The low soil formation rate and high permeability of carbonate rocks create a fragile and vulnerable environment that is susceptible to deforestation and soil erosion. Other natural processes related to hydrology and ecology could exacerbate rocky desertification. However, disturbances from a wide variety of human activities are ultimately responsible for rocky desertification wherever it has occurred. This review shows that reforestation can be successful in Southwest China and even in the Dinaric Karst region when the land, people, water, and other resources are managed cohesively. However, new challenges may arise as more frequent droughts and extreme floods induced by global climate change and variability may slow the recovery process or even expand rocky desertification. This review is intended to bring attention to this challenging issue and provide information needed to advance research and engineering practices to combat rocky desertification and to aid in sustainable development.

To review academic dismissals, students' rights in dismissal cases, and several key cases involving academic and disciplinary dismissals. Recent academic literature and legal precedents. Not applicable. Not applicable. Students involved in dismissals are protected under the principles of constitutional law and/or contract law, depending on whether the institution is public or private. The basis for dismissal from educational programs is either academic or disciplinary in nature. In academic dismissals, a student has failed to meet either the cognitive or the noncognitive academic standards of the program. In disciplinary dismissals, a student has violated the institutional rules governing conduct. Policies that affect progress in the program and the dismissal process should be published and distributed to students, as well as reviewed for consistency with institutional policies. The amount of documentation needed in the defense of a dismissal decision has not been specified, but, in general, more is better. Procedures are suggested as a guide to dismissals in clinical laboratory programs.

The relative grazing impact of Noctiluca scintillans (hereafter referred only Noctiluca) and copepods (Acrocalanus gracilis, Paracalanus parvus, Acartia danae and Oithona similis) on the phytoplankton community in an upwelling-mudbank environment along the southwest coast India is presented here. This study was carried out during the Pre-Southwest Monsoon (April-May) to the Late Southwest Monsoon (August) period in 2014. During the sampling period, large hydrographical transformation was evident in the study area (off Alappuzha, Southwest coast of India); warmer Pre-Southwest Monsoon water column condition got transformed into cooler and nitrate-rich hypoxic waters during the Southwest Monsoon (June-August) due to intense coastal upwelling. Copepods were present in the study area throughout the sampling period with a noticeable increase in their abundance during the Southwest Monsoon. On the other hand, the first appearance of Noctiluca in the sampling location was during the Early Southwest Monsoon (mid-June) and thereafter their abundance increased towards the Peak Southwest Monsoon. The grazing experiments carried out as per the food removal method showed noticeable differences in the feeding preferences of Noctiluca and copepods, especially on the different size fractions of phytoplankton. Noctiluca showed the highest positive electivity for the phytoplankton micro-fraction (av. 0.49 ± 0.04), followed by nano-fraction (av. 0.17 ± 0.04) and a negative electivity for the pico-fraction (av. -0.66 ± 0.06). In total ingestion of Noctiluca, micro-fraction contribution (83.7%) was significantly higher compared to the nano- (15.7%) and pico-fractions (0.58%). On the other hand, copepods showed the highest positive electivity for the phytoplankton nano-fraction (av. 0.38 ± 0.04) followed by micro- (av. -0.17 ± 0.05) and pico-fractions (av. -0.35 ± 0.05). Similarly, in total ingestion of copepods, nano-fraction (69.7%) was the highest followed by micro

The current understanding of associations between lung disease and military deployment to Southwest Asia, including Iraq and Afghanistan, is both controversial and limited. We sought to clarify the relation between military deployment and biopsy-proven lung disease. Retrospective data were analyzed for military personnel with non-neoplastic lung biopsies evaluated at the Armed Forces Institute of Pathology or Joint Pathology Center (January 2005 to December 2012). Of 391 subjects, 137 (35.0%) had deployed to Southwest Asia prior to biopsy. Compared to non-deployed subjects, those deployed were younger (median age 37 vs. 51 years) with higher representation of African Americans (30.0 vs. 16.9%). Deployed patients were more likely diagnosed with non-necrotizing granulomas (OR 2.4). Non-deployed subjects had higher frequency of idiopathic interstitial pneumonias, particularly organizing pneumonia. Prevalence of small airways diseases including constrictive bronchiolitis was low. This study provides a broader understanding of diversity of biopsy-proven non-neoplastic lung disease as it relates to military deployment to Southwest Asia and importantly did not show an increased prevalence of small airway disease to include constrictive bronchiolitis.

Educational laboratory experiments on chemistry in a nuclear engineering school

International Nuclear Information System (INIS)

Akatsu, E.

1982-01-01

An educational laboratory experiment on radiochemistry was investigated by students in the general course of the Nuclear Engineering School of Japan Atomic Energy Research Institute. Most of them are not chemical engineers, but electrical and mechanical engineers. Therefore, the educational experiment was designed for them by introducing a ''word experiment'' in the initial stage and by reducing the chemical procedure as far as possible. It began with calculations on a simple solvent extraction process-the ''word experiment''--followed by the chemical separation of 144 Pr from 144 Ce with tri-n-butyl phosphate in a nitric acid system and then measurement of the radioactive decay and growth of the separated 144 Pr and 144 Ce, respectively. The chemical procedure was explained by the phenomenon but not by the mechanism of chelation. Most students thought the experiment was an exercise in solvent extraction or radiochemical separation rather than a radioactive equilibrium experiment. However, a pure chemist considered it as a sort of physical experiment, where the chemical procedure was used only for preparation of measuring samples. Another experiment, where 137 Cs was measured after isolation with ammonium phosphomolybdate, was also investigated. The experiment eliminated the need for students who were not chemists to know how to use radioactive tracers. These students appreciated the realization that they could understand the radioactivity in the environmental samples in a chemical frame of reference even though they were not chemists

The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSU's overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratory's focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3

Hairdressers and their apprentices are mostly women in their reproductive years. The social environment in hairdressing salons provides the opportunity to discuss sexual exploits among peers and may influence decisions on sexual behavior. This study was designed to assess the knowledge and use of contraceptives among hairdressers. A structured questionnaire was used to collect information on demographic characteristics and knowledge and use of contraceptive methods among hairdressers in Ibadan, South-west Nigeria. A total of 355 hairdressers were interviewed: 60 apprentices (17%) and 295 qualified hairdressers (83%); 110 (31%) single and 240 (67%) married. They were females aged 15 - 49 years (mean 29 +/- 6.9 years). Some 70% of single women had regular sexual partners. A total of 24 single women (21%) had been pregnant and 20 (18%) had abortions. Some 121 (34%) of the study population were currently using contraceptives: 27 single and 94 married respondents. The prevalence of contraceptive use among sexually active single women was 34%. The condom was the most known and used contraceptive method. The major reasons for non-use of contraceptives were fear of side-effects (23%); need for more children (16%); or respondents were not engaged in sexual activity (12%). Contraceptive use among sexually active single hairdressers is lower than the national average. Workplace educational intervention is needed to prevent unwanted pregnancies and sexually transmitted infections among these young women.

Phylogeographic study of Apodemus ilex (Rodentia: Muridae in Southwest China.

Directory of Open Access Journals (Sweden)

Qi Liu

Full Text Available BACKGROUND: The Mountains of southwest China have complex river systems and a profoundly complex topography and are among the most important biodiversity hotspots in the world. However, only a few studies have shed light on how the mountains and river valleys promote genetic diversity. Apodemus ilex is a fine model for investigating this subject. METHODOLOGY/PRINCIPAL FINDINGS: To assess the genetic diversity and biogeographic patterns of Apodemus ilex, the complete cytochrome b gene sequences (1,140 bp were determined from 203 samples of A. draco/ilex that were collected from southwest China. The results obtained suggested that A. ilex and A. draco are sistergroups and diverged from each other approximately 2.25 million years ago. A. ilex could be divided into Eastern and Western phylogroups, each containing two sub-groups and being widespread in different geographical regions of the southern Hengduan Mountains and the western Yunnan - Guizhou Plateau. The population expansions of A. ilex were roughly from 0.089 Mya to 0.023 Mya. CONCLUSIONS: Our result suggested that A. ilex is a valid species rather than synonym of A. draco. As a middle-high elevation inhabitant, the phylogenetic pattern of A. ilex was strongly related to the complex geographical structures in southwest China, particularly the existence of deep river valley systems, such as the Mekong and Salween rivers. Also, it appears that the evolutionary history of A. ilex, such as lineage divergences and population expansions were strongly affected by climate fluctuation in the Late Pleistocene.

Tyler, Betty M; Liu, Ann; Sankey, Eric W; Mangraviti, Antonella; Barone, Michael A; Brem, Henry

2016-06-01

After over 50 years of scientific contribution under the leadership of Harvey Cushing and later Walter Dandy, the Johns Hopkins Hunterian Laboratory entered a period of dormancy between the 1960s and early 1980s. In 1984, Henry Brem reinstituted the Hunterian Neurosurgical Laboratory, with a new focus on localized delivery of therapies for brain tumors, leading to several discoveries such as new antiangiogenic agents and Gliadel chemotherapy wafers for the treatment of malignant gliomas. Since that time, it has been the training ground for 310 trainees who have dedicated their time to scientific exploration in the lab, resulting in numerous discoveries in the area of neurosurgical research. The Hunterian Neurosurgical Laboratory has been a unique example of successful mentoring in a translational research environment. The laboratory's philosophy emphasizes mentorship, independence, self-directed learning, creativity, and people-centered collaboration, while maintaining productivity with a focus on improving clinical outcomes. This focus has been served by the diverse backgrounds of its trainees, both in regard to educational status as well as culturally. Through this philosophy and strong legacy of scientific contribution, the Hunterian Laboratory has maintained a positive and productive research environment that supports highly motivated students and trainees. In this article, the authors discuss the laboratory's training philosophy, linked to the principles of adult learning (andragogy), as well as the successes and the limitations of including a wide educational range of students in a neurosurgical translational laboratory and the phenomenon of combining clinical expertise with rigorous scientific training.

Laboratory testing in hyperthyroidism.

Grebe, Stefan K G; Kahaly, George J

2012-09-01

The clinical diagnosis of hypo- or hyperthyroidism is difficult (full text available online: http://education.amjmed.com/pp1/272). Clinical symptoms and signs are often non-specific, and there is incomplete correlation between structural and functional thyroid gland changes. Laboratory testing is therefore indispensible in establishing the diagnosis of thyrotoxicosis. Similar considerations apply to treatment monitoring. Laboratory testing also plays a crucial role in establishing the most likely cause for a patient's hyperthyroidism. Finally, during pregnancy, when isotopic scanning is relatively contraindicated and ultrasound is more difficult to interpret, laboratory testing becomes even more important. Copyright © 2012.

Full Text Available Objective: To evaluate the prevalence of parasitic contamination in fast food salads in Ahvaz city, southwest of Iran, in 2016. Methods: In the current study, 150 samples were randomly collected from 150 fast food shops in Ahvaz City, southwest of Iran. The samples were collected in a clean bucket containing deionized water and detergent. After three times washing, the resultant precipitate was examined in terms of parasites using physiological saline as well as the acid fast and the trichrome staining methods. Results: Of 150 samples, 17 (11.33% positive cases were observed, among which 8 (5.34%, 4 (2.66%, 2 (1.34%, 1 (0.67% and 2 (1.34% were observed positive for Entamoeba coli (E. coli, Cryptosporidium, Giardia lambelia, immature oocyst of Coccidia and mites, respectively. Conclusions: The results showed a relatively high prevalence of parasitic infections especially E. coli in fast food salads in Ahvaz, southwest of Iran. Since the parasitic infections can cause malabsorption, severe diarrhea, intestinal obstruction, cholecystitis, liver inflammation, pulmonary and renal complications, health authorities must pay more attention to the health of fast food shops.

Assessing the Sustainability of the Built Environment in Mountainous Rural Villages in Southwest China

Directory of Open Access Journals (Sweden)

Li Wan

2016-02-01

Full Text Available Mountainous rural areas such as those in southwest China are developing rapidly. This requires scientific understanding and a framework for assessing the sustainability of the built environment that is suitable to such areas. At present, no such framework exists. This lack of assessment options has contributed to the unsustainable development of these areas, which has caused a series of environmental, social, and economic problems. This article analyzes existing assessment frameworks, reviews the theory on sustainable rural development as it applies to rural southwest China, and proposes a new assessment framework that is more suitable to this region and others like it. This framework is based on a sustainable development model for rural areas that emphasizes endogenous development; addresses the environmental, social, and economic dimensions of sustainability; and takes the natural and social conditions of mountainous rural areas into account. Our study tested its applicability to rural southwest China and its sensitivity to local conditions and found them to be better than those of existing assessment frameworks.

Southwest British Columbia natural gas supply and deliverability: Discussion paper

International Nuclear Information System (INIS)

1994-02-01

A review is presented of energy in British Columbia, the role of natural gas, and options available to enhance gas supply security in the province's most densely populated area, the southwest. British Columbia has abundant natural gas supplies, and production exceeds domestic demand. In 1992, natural gas supplied ca 25% of total provincial end-use energy requirements, but this share is expected to rise to 30% by 2015. Although some say that the province's natural gas production and transmission system should serve only domestic needs, this would have significant negative impacts. Domestic gas supply policy allows gas consumers to contract their own supplies, but contract security is required. Provincial guidelines allow demand-side programs to compete with supply sources to ensure that the resource profile is achieved at least cost. In the southwest, natural gas demand is projected to increase from 189 PJ in 1991 to 262 PJ by 2005. Most gas supplied to this region comes from northeast British Columbia through pipelines that are generally fully contracted. Short-term deliverability can be a problem, especially in peak winter demand periods. The gas industry's contingency plans for shortages are outlined and alternatives to enhance deliverability to the southwest are assessed, including storage, expansion of the pipeline system, supply curtailment, and peaking supply contracts. Aspects of provincial natural gas planning are discussed, including security of supply and deliverability, economic and environmental impacts, consumer costs, safety, and the public interest. A least-cost option for enhancing deliverability (underground storage and an additional liquefied natural gas plant) is estimated to cost consumers $3.69/GJ over 20 years. 9 figs., 1 tab

Instructional Technology and School Ethos: A Primary School Model in Southwest England

Directory of Open Access Journals (Sweden)

Erik Jon Byker

2014-04-01

Full Text Available The way in which information and communication technology (ICT enhances the dimensions of teaching and student learning is not well understood. As a result, schools and teacher often integrate ICT with little thought to how it could be educationally profitable or pedagogically meaningful. The literature calls for models of primary school ICT integration. This paper reports on a case study of a primary school (or elementary school model of technology integration. Specifically, the case study investigates a public, primary school located in rural Southwest England. In particular, the paper describes how ICT is integrated in a Grade Six classroom in this primary school. Using a mixed-methods research methodology, the study’s data is drawn from 60 participants (n=60, including the school’s teachers and students. The analyses of this study uncovered a strong link between successful ICT integration and school ethos. Furthermore, the study found that along with school ethos the teacher leadership fostered an environment where the integration of ICT can flourish and students are motivated to learn.

Rowland, Kevin C; Joy, Anita

2015-03-01

Reports on the status of dental education have concluded that there is a need for various types of curricular reform, making recommendations that include better integration of basic, behavioral, and clinical sciences, increased case-based teaching, emphasis on student-driven learning, and creation of lifelong learners. Dental schools faced with decreasing contact hours, increasing teaching material, and technological advancements have experimented with alternate curricular strategies. At Southern Illinois University School of Dental Medicine, curricular changes have begun with a series of integrated biomedical sciences courses. During the process of planning and implementing the integrated courses, a novel venue-the gross anatomy laboratory-was used to introduce all Year 1 students to critical thinking, self-directed learning, and the scientific method. The venture included student-driven documentation of anatomical variations encountered in the laboratory using robust scientific methods, thorough literature review, and subsequent presentation of findings in peer review settings. Students responded positively, with over 75% agreeing the experience intellectually challenged them. This article describes the process of re-envisioning the gross anatomy laboratory as an effective venue for small group-based, student-driven projects that focus on key pedagogical concepts to encourage the development of lifelong learners.

The Potential of Non-Formal Laboratory Environments for Innovating the Chemistry Curriculum and Promoting Secondary School Level Students Education for Sustainability

Directory of Open Access Journals (Sweden)

Nicole Garner

2015-02-01

Full Text Available Developing skills and attitudes among students in terms of Education for Sustainable Development (ESD requires that educators address issues of sustainability in both formal and non-formal education. However, up to now, ESD seems to have been insufficiently implemented in secondary science education in many countries in general, and in high school chemistry learning in particular. A lack of suitable experiments, coupled with missing teaching and learning materials and insufficient teacher professional development have been identified as the reasons for this gap. This paper describes a project of innovation and research in the field of ESD for secondary school chemistry education. Within the project, both half- and full-day learning environments have been developed for non-formal, laboratory-based learning of secondary level students at the university. The research-based development focuses on teaching-learning modules which link formal and non-formal learning. The pedagogy employed is both learner-centered and inquiry-based. All the modules focus on sustainability issues in chemistry-related contexts. Data was collected by questionnaires from teachers and students both prior to and after the visit of the non-formal learning environment. Likert-items were analyzed statistically and the evaluation of the open-ended questions was done by Qualitative Content Analysis. An overview of the project, a case from the non-formal laboratory setting, and findings from accompanying research and evaluation are discussed in this paper. Potential impacts on teacher professional development and curriculum innovation are also outlined.

Southwest China represents one of the largest continuous karst regions in the world. It is estimated that around 1.7 million people are heavily dependent on water derived from karst springs in southwest China. However, there is a limited amount of water supply in this region. Moreover, there is not enough information on temporal patterns of spring discharge in the area. In this context, it is essential to accurately predict spring discharge, as well as understand karst hydrological processes in a thorough manner, so that water shortages in this area could be predicted and managed efficiently. The objectives of this study were to determine the primary factors that govern spring discharge patterns and to develop a state-space model to predict spring discharge. Spring discharge, precipitation (PT), relative humidity (RD), water temperature (WD), and electrical conductivity (EC) were the variables analyzed in the present work, and they were monitored at two different locations (referred to as karst springs A and B, respectively, in this paper) in a karst catchment area in southwest China from May to November 2015. Results showed that a state-space model using any combinations of variables outperformed a classical linear regression, a back-propagation artificial neural network model, and a least square support vector machine in modeling spring discharge time series for karst spring A. The best state-space model was obtained by using PT and RD, which accounted for 99.9% of the total variation in spring discharge. This model was then applied to an independent data set obtained from karst spring B, and it provided accurate spring discharge estimates. Therefore, state-space modeling was a useful tool for predicting spring discharge in karst regions in southwest China, and this modeling procedure may help researchers to obtain accurate results in other karst regions.

Health and safety in clinical laboratories is becoming an increasingly important subject as a result of emergence of highly infectious diseases such as Hepatitis and HIV. A cross sectional study was carried out to study the safety measures being adopted in clinical laboratories of India. Heads of laboratories of teaching hospitals of India were subjected to a standardized, pretested questionnaire. Response rate was 44.8%. only 60% of laboratories had person in-charge of safety in laboratory. Seventy three percent of laboratories had safety education program regarding hazards. In 91% of laboratories staff is using protective clothing while working in laboratories. Hazardous material regulations are followed in 78% of laboratories. Regular health check ups are carried among laboratory staff in 43.4% of laboratories.Safety manual is available in 56.5% of laboratories. 73.9% of laboratories are equipped with fire extinguishers. Fume cupboards are provided in 34.7% of laboratories and they are regularly checked in 87.5% of these laboratories. In 78.26% of laboratories suitable measures are taken to minimize formation of aerosols.In 95.6% of laboratories waste is disposed off as per bio-medical waste management handling rules. Laboratory of one private medical college was accredited with NABL and safety parameters were better in that laboratory. Installing safety engineered devices apparently contributes to significant decrease in injuries in laboratories; laboratory safety has to be a part of overall quality assurance programme in hospitals. Accreditation has to be made necessary for all laboratories.

National Renewable Energy Laboratory program on lightning risk and wind turbine generator protection

Energy Technology Data Exchange (ETDEWEB)

Muljadi, E. [National Renewable Energy Lab., Golden, CO (United States); McNiff, B. [McNiff Light Industry, Blue Hill, ME (United States)

1997-12-31

In the early development of wind turbine generators (WTG) in the United States, wind farms were primarily located in California where lightning activity is the lowest in the United States. As such, lightning protection for wind turbines was not considered to be a major issue for designers or wind farm operators. However, wind turbine installations are expanding into the Midwest, Southwest and other regions of the United States where lightning activity is significantly more intense and lightning damage to wind turbines is more common. There is a growing need, therefore, to better understand lightning activity on wind farms and to improve wind turbine lightning protection systems. In support of the U.S. Department of Energy/Electric Power Research Institute (DOE/EPRI) Utility Wind Turbine Verification Program (TVP), the National Renewable Energy Laboratory (NREL) has recently begun to take steps to determine the extent of damage due to lightning and the effectiveness of various lightning protection techniques for wind power plants. Working through the TVP program, NREL will also perform outreach and education to (1) help manufacturers to provide equipment that is adequately designed to survive lightning, (2) make sure that operators are aware of effective safety procedures, and (3) help site designers and wind farm developers take the risk of lightning into account as effectively as possible.

A retrospective, controlled, interrupted time series (ITS) study. University of Utah Health Care, a 500-bed academic medical center in Salt Lake City, Utah. All patients 18 years or older admitted to the hospital to a service other than obstetrics, rehabilitation, or psychiatry. Multifaceted quality-improvement initiative in a hospitalist service including education, process change, cost feedback, and financial incentive. Primary outcomes of lab cost per day and per visit. Secondary outcomes of number of basic metabolic panel (BMP), comprehensive metabolic panel (CMP), complete blood count (CBC), and prothrombin time/international normalized ratio tests per day; length of stay (LOS); and 30-day readmissions. A total of 6310 hospitalist patient visits (intervention group) were compared to 25,586 nonhospitalist visits (control group). Among the intervention group, the unadjusted mean cost per day was reduced from $138 before the intervention to $123 after the intervention (P analysis showed significant reductions in cost per day, cost per visit, and the number of BMP, CMP, and CBC tests per day (P = 0.034, 0.02, <0.001, 0.004, and <0.001). LOS was unchanged and 30-day readmissions decreased in the intervention group. A multifaceted approach to laboratory reduction demonstrated a significant reduction in laboratory cost per day and per visit, as well as common tests per day at a major academic medical center.

Sociology of scientific knowledge and science education part 2: Laboratory life under the microscope

Slezak, Peter

1994-10-01

This article is the second of two that examine some of the claims of contemporary sociology of scientific knowledge (SSK) and the bearing of these claims upon the rationale and practice of science teaching. In the present article the celebrated work Laboratory Life of Latour and Woolgar is critically examined. Its radical, iconoclastic view of science is shown to be not merely without foundation but an extravagant deconstructionist nihilism according to which all science is fiction and the world is said to be socially constructed by negotiation. On this view, the success of a theory is not due to its intellectual merits or explanatory plausibility but to the capacity of its proponents to “extract compliance” from others. If warranted, such views pose a revolutionary challenge to the entire Western tradition of science and the goals of science education which must be misguided and unrealizable in principle. Fortunately, there is little reason to take these views seriously, though their widespread popularity is cause for concern among science educators.

Is the negative IOD during 2016 the reason for monsoon failure over southwest peninsular India?

Science.gov (United States)

Sreelekha, P. N.; Babu, C. A.

2018-01-01

The study investigates the mechanism responsible for the deficit rainfall over southwest peninsular India during the 2016 monsoon season. Analysis shows that the large-scale variation in circulation pattern due to the strong, negative Indian Ocean Dipole phenomenon was the reason for the deficit rainfall. Significant reduction in the number of northward-propagating monsoon-organized convections together with fast propagation over the southwest peninsular India resulted in reduction in rainfall. On the other hand, their persistence for longer time over the central part of India resulted in normal rainfall. It was found that the strong convection over the eastern equatorial Indian Ocean creates strong convergence over that region. The combined effect of the sinking due to the well-developed Walker circulation originated over the eastern equatorial Indian Ocean and the descending limb of the monsoon Hadley cell caused strong subsidence over the western equatorial Indian Ocean. The tail of this large-scale sinking extended up to the southern parts of India. This hinders formation of monsoon-organized convections leading to a large deficiency of rainfall during monsoon 2016 over the southwest peninsular India.

The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations.

The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory equipment to outside universities, industrial researchers, and elementary and secondary education programs. In the past, the ORNL Robotics and Process Systems Division (RPSD) has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics, but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations

Immunohistochemistry (IHC) is important for cytology but poses special challenges because preanalytic conditions may differ from the conditions of IHC-positive controls. To broadly survey cytology laboratories to quantify preanalytic platforms for cytology IHC and identify problems with particular platforms or antigens. To discover how validation guidelines for HER2 testing have affected cytology. A voluntary survey of cytology IHC practices was sent to 1899 cytology laboratories participating in the College of American Pathologists Nongynecologic Cytopathology Education Program in the fall of 2009. A total of 818 laboratories (43%) responded to the survey by April 2010. Three hundred fourty-five of 791 respondents (44%) performed IHC on cytology specimens. Seventeen different fixation and processing platforms prior to antibody reaction were reported. A total of 59.2% of laboratories reported differences between the platforms for cytology specimens and positive controls, but most (155 of 184; 84%) did not alter antibody dilutions or antigen retrieval for cytology IHC. When asked to name 2 antibodies for which staining conditions differed between cytology and surgical samples, there were 18 responses listing 14 antibodies. A total of 30.6% of laboratories performing IHC offered HER2 testing before publication of the 2007 College of American Pathologists/American Society of Clinical Oncologists guidelines, compared with 33.6% afterward, with increased performance of testing by reference laboratories. Three laboratories validated a nonformalin HER2 platform. The platforms for cytology IHC and positive controls differ for most laboratories, yet conditions are uncommonly adjusted for cytology specimens. Except for the unsuitability of air-dried smears for HER2 testing, the survey did not reveal evidence of systematic problems with any antibody or platform.

Coastal upwelling along the southwest coast of India – ENSO modulation

2008-06-01

Full Text Available An index of El Niño Southern Oscillation (ENSO in the Pacific during pre monsoon season is shown to account for a significant part of the variability of coastal Sea Surface Temperature (SST anomalies measured a few months later within the wind driven southwest coast of India coastal upwelling region 7° N–14° N. This teleconnection is thought to result from an atmospheric bridge between the Pacific and north Indian Oceans, leading to warm (cold ENSO events being associated with relaxation (intensification of the Indian trade winds and of the wind-induced coastal upwelling. This ENSO related modulation of the wind-driven coastal upwelling appears to contribute to the connection observed at the basin-scale between ENSO and SST in the Arabian Sea. The ability to use this teleconnection to give warning of large changes in the southwest coast of India coastal upwelling few months in advance is successfully tested using data from 1998 and 1999 ENSO events.

Kudo, Yoshiko; Osawa, Susumu

2015-10-01

The strategy of international cooperation in the clinical laboratory field was analyzed to improve the quality of intervention by reviewing documents from international organizations and the Japanese government. Based on the world development agenda, the target of action for health has shifted from communicable diseases to non-communicable diseases (NCD). This emphasizes the importance of comprehensive clinical laboratories instead of disease-specific examinations in developing countries. To achieve this goal, the World Health Organization (WHO) has disseminated to the African and Asian regions the Laboratory Quality Management System (LQMS), which is based on the same principles of the International Organization of Standardization (ISO) 15189. To execute this strategy, international experts must have competence in project management, analyze information regarding the target country, and develop a strategy for management of the LQMS with an understanding of the technical aspects of laboratory work. However, there is no appropriate pre- and post-educational system of international health for Japanese international workers. Universities and academic organizations should cooperate with the government to establish a system of education for international workers. Objectives of this education system must include: (1) training for the organization and understanding of global health issues, (2) education of the principles regarding comprehensive management of clinical laboratories, and (3) understanding the LQMS which was employed based on WHO's initiative. Achievement of these objectives will help improve the quality of international cooperation in the clinical laboratory field.

Detection of acid-fast bacilli in respiratory specimens serves as an initial pulmonary tuberculosis (TB) diagnosis. Laboratories are the essential and fundamental part of all health systems. This study aimed to describe how laboratory technicians perceived their own self and work. This included perceived self-efficacy, perceived role, perceived equipment availability, perceived procedures, perceived reward and job, and perceived benefit of health education, as well as level of knowledge and attitudes related to work performance of laboratory technicians. This was a cross-sectional quantitative study involving 120 laboratory technicians conducted in Central Java. Interviews and observation were conducted to measure performance and work-related variables. Among 120 laboratory technicians, 43.3% showed fairly good performance. They complied with 50%-75% of all procedures, including sputum collection, laboratory tools utilization, sputum smearing, staining, smear examination, grading of results, and universal precaution practice. Perceived role, perceived self-efficacy, and knowledge of laboratory procedures were significantly correlated to performance, besides education and years of working as a laboratory technician. Perceived equipment availability was also significantly correlated to performance after the education variable was controlled. Most of the laboratory technicians believed that they have an important role in TB patients' treatment and should display proper self-efficacy in performing laboratory activities. The result may serve as a basic consideration to develop a policy for enhancing motivation of laboratory technicians in order to improve the TB control program.

Geochemical monitoring of groundwater in seismically-active regions has been carried out since 1970s. Precursors were well documented, but often criticized for anecdotal or fragmentary signals, and for lacking a clear physico-chemical explanation for these anomalies. Here we report - as potential seismic precursor - oxygen isotopic ratio anomalies of +0.24‰ relative to the local background measured in groundwater, a few months before the Tottori earthquake (M 6.6) in Southwest Japan. Samples were deep groundwater located 5 km west of the epicenter, packed in bottles and distributed as drinking water between September 2015 and July 2017, a time frame which covers the pre- and post-event. Small but substantial increase of 0.07‰ was observed soon after the earthquake. Laboratory crushing experiments of aquifer rock aimed to simulating rock deformation under strain and tensile stresses were carried out. Measured helium degassing from the rock and 18 O-shift suggest that the co-seismic oxygen anomalies are directly related to volumetric strain changes. The findings provide a plausible physico-chemical basis to explain geochemical anomalies in water and may be useful in future earthquake prediction research.

This study assessed the effects of a continued education program on the agreement between cervical cytopathology exams interpreted by local laboratories and interpretation made by an external quality control laboratory (LabMEQ). Overall, 9,798 exams were analyzed between 2007 and 2008, prior to implementation of a continued education program, and 10,028 between 2010 and 2011, following implementation. Continued education consisted of theoretical and practical classes held every two months. The chi-square test and the kappa coefficient were used in the statistical analysis. Following implementation of continued education, the rate of false-negative results, and those leading to delays in clinical management fell in eight laboratories and the rate of false-positive results in five. Agreement between the results reported by the laboratories and the findings of LabMEQ, evaluated according to clinical management, remained excellent in three laboratories (kappa >0.80 and 0.60 and clinical management. © 2016 Wiley Periodicals, Inc.

The Laboratory Earth professional development series, which has been funded by NASA, consists of three, three- credit hour, graduate level, distance-delivered, online courses designed for K- 8 (and above) educators. Currently, we have delivered two module-based courses, Laboratory Earth I: Earth and its Systems and Laboratory Earth II: Earth's Natural Resource Systems. A third course tentatively titled, Laboratory Earth: Earth's Changing Environments, is under development. Our objectives are to deliver a high quality professional development experience, improve participant's ability to understand and apply Earth system science concepts in their classroom, and to increase teacher's sense of belonging to a community. Each course consists of four modules that engage students using multiple strategies to meet a variety of learning styles. To document learning, content questions are used to focus the student on the concepts they will be learning throughout the course. These questions are also used to assess the progress the student has made toward learning the concepts from the beginning to the end of the course. Analysis of the responses to the content questions from Lab Earth I demonstrates significant knowledge gains from the beginning to the end of the course. Preliminary data also suggests that the extent of learning is higher in the 8-week version than it is in the 16-week version of the course. An implicit goal of the courses is to help participants focus on learning, not grades. Unfortunately, grades have to be issued. Our grading strategy has evolved to a system that uses the ability of students to master course content along with active participation and the on-time, quality completion of the grading elements in the course. Course content mastery can be demonstrated in a variety of ways and it is up to the student to choose the method that they would like to use. Methods include writing essays, creating presentations, preparing an oral journal, and developing

Remote Laboratory Java Server Based on JACOB Project

Directory of Open Access Journals (Sweden)

Pavol Bisták

2011-02-01

Full Text Available Remote laboratories play an important role in the educational process of engineers. This paper deals with the structure of remote laboratories. The principle of the proposed remote laboratory structure is based on the Java server application that communicates with Matlab through the COM technology for the data exchange under the Windows operating system. Java does not support COM directly so the results of the JACOB project are used and modified to cope with this problem. In laboratories for control engineering education a control algorithm usually runs on a PC with Matlab that really controls the real plant. This is the server side described in the paper in details. To demonstrate the possibilities of a remote control a Java client server application is also introduced. It covers communication and offers a user friendly interface for the control of a remote plant and visualization of measured data.

Professor Created On-line Biology Laboratory Course

Science.gov (United States)

Bowman, Arthur W.

2010-01-01

This paper will share the creation, implementation, and modification of an online college level general biology laboratory course offered for non-science majors as a part of a General Education Curriculum. The ability of professors to develop quality online laboratories will address a growing need in Higher Education as more institutions combine course sections and look for suitable alternative course delivery formats due to declining departmental budgets requiring reductions in staffing, equipment, and supplies. Also, there is an equal or greater need for more professors to develop the ability to create online laboratory experiences because many of the currently available online laboratory course packages from publishers do not always adequately parallel on-campus laboratory courses, or are not as aligned with the companion lecture sections. From a variety of scientific simulation and animation web sites, professors can easily identify material that closely fit the specific needs of their courses, instructional environment, and students that they serve. All too often, on-campus laboratory courses in the sciences provide what are termed confirmation experiences that do NOT allow students to experience science as would be carried out by scientists. Creatively developed online laboratory experiences can often provide the type of authentic investigative experiences that are not possible on-campus due to the time constraints of a typical two-hour, once-per-week-meeting laboratory course. In addition, online laboratory courses can address issues related to the need for students to more easily complete missing laboratory assignments, and to have opportunities to extend introductory exercises into more advanced undertakings where a greater sense of scientific discovery can be experienced. Professors are strongly encourages to begin creating online laboratory exercises for their courses, and to consider issues regarding assessment, copyrights, and Intellectual Property

DeBoy, John M; Boulton, Matthew L; Carpenter, David F

2013-01-01

The public health, environmental, and agricultural laboratory (PHEAL) workforce is a key component of the public health infrastructure. The national laboratory workforce faces an ongoing challenge of recruitment and retention of workers often related to pay and other compensation issues. To collect information on laboratory salaries and laboratory compensation practices using a national compensation survey targeting the PHEAL workforce. Seventy-three of 109 (67%) PHEAL directors in the 50 states and District of Columbia collectively employ 3723/4830 (77%) PHEAL employees in the United States. A standardized survey was developed and administered in 2010. Compensation data were compiled by job classification, geographic region, laboratory gross operating budget size, laboratory staff size, and laboratory type. Laboratory staff size ranged from 3 to 327 individuals (mean = 74 and median = 51). Median base salaries were lowest in the Southwest and South and highest in the Mountain and Pacific regions. Mean and median laboratory gross operating budgets for all participating PHEALs were $8 609 238 and $5 671 500, respectively. Extra cash compensation, used by 8 of 60 (13.3%) PHEALs, was more likely to go to a scientist-manager or scientist-supervisor. In 2010, a standardized national compensation survey of technical and scientific public health employees working in 73 PHEALs was effective in collecting previously unavailable data about laboratory salaries, laboratory budgets, and payroll practices. Laboratory salaries varied by geographic region and there was an uneven distribution of extra cash compensation among job classifications. The compensation data collected may be useful in characterizing and improving laboratory salary structures and practices to better support workforce recruitment and retention.

Objective: To evaluate the perceptions of medical students regarding their training utilizing facilities provided in the skill laboratory of a public sector medical college. Study Design: Cross-sectional study. Place and Duration of Study: Army Medical College, Rawalpindi, from October to December 2014. Methodology: Students of final year MBBS who had underwent skill laboratory training were recruited through convenience purposive sampling. Students not exposed to skill laboratory training were excluded. Data collection tool was a questionnaire having 23 questions with responses on Likert Scale as strongly disagree, disagree, agree and strongly agree coded as 1, 2, 3 and 4, respectively. Data was analysed on SPSS version 22. Results: There were 78 (57 percent) male and 59 (43 percent) female students out of 137, with mean age of 22.59 ± 0.74 years. The response rate was 68.5 percent. Cronbach's Alpha test was 0.84 showing high reliability. The mean of sum of all the 23 items was 63.85 ± 8.71, whereas item means was 2.78 ± 0.38, reflecting a high inclination of students towards skill laboratory training. Frequency of students responding in favour of skill laboratory training was significantly high (p < 0.05). Conclusion: Medical students perceived skill laboratory training as a favoured learning strategy as compared to practising on real patients for acquisition of various aspects of clinical skills, knowledge and attitude.

Updating the immunology curriculum in clinical laboratory science.

Science.gov (United States)

Stevens, C D

2000-01-01

To determine essential content areas of immunology/serology courses at the clinical laboratory technician (CLT) and clinical laboratory scientist (CLS) levels. A questionnaire was designed which listed all major topics in immunology and serology. Participants were asked to place a check beside each topic covered. For an additional list of serological and immunological laboratory testing, participants were asked to indicate if each test was performed in either the didactic or clinical setting, or not performed at all. A national survey of 593 NAACLS approved CLT and CLS programs was conducted by mail under the auspices of ASCLS. Responses were obtained from 158 programs. Respondents from all across the United States included 60 CLT programs, 48 hospital-based CLS programs, 45 university-based CLS programs, and 5 university-based combined CLT and CLS programs. The survey was designed to enumerate major topics included in immunology and serology courses by a majority of participants at two distinct educational levels, CLT and CLS. Laboratory testing routinely performed in student laboratories as well as in the clinical setting was also determined for these two levels of practitioners. Certain key topics were common to most immunology and serology courses. There were some notable differences in the depth of courses at the CLT and CLS levels. Laboratory testing associated with these courses also differed at the two levels. Testing requiring more detailed interpretation, such as antinuclear antibody patterns (ANAs), was mainly performed by CLS students only. There are certain key topics as well as specific laboratory tests that should be included in immunology/serology courses at each of the two different educational levels to best prepare students for the workplace. Educators can use this information as a guide to plan a curriculum for such courses.

Student Teachers' Modeling of Acceleration Using a Video-Based Laboratory in Physics Education: A Multimodal Case Study

Directory of Open Access Journals (Sweden)

Louis Trudel

2016-06-01

Full Text Available This exploratory study intends to model kinematics learning of a pair of student teachers when exposed to prescribed teaching strategies in a video-based laboratory. Two student teachers were chosen from the Francophone B.Ed. program of the Faculty of Education of a Canadian university. The study method consisted of having the participants interact with a video-based laboratory to complete two activities for learning properties of acceleration in rectilinear motion. Time limits were placed on the learning activities during which the researcher collected detailed multimodal information from the student teachers' answers to questions, the graphs they produced from experimental data, and the videos taken during the learning sessions. As a result, we describe the learning approach each one followed, the evidence of conceptual change and the difficulties they face in tackling various aspects of the accelerated motion. We then specify advantages and limits of our research and propose recommendations for further study.

Jovičić, Snežana; Majkić-Singh, Nada

2017-04-01

Medical biochemistry is the usual name for clinical biochemistry or clinical chemistry in Serbia, and medical biochemist is the official name for the clinical chemist (or clinical biochemist). This is the largest sub-discipline of the laboratory medicine in Serbia. It includes all aspects of clinical chemistry, and also laboratory hematology with coagulation, immunology, etc. Medical biochemistry laboratories in Serbia and medical biochemists as a profession are part of Health Care System and their activities are regulated through: the Health Care Law and rules issued by the Chamber of Medical Biochemists of Serbia. The first continuous and organized education for Medical Biochemists (Clinical Chemists) in Serbia dates from 1945, when the Department of Medical Biochemistry was established at the Pharmaceutical Faculty in Belgrade. In 1987 at the same Faculty a five years undergraduate study program was established, educating Medical Biochemists under a special program. Since the academic year 2006/2007 the new five year undergraduate (according to Bologna Declaration) and four-year postgraduate program according to EC4 European Syllabus for Postgraduate Training in Clinical Chemistry and Laboratory Medicine has been established. The Ministry of Education and Ministry of Public Health accredited these programs. There are four requirements for practicing medical biochemistry in the Health Care System: University Diploma of the Faculty of Pharmacy (Study of Medical Biochemistry), successful completion of the professional exam at the Ministry of Health after completion of one additional year of obligatory practical training in the medical biochemistry laboratories, membership in the Serbian Chamber of Medical Biochemists and licence for skilled work issued by the Serbian Chamber of Medical Biochemists. In order to present laboratory medical biochemistry practice in Serbia this paper will be focused on the following: Serbian national legislation, healthcare services

Southwest Memphis is a residential region surrounded by fossil fuel burning, steel, refining, and food processing industries, and considerable mobile sources whose emissions may pose adverse health risks to local residents. This study characterizes cancer and non-cancer risks resulting from exposure to ambient air toxics in southwest Memphis. Air toxics samples were collected at a central location every 6 days from June 5, 2008 to January 8, 2010. Volatile organic compounds (VOCs) were collected in evacuated stainless-steel canisters and aldehydes by DNPH cartridges, and samples were analyzed for 73 target compounds. A total of 60 compounds were detected and 39 were found in over 86% of the samples. Mean concentrations of many compounds were higher than those measured in many industrial communities throughout the U.S. The cumulative cancer risk associated with exposure to 13 carcinogens found in southwest Memphis air was 2.3 × 10-4, four times higher than the national average of 5.0 × 10-5. Three risk drivers were identified: benzene, formaldehyde, and acrylonitrile, which contributed 43%, 19%, and 14% to the cumulative risk, respectively. This is the first field study to confirm acrylonitrile as a potential risk driver. Mobile, secondary, industrial, and background sources contributed 57%, 24%, 14%, and 5% of the risk, respectively. The results of this study indicate that southwest Memphis, a region of significant income, racial, and social disparities, is also a region under significant environmental stress compared with surrounding areas and communities.

Numerical Study of a Southwest Vortex Rainstorm Process Influenced by the Eastward Movement of Tibetan Plateau Vortex

Directory of Open Access Journals (Sweden)

Xiaoli Liu

2018-01-01

Full Text Available A number of studies revealed the possible eastward movement of the Tibetan Plateau low-pressure system in summer and indicated the enhancement effect of this process on the southwest vortex in the Sichuan Basin, which can induce strong convective precipitation and flood events in China. In this study, a numerical simulation of a southwest vortex rainstorm process was performed. The results show that the low-pressure system originated from the Tibetan Plateau affects the southwest vortex mainly at the middle level, causing the strength increase of southwest vortex (SWV, and acts as a connection between the positive vorticity centers at the upper and lower layers. For the microscopic cloud structure, the vertical updraft of the cloud cluster embedded in the SWV increases as the low-pressure system from the plateau arrives at the Sichuan Basin. Vapor and liquid cloud water at the lower level are transported upward, based on which the ice cloud at the upper level and the warm cloud at the lower level are joined to create favorable conditions for the growth of ice crystals. As the ice crystals grow up, snow and graupel particles form, which substantially elevates the precipitation. This effect leads to the rapid development of SWV rainstorm clouds and the occurrence of precipitation. In addition to the effect of the plateau vortex, the subsequent merging of the convective clouds is another important factor for heavy rainfall because it also leads to development of convective clouds, causing heavy rainfall.

Introduction : A large proportion of the Ethiopian population (approximately 68%) lives in malaria risk areas. Millions of long-lasting insecticide treated nets (LLINs) have been distributed as part of the malaria prevention and control strategy in the country. This study assessed the ownership, access and use of LLNs in the malaria endemic southwest Ethiopia. Methods: A community-based cross-sectional study was conducted in southwest Ethiopia during October-November 2015, including 836 households from sixteen villages around Gilgel-Gibe dam area. Indicators of ownership, access and use of LLINs were derived following the Roll Back Malaria (RBM) guidelines. Factors associated with failure for both LLIN access and use were analysed at household level using a multivariate logistic regression model. Results: The proportion of households with at least one LLIN was 82.7% (95% CI: 80.0, 85.1). However, only 68.9% (95% CI: 65.6, 71.9) had enough LLINs to cover all family members (with ≥one LLIN for every two persons). While 75.3% (95% CI: 68.4, 83.0) of the population was estimated to have accessed to LLINs, only 63.8% (95% CI: 62.3, 65.2) reported to have used a LLIN the previous night. The intra-household gap (i.e., households owning at least one LLIN, but unable to cover all family members) and the behavioral gap (i.e., household members who did not sleep under a LLIN despite having access to one) were 16.8% and 10.5%, respectively. Age, marital status and education of household heads, as well as household size and cooking using firewood were associated with the access to enough LLINs within households. Decreased access to LLINs at households was the main determinant for not achieving ≥80% household members sleeping under a LLIN the previous night. Other associated factors were household size and education level of household head. Conclusions: LLIN coverage levels in study villages remain below national targets of 100% for ownership and 80% for use. The access to

Atmospheric forcing on the seasonal variability of sea level at Cochin, southwest coast of India

Srinivas, K.; Dinesh Kumar, P. K.

2006-07-01

The seasonal cycles of some atmospheric parameters at Cochin (southwest coast of India) have been studied with a specific emphasis on the role played by them in forcing the seasonal sea level. Equatorward along-shore wind stress as well as equatorward volume transport by coastal currents along the Indian peninsula could play an important role in the sea level low during the premonsoon and southwest monsoon seasons. During postmonsoon season, along-shore wind stress plays no major role in the high sea level whereas this could be due to the poleward volume transport by the coastal along-shore currents. Atmospheric pressure and river discharge do not seem to influence much the sea level during the southwest monsoon period, even though the river discharge during that period is considerable. The sea level was minimal during the southwest monsoon season, when the river discharge was at its annual maximum. The difference between the seasonal march of observed and pressure corrected sea level (CSL) was not significant for the study region. Harmonic analysis of the climatological data on the various parameters revealed that air temperature is the only parameter with a dominance of the semi-annual over the annual cycle. Cross-shore wind stress indicated strong interannual variability whereas relative density showed strong seasonal variability. The climatological seasonal cycles of CSL at eight other tide gauge stations along the west coast of the Indian subcontinent are also examined, to assess the role of various forcings on the seasonal sea level cycle. The signatures of El Nino-Southern Oscillation (ENSO) phenomenon could be seen in some of the parameters (SST, air temperature, atmospheric pressure, along-shore wind stress, relative density and sea level). The signature of ENSO was particularly strong in the case of atmospheric pressure followed by relative density, the variance accounted by the relationship being 47% and 16%, respectively.

The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations

The current study was designed to explore the epidemiology of extremities chronic osteomyelitis, its prognosis and the complications of the treatment methods being used in southwest China. The data from osteomyelitis patients treated at the Department of Orthopaedics, Southwest Hospital, China between May 2011 and September 2016 were collected and analysed. The study comprised 503 admitted patients, of which 416 males and 87 were females, with an average age of 40.15 ± 5.64 years. Approximately 356 cases were followed for more than 18 months; the average bone union time was 6.24 ± 0.76 months in 94.1% (335) patients, and infections were almost controlled in 93.8% patients. The rate of infection control with the induced membrane technique was higher than with the I-stage free bone graft. Iliac infection was the main complication of the induced membrane technique, and impaired joint activity was the main complication of I-stage free bone grafts. In southwest China, the incidence of haematogenous osteomyelitis, caused mainly by Staphylococcus aureus, remains very high. The speed of bone defect repair and the rate of infection control with the induced membrane technique were superior to those of I-stage free bone grafts. Internal fixation should be given priority because it offers reduced complications with no increase in the recurrence of infection.

This study aimed to compare the perception of the academic learning environment between medical laboratory science students and nursing students at Saint Louis University, Baguio City, Philippines. A cross-sectional survey research design was used to measure the perceptions of the participants. A total of 341 students from the Department of Medical Laboratory Science, School of Natural Sciences, and the School of Nursing answered the Dundee Ready Education Environment Measure (DREEM) instrument from April to May 2016. Responses were compared according to course of study, gender, and year level. The total mean DREEM scores of the medical laboratory science students and nursing students did not differ significantly when grouped according to course of study, gender, or year level. Medical laboratory science students had significantly lower mean scores in the sub-domains 'perception of learning' and 'perception of teaching.' Male medical laboratory science students had significantly lower mean scores in the sub-domain 'perception of learning' among second year students. Medical laboratory science students had significantly lower mean scores in the sub-domain 'perception of learning.' Nursing students identified 7 problem areas, most of which were related to their instructors. Medical laboratory science and nursing students viewed their academic learning environment as 'more positive than negative.' However, the relationship of the nursing instructors to their students needs improvement.

The estimates of existing, incremental, and the undeveloped hydropower potential for all states in the various regions of the country are presented. In the Pacific Southwest region, the maximum physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy greater than 85,000 GWH. By comparison, these values represent about 6% of the total potential capacity and hydroelectric energy generation estimated for the entire US. Of the total capacity estimated for the region, 9900 MW has been installed. The remainder (23,200 MW) is the maximum which could be developed by upgrading and expanding existing projects (6000 MW) and by installing new hydroelectric power capacity at all potentially feasible, undeveloped sites (17,200 MW). Small-scale facilities account for less than 4% of the region's total installed capacity, but another 600 MW could be added to these and other small water resource projects. In addition, 600 MW could be installed at potentially feasible, undeveloped small-scale sites. The small-scale resource varies considerably, with the states of California and Utah having the largest potential for incremental development at existing projects in the Pacific Southwest region. States comprising the Southwest are Arizona, California, Hawaii, Nevada, and Utah.

Science.gov (United States)

Lacy, Sarah Louise Trotman

Since laboratory-based science courses have become an essential element of any science curriculum and are required by the Mississippi Department of Education for graduation, the chemistry laboratories in the public high schools in Mississippi must be safe. The purpose of this study was to determine: the safety characteristics of a high school chemistry laboratory; the perceived safety characteristics of the chemistry laboratories in public high schools in Mississippi; the basic safety knowledge of chemistry teachers in public high schools in Mississippi, where chemistry teachers in Mississippi gain knowledge about laboratory safety and instruction; if public high school chemistry laboratories in Mississippi adhere to recommended class size, laboratory floor space per student, safety education, safety equipment, and chemical storage; and the relationship between teacher knowledge of chemistry laboratory safety and the safety status of the laboratory in which they teach. The survey instrument was composed of three parts. Part I Teacher Knowledge consisted of 23 questions concerning high school chemistry laboratory safety. Part II Chemistry Laboratory Safety Information consisted of 40 items divided into four areas of interest concerning safety in high school chemistry laboratories. Part III Demographics consisted of 11 questions relating to teacher certification, experience, education, and safety training. The survey was mailed to a designated chemistry teacher in every public high school in Mississippi. The responses to Part I of the survey indicated that the majority of the teachers have a good understanding of knowledge about chemistry laboratory safety but need more instruction on the requirements for a safe high school chemistry laboratory. Less than 50% of the responding teachers thought they had received adequate preparation from their college classes to conduct a safe chemistry laboratory. According to the responses of the teachers, most of their high school

Electrical and computer engineering graduates need practical working skills with real-world electronic devices, which are addressed to some extent by hands-on laboratories. Deployment capacity of hands-on laboratories is typically constrained due to insufficient equipment availability, facility shortages, and lack of human resources for in-class support and maintenance. At the same time, at many sites, existing experimental systems are usually underutilized due to class scheduling bottlenecks. Nowadays, online education gains popularity and remote laboratories have been suggested to broaden access to experimentation resources. Remote laboratories resolve many problems as various costs can be shared, and student access to instrumentation is facilitated in terms of access time and locations. Labs are converted to homeworks that can be done without physical presence in laboratories. Even though they are not providing full sense of hands-on experimentation, remote labs are a viable alternatives for underserved educational sites. This paper studies remote modality of USRP-based radio-communication labs offered by National Instruments (NI). The labs are offered to graduate and undergraduate students and tentative assessments support feasibility of remote deployments.

Achakulwisut, P.; Mickley, L. J.; Anenberg, S. C.

2018-05-01

We investigate the present-day sensitivity of fine dust levels in the US Southwest to regional drought conditions and use the observed relationships to assess future changes in fine dust levels and associated health impacts under climate change. Empirical Orthogonal Function analysis reveals that the most dominant mode of fine dust interannual variability for each season consists of a pattern of large-scale co-variability across the Southwest. This mode is strongly correlated to the Standardized Precipitation-Evapotranspiration Index (SPEI) accumulated over 1–6 months in local and surrounding regions spanning the major North American deserts. Across the seasons, a unit decrease in the 2 month SPEI averaged over the US Southwest and northern Mexico is significantly associated with increases in Southwest fine dust of 0.22–0.43 μg m‑3. We apply these sensitivities to statistically downscaled meteorological output from 22 climate models following two Representative Concentration Pathways (RCPs), and project future increases in seasonal mean fine dust of 0.04–0.10 μg m‑3 (5%–8%) under RCP2.6 and 0.15–0.55 μg m‑3 (26%–46%) under RCP8.5 relative to the present-day (2076–2095 vs. 1996–2015). Combined with the same projections of future population and baseline incidence rates, annual premature mortality attributable to fine dust exposure could increase by 140 (24%) deaths under RCP2.6 and 750 (130%) deaths under RCP8.5 for adults aged ≥30 years, and annual hospitalizations due to cardiovascular and respiratory illnesses could increase by 170 (59%) admissions under RCP2.6 and 860 (300%) admissions under RCP8.5 for adults aged ≥65 years in the Southwest relative to the present-day. Our results highlight a climate penalty that has important socioeconomic and policy implications for the US Southwest but is not yet widely recognized.

We investigated the status of caregiver burden and identified the factors related to caregiver burden among family caregivers of patients with heart failure in southwest China. A cross-sectional descriptive design with a convenience sample was adopted. Patient and family caregiver dyads (n = 226) in four hospitals in Chengdu, China were recruited from June 2013 to July 2014. The instruments used in this study included the Social Support Rating Scale, the Zarit Burden Interview, and the General Self-Efficacy Scale. Multivariate analysis was used to identify the factors associated with caregiver burden. Forty-four percent of the variance of the caregiver burden was explained by the payment type for treatment, monthly family income, relationship to the patient, caregivers' self-efficacy, and social support. The caregiver burden in southwest China was higher than studies conducted in developed areas. Specific to southwest China, the financial burden and insufficient resources are the main factors associated with caregiver burden. The results suggest that self-efficacy and social support in underdeveloped areas are potential areas for future intervention. © 2016 John Wiley & Sons Australia, Ltd.

Vision play a vital role in driving where good and efficient visual functioning of the driver is essential. Any significant loss of visual function will diminish a driver's ability to operate a motor vehicle safely and will thus contribute to road traffic injury. However, there is little evidence indicating that defects of vision alone cause road traffic accidents. To determine the impact of visual impairment and other factors on road traffic accident among vehicle drivers. A cross-sectional descriptive study was conducted on 249 sampled drivers in Southwest Ethiopia. A pretested interviewer led questionnaire was used for interview and vision tests were done using Snellen's acuity chart and Ishihara pseudo-isochromatic plates. Statistical analyses were performed using SPSS version 16.0. The mean age of drivers was 33.6 years (SD +/- 10.3). The relative frequency of self reported road traffic accident was 15.3%. The prevalence of uncorrected binocular visual impairment was 1.6% and there was a significant association between visual impairment and road traffic accident (P road traffic accident. There is need for consistent inspection and screening, strict rules and regulations of licensing and health education for drivers to minimize road traffic accident.

J. D. Bess; J. B. Briggs; A. S. Garcia

2011-09-01

One of the challenges in educating our next generation of nuclear safety engineers is the limitation of opportunities to receive significant experience or hands-on training prior to graduation. Such training is generally restricted to on-the-job-training before this new engineering workforce can adequately provide assessment of nuclear systems and establish safety guidelines. Participation in the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) can provide students and young professionals the opportunity to gain experience and enhance critical engineering skills. The ICSBEP and IRPhEP publish annual handbooks that contain evaluations of experiments along with summarized experimental data and peer-reviewed benchmark specifications to support the validation of neutronics codes, nuclear cross-section data, and the validation of reactor designs.

One of the challenges in educating our next generation of nuclear safety engineers is the limitation of opportunities to receive significant experience or hands-on training prior to graduation. Such training is generally restricted to on-the-job-training before this new engineering workforce can adequately provide assessment of nuclear systems and establish safety guidelines. Participation in the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) can provide students and young professionals the opportunity to gain experience and enhance critical engineering skills. The ICSBEP and IRPhEP publish annual handbooks that contain evaluations of experiments along with summarized experimental data and peer-reviewed benchmark specifications to support the validation of neutronics codes, nuclear cross-section data, and the validation of reactor designs.

We used molecular genetic analyses to noninvasively identify individual Amur tigers and define subpopulations of tigers in the Russian Far East. We identified 63 individuals after genotyping 256 feces, 7 hair and 11 blood samples collected within southern, central and northern Sikhote-Alin, as well as Southwest Primorye. Analysis of nuclear DNA at 9 microsatellite loci demonstrated greater genetic similarity between animals from southern and northern Sikhote-Alin (some 500 km apart) than between animals from Ussuriskii State Nature Reserve and Southwest Primorye (less than 10 km apart at their nearest point), suggesting that a true barrier exists preventing movements of tigers between Southwest Primorye and the southern Sikhote-Alin Mountains. © 2015 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

In Hungary, the National Accreditation Body was established by government in 1995 as an independent, non-profit organization, and has exclusive rights to accredit, amongst others, medical laboratories. The National Accreditation Body has two Specialist Advisory Committees in the health care sector. One is the Health Care Specialist Advisory Committee that accredits certifying bodies, which deal with certification of hospitals. The other Specialist Advisory Committee for Medical Laboratories is directly involved in accrediting medical laboratory services of health care institutions. The Specialist Advisory Committee for Medical Laboratories is a multidisciplinary peer review group of experts from all disciplines of in vitro diagnostics, i.e. laboratory medicine, microbiology, histopathology and blood banking. At present, the only published International Standard applicable to laboratories is ISO/IEC 17025:1999. Work has been in progress on the official approval of the new ISO 15189 standard, specific to medical laboratories. Until the official approval of the International Standard ISO 15189, as accreditation standard, the Hungarian National Accreditation Body has decided to progress with accreditation by formulating explanatory notes to the ISO/IEC 17025:1999 document, using ISO/FDIS 15189:2000, the European EC4 criteria and CPA (UK) Ltd accreditation standards as guidelines. This harmonized guideline provides 'explanations' that facilitate the application of ISO/IEC 17025:1999 to medical laboratories, and can be used as a checklist for the verification of compliance during the onsite assessment of the laboratory. The harmonized guideline adapted the process model of ISO 9001:2000 to rearrange the main clauses of ISO/IEC 17025:1999. This rearrangement does not only make the guideline compliant with ISO 9001:2000 but also improves understanding for those working in medical laboratories, and facilitates the training and education of laboratory staff.

Undergraduate Organic Chemistry Laboratory Safety

Science.gov (United States)

Luckenbaugh, Raymond W.

1996-11-01

Each organic chemistry student should become familiar with the educational and governmental laboratory safety requirements. One method for teaching laboratory safety is to assign each student to locate safety resources for a specific class laboratory experiment. The student should obtain toxicity and hazardous information for all chemicals used or produced during the assigned experiment. For example, what is the LD50 or LC50 for each chemical? Are there any specific hazards for these chemicals, carcinogen, mutagen, teratogen, neurotixin, chronic toxin, corrosive, flammable, or explosive agent? The school's "Chemical Hygiene Plan", "Prudent Practices for Handling Hazardous Chemicals in the Laboratory" (National Academy Press), and "Laboratory Standards, Part 1910 - Occupational Safety and Health Standards" (Fed. Register 1/31/90, 55, 3227-3335) should be reviewed for laboratory safety requirements for the assigned experiment. For example, what are the procedures for safe handling of vacuum systems, if a vacuum distillation is used in the assigned experiment? The literature survey must be submitted to the laboratory instructor one week prior to the laboratory session for review and approval. The student should then give a short presentation to the class on the chemicals' toxicity and hazards and describe the safety precautions that must be followed. This procedure gives the student first-hand knowledge on how to find and evaluate information to meet laboartory safety requirements.

Rana, K. P. S.; Kumar, Vineet; Mendiratta, Jatin

2017-11-01

One of the most elementary concepts in freshmen Electrical Engineering subject comprises the Resistance-Inductance-Capacitance (RLC) circuit fundamentals, that is, their time and frequency domain responses. For a beginner, generally, it is difficult to understand and appreciate the step and the frequency responses, particularly the resonance. This paper proposes a student-friendly teaching and learning approach by inculcating the multifaceted versatile software LabVIEWTM along with the educational laboratory virtual instrumentation suite hardware, for studying the RLC circuit time and frequency domain responses. The proposed approach has offered an interactive laboratory experiment where students can model circuits in simulation and hardware circuits on prototype board, and then compare their performances. The theoretical simulations and the obtained experimental data are found to be in very close agreement, thereby enhancing the conviction of students. Finally, the proposed methodology was also subjected to the assessment of learning outcomes based on student feedback, and an average score of 8.05 out of 10 with a standard deviation of 0.471 was received, indicating the overall satisfaction of the students.

Emerging technologies in education and training: applications for the laboratory animal science community.

Science.gov (United States)

Ketelhut, Diane Jass; Niemi, Steven M

2007-01-01

This article examines several new and exciting communication technologies. Many of the technologies were developed by the entertainment industry; however, other industries are adopting and modifying them for their own needs. These new technologies allow people to collaborate across distance and time and to learn in simulated work contexts. The article explores the potential utility of these technologies for advancing laboratory animal care and use through better education and training. Descriptions include emerging technologies such as augmented reality and multi-user virtual environments, which offer new approaches with different capabilities. Augmented reality interfaces, characterized by the use of handheld computers to infuse the virtual world into the real one, result in deeply immersive simulations. In these simulations, users can access virtual resources and communicate with real and virtual participants. Multi-user virtual environments enable multiple participants to simultaneously access computer-based three-dimensional virtual spaces, called "worlds," and to interact with digital tools. They allow for authentic experiences that promote collaboration, mentoring, and communication. Because individuals may learn or train differently, it is advantageous to combine the capabilities of these technologies and applications with more traditional methods to increase the number of students who are served by using current methods alone. The use of these technologies in animal care and use programs can create detailed training and education environments that allow students to learn the procedures more effectively, teachers to assess their progress more objectively, and researchers to gain insights into animal care.

Full Text Available The laboratories like experimental sites are an important tool in education and research, since they allow understanding better the concepts, as well as construct new knowledge. However, there are disadvantages associated with laboratories: the cost of infrastructure, insufficient availability of equipment and the associate risk with the experimentation in harmful environments for human beings. It is considered that these disadvantages can be mitigated with the use of TICs. This paper presents the development of a web platform for remote access to laboratory resources, it is was developed in the Moodle system, and considers laboratories with diverse characteristics. Access to the devices of each laboratory was developed in different web technologies that were later integrated into the platform. The end result was a platform that meets the needs of access to laboratory facilities independent of web technology used and the own characteristics of each laboratory. The results of this study are expected to be are the basis for more flexible and extensive access to resources EAFIT University laboratory and in the future of Colombia.

Agus Ardinansyah

2016-06-01

Full Text Available Nowadays, the clinical skill learning in dental education has begun in pre-clinic, known as Clinical Skill Laboratory (CSL which needs human resources, many and expensive tools and manikins, and enough times for practise. One of the method used in CSL in dental education is PeerAssisted Learning (PAL defined as “the development of knowledge and skill through active help and support among status equals or match companions”. This paper aims is to explain the role of PAL method to improve the effectivity of CSL learning in dental education in preclinical stage. Reviewing on the relevant literatures regarding peer assisted learning on the implementation of the clinical skill laboratory in dental education. The effectivity of CSL learning needs close supervision and individual feedback, so enough tutors is important through the process. This PAL method considered to be helpfull with the increasing numbers of dental students and the limitation of staff faculty. This method is found feasible, well accepted by peer-tutors and students, and can be as effective as conventional learning method. This is also useful for peer-teacher because they more intrinsically motivated, have higher conceptual learning scores, and perceive themselves to be more actively engaged with the environment than students who learn in order to be tested.  However, there are several limitation of this method. The contact time between students and medical doctors may decrease significantlyand it does not seem to be generally qualified to transfer such complex procedures.It also needs peer-teachers training and a detailed manual. Questions concerning the cost-effectiveness and profitability of student tutor-guided technical skills training may thus arise. But one institution that implemented this method states that the majority of their tutors decided to continue their teaching activity in the skills lab and that these experienced tutors, in addition to established faculty staff

Carbon Sequestration Potential in Stands under the Grain for Green Program in Southwest China.

Directory of Open Access Journals (Sweden)

Xiangang Chen

Full Text Available The Grain for Green Program (GGP is the largest afforestation and reforestation project in China in the early part of this century. To assess carbon sequestration in stands under the GGP in Southwest China, the carbon stocks and their annual changes in the GGP stands in the region were estimated based on the following information: (1 collected data on the annually planted area of each tree species under the GGP in Southwest China from 1999 to 2010; (2 development of empirical growth curves and corresponding carbon estimation models for each species growing in the GPP stands; and (3 parameters associated with the stands such as wood density, biomass expansion factor, carbon fraction and the change rate of soil organic carbon content. Two forest management scenarios were examined: scenario A, with no harvesting, and scenario B, with logging at the customary rotation followed by replanting. The results showed that by the years 2020, 2030, 2040, 2050 and 2060, the expected carbon storage of the GGP stands in Southwest China is 139.58 TgC, 177.50-207.55 TgC, 196.86-259.65 TgC, 240.45-290.62 TgC and 203.22-310.03 TgC (T = 1012, respectively. For the same years, the expected annual change in carbon stocks is 7.96 TgCyr-1, -7.95-5.95 TgCyr-1, -0.10-4.67 TgCyr-1, 4.31-2.24 TgCyr-1 and -0.02-1.75 TgCyr-1, respectively. This indicates that the stands significantly contribute to forest carbon sinks in this region. In 2060, the estimated carbon stocks in the seven major species of GGP stands in Southwest China are 4.16-13.01 TgC for Pinus armandii, 6.30-15.01 TgC for Pinus massoniana, 11.51-13.44 TgC for Cryptomeria fortunei, 15.94-24.13 TgC for Cunninghamia lanceolata, 28.05 TgC for Cupressus spp., 5.32-15.63 TgC for Populus deltoides and 5.87-14.09 TgC for Eucalyptus spp. The carbon stocks in these seven species account for 36.8%-41.4% of the total carbon stocks in all GGP stands over the next 50 years.

The role of the teaching laboratory in science education has been debated over the last century. The goals and purposes of the laboratory are still debated and while most science educators consider laboratory a vital part of the education process, they differ widely on the purposes for laboratory and what methods should be used to teach laboratory. One method of instruction, virtual labs, has become popular among some as a possible way of capitalizing on the benefits of lab in a less costly and more time flexible format. The research regarding the use of virtual labs is limited and the few studies that have been done on General Chemistry labs do not use the virtual labs as a substitute for hands-on experiences, but rather as a supplement to a traditional laboratory program. This research seeks to determine the possible viability of a virtual simulation to replace a traditional hands-on electrochemistry lab in the General Chemistry II course sequence. The data indicate that for both content knowledge and the development of hands-on skills the virtual lab showed no significant difference in overall scores on the assessments, but that an individual item related to the physical set-up of a battery showed better scores for the hands-on labs over the virtual labs. Further research should be done to determine if these results are similar in other settings with the use of different virtual labs and how the virtual labs compare to other laboratories using different learning styles and learning goals. One often cited purpose of laboratory experiences in the context of preparing chemists is to simulate the experiences common in chemical research so graduate experience in a research laboratory was a necessary part of my education in the field of laboratory instruction. This research experience provided me the opportunity, to complete an organic synthesis of aurones using a deep eutectic solvent. These solvents show unique properties that make them a viable alternative to ionic

Southwest U.S. Seismo-Acoustic Network: An Autonomous Data Aggregation, Detection, Localization and Ground-Truth Bulletin for the Infrasound Community

Jones, K. R.; Arrowsmith, S.

2013-12-01

The Southwest U.S. Seismo-Acoustic Network (SUSSAN) is a collaborative project designed to produce infrasound event detection bulletins for the infrasound community for research purposes. We are aggregating a large, unique, near real-time data set with available ground truth information from seismo-acoustic arrays across New Mexico, Utah, Nevada, California, Texas and Hawaii. The data are processed in near real-time (~ every 20 minutes) with detections being made on individual arrays and locations determined for networks of arrays. The detection and location data are then combined with any available ground truth information and compiled into a bulletin that will be released to the general public directly and eventually through the IRIS infrasound event bulletin. We use the open source Earthworm seismic data aggregation software to acquire waveform data either directly from the station operator or via the Incorporated Research Institutions for Seismology Data Management Center (IRIS DMC), if available. The data are processed using InfraMonitor, a powerful infrasound event detection and localization software program developed by Stephen Arrowsmith at Los Alamos National Laboratory (LANL). Our goal with this program is to provide the infrasound community with an event database that can be used collaboratively to study various natural and man-made sources. We encourage participation in this program directly or by making infrasound array data available through the IRIS DMC or other means. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

Update of Earthquake Strong-Motion Instrumentation at Lawrence Livermore National Laboratory

Energy Technology Data Exchange (ETDEWEB)

Murray, Robert C. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)

2013-09-01

Following the January 1980 earthquake that was felt at Lawrence Livermore National Laboratory (LLNL), a network of strong-motion accelerographs was installed at LLNL. Prior to the 1980 earthquake, there were no accelerographs installed. The ground motion from the 1980 earthquake was estimated from USGS instruments around the Laboratory to be between 0.2 – 0.3 g horizontal peak ground acceleration. These instruments were located at the Veterans Hospital, 5 miles southwest of LLNL, and in San Ramon, about 12 miles west of LLNL. In 2011, the Department of Energy (DOE) requested to know the status of our seismic instruments. We conducted a survey of our instrumentation systems and responded to DOE in a letter. During this survey, it was found that the recorders in Buildings 111 and 332 were not operational. The instruments on Nova had been removed, and only three of the 10 NIF instruments installed in 2005 were operational (two were damaged and five had been removed from operation at the request of the program). After the survey, it was clear that the site seismic instrumentation had degraded substantially and would benefit from an overhaul and more attention to ongoing maintenance. LLNL management decided to update the LLNL seismic instrumentation system. The updated system is documented in this report.

Stable Isotopic Variations in Precipitation in Southwest China

Institute of Scientific and Technical Information of China (English)

无

2006-01-01

This study analyzes the relationships of stable isotopes in precipitation with temperature, air pressure and humidity at different altitudes, and the potential influencing mechanisms of control factors on the stable isotopes in precipitation in Southwest China. There appear marked negative correlations of the δ18O in precipitation with precipitation amount, vapor pressure and atmospheric precipitable water (PW)at the Mengzi, Simao and Tengchong stations on the synoptic timescale; the marked negative correlations between the δ18O in precipitation and the diurnal mean temperature at 400 hPa, 500 hPa, 700 hPa and 850hPa are different from the temperature effect in middle-high-latitude inland areas. In addition, the notable positive correlation between the δ18O in precipitation and the dew-point deficit △Td at different altitudes is found at the three stations. Precipitation is not the only factor generating an amount effect. Probably,the amount effect is related to the variations of atmospheric circulation and vapor origins. On the annual timescale, the annual precipitation amount weighted-mean δ18O displays negative correlations not only with annual precipitation but also with annual mean temperature at 500 hPa. It can be deduced that, in the years with an abnormally strong summer monsoon, more warm and wet air from low-latitude oceans is transported northward along the vapor channel located in Southwest China and generates abnormally strong rainfall on the way. Meanwhile, the abnormally strong condensation process will release more condensed latent heat in the atmosphere, and this will lead to a rise of atmospheric temperature during rainfall but a decline of δ18O in the precipitation. On the other hand, in the years with an abnormally weak summer monsoon, the precipitation and the atmospheric temperature during rainfalls decrease abnormally but the δ18O in precipitation increases.

This article aimed at understanding nutritional knowledge, attitudes, and behaviors of homosexual persons living with HIV/AIDS in Chongqing, China. A cross sectional design using a valid and reliable survey was used. The survey was completed in Chongqing, Southwest China (n = 172). Knowledge of nutrition was deficient regarding sources of nutrients such as calcium and iron, relationships between diet/nutrients and disease, and only 36.1% of participants knew about the Balanced Diet Pagoda for Chinese. Eating habits did not meet the nutritional requirements, and a majority (59.3%) did not eat breakfast every day. The average score on the knowledge quiz was 51.8%. This study showed that homosexual persons with HIV/AIDS in China longed for nutrition knowledge, and this was supported by objective data. Efforts and targeted education programs aiming to improve their nutrition knowledge, attitudes, and behaviors need to be emphasized.

Analysis of students’ generated questions in laboratory learning environments

Directory of Open Access Journals (Sweden)

Juan Antonio Llorens-Molina

2012-03-01

Full Text Available In order to attain a reliable laboratory work assessment, we argue taking the Learning Environment as a core concept and a research paradigm that considers the factors affecting the laboratory as a particularly complex educational context. With regard to Laboratory Learning Environments (LLEs, a well known approach is the SLEI (Science Laboratory Environment Inventory. The aim of this research is to design and apply an alternative and qualitative assessment tool to characterize Laboratory Learning Environments in an introductory course of organic chemistry. An alternative and qualitative assessment tool would be useful for providing feed-back for experimental learning improvement; serving as a complementary triangulation tool in educational research on LLEs; and generating meaningful categories in order to design quantitative research instruments. Toward this end, spontaneous questions by students have been chosen as a reliable source of information. To process these questions, a methodology based on the Grounded Theory has been developed to provide a framework for characterizing LLEs. This methodology has been applied in two case studies. The conclusions lead us to argue for using more holistic assessment tools in both everyday practice and research. Likewise, a greater attention should be paid to metacognition to achieve suitable self-perception concerning students’ previous knowledge and manipulative skills.

Cat dissection and human cadaver prosection versus sculpting human structures from clay: A comparison of alternate approaches to human anatomy laboratory education

Science.gov (United States)

Waters, John R.

Dissection and vivisection are traditional approaches to biology laboratory education. In the case of human anatomy teaching laboratories, there is a long tradition of using human and animal cadaver specimens in the classroom. In a review of the literature comparing traditional dissection and vivisection lessons to alternative lessons designed to reduce the time spent dissecting or the numbers of animals used, we conclude that it is difficult to come to any conclusion regarding the efficacy of different approaches. An analysis of the literature is confounded because many studies have very low statistical power or other methodological weaknesses, and investigators rely on a wide variety of testing instruments to measure an equally varied number of course objectives. Additional well designed studies are necessary before educators can reach any informed conclusions about the efficacy of traditional versus alternative approaches to laboratory education. In our experiments, we compared a traditional cat dissection based undergraduate human anatomy lesson to an alternative where students sculpted human muscles onto plastic human skeletons. Students in the alternative treatment performed significantly better than their peers in the traditional treatment when answering both lower and higher order human anatomy questions. In a subsequent experiment with a similar design, we concluded that the superior performance of the students in the alternative treatment on anatomy exams was likely due to the similarity between the human anatomy representation studied in lab, and the human anatomy questions asked on the exams. When the anatomy questions were presented in the context of a cat specimen, students in the traditional cat dissection treatment outperformed their peers in the alternative treatment. In a final experiment where student performance on a human anatomy exam was compared between a traditional prosected human cadaver treatment and the alternative clay sculpting

Constructivist Learning Environment During Virtual and Real Laboratory Activities

Directory of Open Access Journals (Sweden)

Ari Widodo

2017-04-01

Full Text Available Laboratory activities and constructivism are two notions that have been playing significant roles in science education. Despite common beliefs about the importance of laboratory activities, reviews reported inconsistent results about the effectiveness of laboratory activities. Since laboratory activities can be expensive and take more time, there is an effort to introduce virtual laboratory activities. This study aims at exploring the learning environment created by a virtual laboratory and a real laboratory. A quasi experimental study was conducted at two grade ten classes at a state high school in Bandung, Indonesia. Data were collected using a questionnaire called Constructivist Learning Environment Survey (CLES before and after the laboratory activities. The results show that both types of laboratories can create constructivist learning environments. Each type of laboratory activity, however, may be stronger in improving certain aspects compared to the other. While a virtual laboratory is stronger in improving critical voice and personal relevance, real laboratory activities promote aspects of personal relevance, uncertainty and student negotiation. This study suggests that instead of setting one type of laboratory against the other, lessons and follow up studies should focus on how to combine both types of laboratories to support better learning.

min. Under these conditions each analysis takes the student about 10 min and two students are scheduled per 20 min block. Since the instrument is under computer control, students operate the computer during the run. As the peaks appear on the mass chromatogram, their mass spectra are obtained and the student decides which corresponds to product and evaluates product purity and the structure of impurities. There is ample time to display all spectra, conduct library searches, and print data. This relatively simple laboratory exercise has the advantage of allowing each student to carry out an analysis on his or her own product. The fact that a brominated product is obtained introduces a discussion of isotopic patterns in mass spectrometry. The experiment is scheduled to coincide with the lecture discussion of spectroscopic structure determination and after SN2 reactions have been covered. One of our mass spectrometer satellite data stations is interfaced with a "3-gun" projector in a large lecture hall allowing the display of actual mass spectra from our instrument to lecture sections.

Late Pliocene Depositional History and Paleoclimate Reconstructions of the Southwest Pacific

Royce, B.; Patterson, M. O.; Pietras, J.

2017-12-01

Drift deposits off the eastern margin of New Zealand are important archives for the paleoclimate and paleoceanographic history of the southwest Pacific. Ocean Drilling Program (ODP) Site 1123 is located on the North Chatham rise drift just North of the westerly wind driven Subtropical Front (STF) and provides a record of near continuous sediment deposition since the Miocene along the southwest Pacific deep western boundary current (DWBC). While the Miocene and Late Pleistocene portion of this record have been well studied, the Late Pliocene record is less well developed. Southern Ocean geological records demonstrate that Late Pliocene cooling is the transient time bracketing the warmer than present Early Pliocene and bipolar glaciation at 2.7 Ma. A newly developed, robust, and astronomically tuned long-term record of benthic δ13C from ODP Site 1123 spanning the Early to Late Pliocene implies a reduction in Southern Ocean ventilation and lowering of preformed values from waters sourced along the Antarctic margin during the Late Pliocene. Thus, Late Pliocene Southern Hemisphere cooling and sea ice expansion may have drastically reduced outgassing and increased the burial of heat into the deep ocean. South Atlantic records off the west coast of Africa demonstrate an increase in the flux of iron to the open ocean during this time potentially enhancing surface ocean productivity and providing an additional cooling mechanism. Currently, atmospheric transport of dust to the Southern Ocean is dominated by persistent mid-latitude circumpolar westerly winds; this is particularly relevant for dust sourced from New Zealand. The Late Pliocene to Early Pleistocene uplift of the North Island axial ranges and South Island southern alps potentially provided a greater amount of not only sediment to the deep ocean, but also wind blow dust to the Pacific sector of the Southern Ocean. We will present a detailed high-resolution sedimentological study on the development of the Chatham

Clinical laboratories are significant generators of infectious waste, including microbiological materials, contaminated sharps, and pathologic wastes such as blood specimens and blood products. Most waste produced in laboratories can be disposed of in the general solid waste stream. However, improper management of infectious waste, including mixing general wastes with infectious wastes and improper handling or storage, could lead to disease transmission. The aim of this study was to assess waste management processes used at clinical laboratories in Shiraz, Iran. One hundred and nine clinical laboratories participated In this cross sectional study, Data collection was by questionnaire and direct observation. Of the total amount of waste generated, 52% (by weight) was noninfectious domestic waste, 43% was non-sharps infectious waste and 5% consisted of sharps. There was no significant relationship between laboratory staff or manager education and the score for quality of waste collection and disposal at clinical laboratories. Improvements in infectious waste management processes should involve clearer, more uniformly accepted definitions of infectious waste and increased staff training.

Watson, Ian D; Wilkie, Patricia; Hannan, Amir; Beastall, Graham H

2018-04-09

Healthcare delivery and responsibility is changing. Patient-centered care is gaining international acceptance with the patient taking greater responsibility for his/her health and sharing decision making for the diagnosis and management of illness. Laboratory medicine must embrace this change and work in a tripartite collaboration with patients and with the clinicians who use clinical laboratory services. Improved communication is the key to participation, including the provision of educational information and support. Knowledge management should be targeted to each stakeholder group. As part of collaborative healthcare clinical laboratory service provision needs to be more flexible and available, with implications for managers who oversee the structure and governance of the service. Increased use of managed point of care testing will be essential. The curriculum content of laboratory medicine training programs will require trainees to undertake practice-based learning that facilitates interaction with patients, clinicians and managers. Continuing professional development for specialists in laboratory medicine should also embrace new sources of information and opportunities for collaborative healthcare.

Dietary patterns represent a broader picture of food consumption, and are better correlated with a variety of health outcomes. However, few studies have been conducted to explore the associations between dietary patterns and obesity in Southwest China. Data from the 2010-2012 National Nutrition Survey in the province of Yunnan, Southwest China, were analyzed ( n = 1604, aged 18-80 years). Dietary data were collected using the 24 h dietary recall over three consecutive days. Height, weight, and waist circumference were measured following standard methods. Exploratory factor analysis was used to identify dietary patterns. Logistic regression was used to explore the association between dietary patterns and obesity. Three distinct dietary patterns were identified, which were labeled as traditional, modern, and tuber according to their key components. With potential confounders adjusted, adults in the highest quartile of the modern pattern were at higher risk of general and central obesity (odds ratio (OR) 1.95, 95% confidence interval (CI) 1.15-3.48; OR 2.01, 95% CI 1.37-2.93). In contrast, adults in the highest quartile of the tuber pattern were at lower risk of general and central obesity (OR 0.34, 95% CI 0.15-0.61; OR 0.64, 95% CI 0.43-0.95) but at higher risk of underweight (OR 2.57, 95% CI 1.20-6.45). No significant association was found between the traditional pattern and obesity. Moreover, dietary pattern differences occurred due to the differences in socio-demographic characteristics. In conclusion, the modern dietary pattern was positively, and the tuber pattern negatively, associated with general and central obesity among adults in Southwest China.

Virtual laboratory for radiation experiments

2009-01-01

Simulation of alpha, beta and gamma radiation detection and measurement experiments which are part of real nuclear physics laboratory courses was realized with Monte Carlo method and JAVA Programming Language. As being known, establishing this type of laboratories are very expensive. At the same time, highly radioactive sources used in some experiments carries risk for students and also for experimentalists. By taking into consideration of those problems, the aim of this study is to setup a virtual radiation laboratory with minimum cost and to speed up the training of radiation physics for students with no radiation risk. Software coded possesses the nature of radiation and radiation transport with the help of Monte Carlo method. In this software, experimental parameters can be changed manually by the user and experimental results can be followed synchronous in an MCA (Multi Channel Analyzer) or an SCA (Single Channel Analyzer). Results obtained in experiments can be analyzed by these MCA or SCA panels. Virtual radiation laboratory which is developed in this study with reliable results and unlimited experimentation capability seems as an useful educational material. Moreover, new type of experiments can be integrated to this software easily and as a result, virtual laboratory can be extended.

We report the discovery of sipunculan worms from the Lower Cambrian Maotianshan Shale, near Kunming (southwest China). Their sipunculan identity is evidenced by the general morphology of the animals (sausage-shaped body with a slender retractable introvert and a wider trunk) and by other features, both external (e.g. perioral crown of tentacles, and hooks, papillae and wrinkle rings on the body surface) and internal (U-shaped gut, and the anus opening near the introvert-trunk junction). The three fossil forms (Archaeogolfingia caudata gen. et sp. nov., Cambrosipunculus tentaculatus gen. et sp. nov. and Cambrosipunculus sp.) have striking similarities to modern sipunculans, especially the Golfingiidae to which their evolutionary relationships are discussed. This study suggests that most typical features of extant sipunculans have undergone only limited changes since the Early Cambrian, thus indicating a possible evolutionary stasis over the past 520 Myr.

2017-09-01

The ideas of geological heritage and geological diversity have become very popular in the modern science. These are usually applied to geological domains or countries, provinces, districts, etc. Additionally, it appears to be sensible to assess heritage value of geological bodies. The review of the available knowledge and the field investigation of the Gachsaran Formation (lower Miocene) in southwest Iran permit to assign its features and the relevant phenomena to as much as 10 geological heritage types, namely stratigraphical, sedimentary, palaeontological, palaeogeographical, geomorphological, hydrogeological, engineering, structural, economical, and geohistorical types. The outstanding diversity of the features of this formation determines its high heritage value and the national rank. The geological heritage of the Gachsaran Formation is important to scientists, educators, and tourists. The Papoon and Abolhaiat sections of this formation are potential geological heritage sites, although these do not represent all above-mentioned types. The large territory, where the Gachsaran Formation outcrop, has a significant geoconservation and geotourism potential, and further inventory of geosites on this territory is necessary. Similar studies of geological bodies in North Africa and the Middle East can facilitate better understanding of the geological heritage of this vast territory.

Examination of the Effects of Dimensionality on Cognitive Processing in Science: A Computational Modeling Experiment Comparing Online Laboratory Simulations and Serious Educational Games

Science.gov (United States)

Lamb, Richard L.

2016-02-01

Within the last 10 years, new tools for assisting in the teaching and learning of academic skills and content within the context of science have arisen. These new tools include multiple types of computer software and hardware to include (video) games. The purpose of this study was to examine and compare the effect of computer learning games in the form of three-dimensional serious educational games, two-dimensional online laboratories, and traditional lecture-based instruction in the context of student content learning in science. In particular, this study examines the impact of dimensionality, or the ability to move along the X-, Y-, and Z-axis in the games. Study subjects ( N = 551) were randomly selected using a stratified sampling technique. Independent strata subsamples were developed based upon the conditions of serious educational games, online laboratories, and lecture. The study also computationally models a potential mechanism of action and compares two- and three-dimensional learning environments. F test results suggest a significant difference for the main effect of condition across the factor of content gain score with large effect. Overall, comparisons using computational models suggest that three-dimensional serious educational games increase the level of success in learning as measured with content examinations through greater recruitment and attributional retraining of cognitive systems. The study supports assertions in the literature that the use of games in higher dimensions (i.e., three-dimensional versus two-dimensional) helps to increase student understanding of science concepts.

Deng, M.; di, L.

2009-12-01

Computational approaches (e.g., computer-based data visualization, analysis and modeling) are critical for conducting increasingly data-intensive Earth science (ES) studies to understand functions and changes of the Earth system. However, currently Earth scientists, educators, and students have met two major barriers that prevent them from being effectively using computational approaches in their learning, research and application activities. The two barriers are: 1) difficulties in finding, obtaining, and using multi-source ES data; and 2) lack of analytic functions and computing resources (e.g., analysis software, computing models, and high performance computing systems) to analyze the data. Taking advantages of recent advances in cyberinfrastructure, Web service, and geospatial interoperability technologies, GeoBrain, a project funded by NASA, has developed a prototype computational cyber-laboratory to effectively remove the two barriers. The cyber-laboratory makes ES data and computational resources at large organizations in distributed locations available to and easily usable by the Earth science community through 1) enabling seamless discovery, access and retrieval of distributed data, 2) federating and enhancing data discovery with a catalogue federation service and a semantically-augmented catalogue service, 3) customizing data access and retrieval at user request with interoperable, personalized, and on-demand data access and services, 4) automating or semi-automating multi-source geospatial data integration, 5) developing a large number of analytic functions as value-added, interoperable, and dynamically chainable geospatial Web services and deploying them in high-performance computing facilities, 6) enabling the online geospatial process modeling and execution, and 7) building a user-friendly extensible web portal for users to access the cyber-laboratory resources. Users can interactively discover the needed data and perform on-demand data analysis and

Siu Hong Loh

2017-02-01

Full Text Available Atomic force microscopy (AFM has been used extensively in nanoscience research since its invention. Recently, many teaching laboratories in colleges, undergraduate institutions, and even high schools incorporate AFM as an effective teaching tool for nanoscience education. This paper presents an optical beam deflection (OBD based atomic force microscope, designed specifically for the undergraduate engineering laboratory as a teaching instrument. An electronic module for signal conditioning was built with components that are commonly available in an undergraduate electronic laboratory. In addition to off-the-shelf mechanical parts and optics, the design of custom-built mechanical parts waskept as simple as possible. Hence, the overall cost for the setup is greatly reduced. The AFM controller was developed using National Instruments Educational Laboratory Virtual Instrumentation Suite (NI ELVIS, an integrated hardware and software platform which can be programmed in LabVIEW. A simple yet effective control algorithm for scanning and feedback control was developed. Despite the use of an educational platform and low-cost components from the undergraduate laboratory, the developed AFM is capable of performing imaging in constant-force mode with submicron resolution and at reasonable scanning speed (approximately 18 min per image. Therefore, the AFM is suitable to be used as an educational tool for nanoscience. Moreover, the construction of the system can be a valuable educational experience for electronic and mechanical engineering students.

Full Text Available In engineering the pedagogical content of most formative programmes includes a significant amount of practical laboratory hands-on activity designed to deliver knowledge acquisition from actual experience alongside traditional face-to-face classroom based lectures and tutorials; this hands-on aspect is not always adequately addressed by current e-learning platforms. An innovative approach to e-learning in engineering, named computer aided engineering education (CAEE is about the use of computer aids for the enhanced, interactive delivery of educational materials in different fields of engineering through two separate but related components; one for classroom and another for practical hands-on laboratory work. The component for hands-on laboratory practical work focuses on the use of mixed reality (video-based augmented reality tools on mobile devices/platforms. This paper presents the computer aided engineering education (CAEE implementation of a laboratory experiment in micro-electronics that highlights some features such as the ability to closely implement an existing laboratory based hands-on experiment with lower associated costs and the ability to conduct the experiment off-line while maintaining existing pedagogical contents and standards.

The Role of Southwesterly Flow in MCS Formation During a Heavy Rain Event in Taiwan on 12 - 13 June 2005

Directory of Open Access Journals (Sweden)

Fang-Ching Chien

2015-01-01

Full Text Available This paper presents a numerical study of a heavy rain event that occurred in southern Taiwan in June 2005. From 11 - 13 June 2005, a weak Mei-yu front moved southeastward from China to Taiwan, while mesoscale convective systems (MCSs were developing and moving northward over the northern South China Sea (SCS. During the first day of the event the southwesterly flow intensified when a ridge associated with the Pacific high extended northwestward from the Philippines to the southern Taiwan Strait (TS. This pressure pattern produced a large northwestward pressure gradient force that created a southeasterly wind speed increase followed by intensification of the southwesterly flow through Coriolis acceleration. An low-level jet (LLJ formed consequently and transported moisture and unstable air toward the southwestern coast of Taiwan. MCSs were triggered in the southwesterly flow because the potentially unstable air was lifted in a low-level convergence and shearing vorticity environment. They intensified, became organized, and moved northeastward overland, resulting in heavy rainfall in southern Taiwan. On the second day, low pressure formed near the southern TS because of the combined effect of a travelling short-wave trough and a pressure reduction resulting from the latent heat release by the evolving MCSs. This pressure change produced down-gradient acceleration in the northeastward direction, resulting in southwesterly flow strengthening. The local wind acceleration was smaller than that of the first day because the dominant pressure system was local scale, while that of the first day was synoptic scale.

Lowenstern, Jacob B.

2013-01-01

Though volcanic eruptions are comparatively rare in the American Southwest, the States of Arizona, Colorado, New Mexico, Nevada, and Utah host Holocene volcanic eruption deposits and are vulnerable to future volcanic activity. Compared with other parts of the western United States, comparatively little research has been focused on this area, and eruption probabilities are poorly constrained. Monitoring infrastructure consists of a variety of local seismic networks, and ”backbone“ geodetic networks with little integration. Emergency response planning for volcanic unrest has received little attention by either Federal or State agencies. On October 18–20, 2012, 90 people met at the U.S. Geological Survey campus in Flagstaff, Arizona, providing an opportunity for volcanologists, land managers, and emergency responders to meet, converse, and begin to plan protocols for any future activity. Geologists contributed data on recent findings of eruptive ages, eruption probabilities, and hazards extents (plume heights, ash dispersal). Geophysicists discussed evidence for magma intrusions from seismic, geodetic, and other geophysical techniques. Network operators publicized their recent work and the relevance of their equipment to volcanic regions. Land managers and emergency responders shared their experiences with emergency planning for earthquakes. The meeting was organized out of the recognition that little attention had been paid to planning for or mitigation of volcanic hazards in the American Southwest. Moreover, few geological meetings have hosted a session specifically devoted to this topic. This volume represents one official outcome of the meeting—a collection of abstracts related to talks and poster presentations shared during the first two days of the meeting. In addition, this report includes the meeting agenda as a record of the proceedings. One additional intended outcome will be greater discussion and coordination among emergency responders, geologists

Safeguards training at Pacific Northwest Laboratory

In recent years considerable attention has been given to upgrading security education programs at facilities across the country. At Pacific Northwest Laboratory (PNL), a Laboratory-wide Safeguard Awareness Training Program has been established in order to raise the cognizance of the entire staff with regard to safeguards issues and concerns. This aggressive safeguards program involves a strong interface of physical security measure and material control and accountability systems. Within PNL, four distinct audiences were defined and a needs assessment analysis performed for each to determine specific training requirements. The target audiences identified were: material balance area (MBA) custodians, managers of material balance areas, material handlers, and new employees. Five safeguards training courses were created to meet the needs of those audiences. This paper discusses the development of the Safeguards Awareness Program at PNL and its benefits to the Laboratory

As part of the Grays Harbor Navigation Improvement Project, the Seattle District of the US Army Corps of Engineers has begun active use of the Southwest Ocean Disposal Site off Grays Harbor, Washington. This survey was to verify that the location of the area of high crab density observed during site selection surveys has not shifted into the Southeast Ocean Disposal Site. In June 1990, mean densities of juvenile Dungeness crab were 146 crab/ha within the disposal site and 609 crab/ha outside ad north of the disposal site. At nearshore locations outside the disposal site, juvenile crab density was 3275 crab/ha. Despite the low overall abundance, the spatial distribution of crab was such that the high crab densities in 1990 have remained outside the Southwest Ocean Disposal Site. The survey data have confirmed the appropriateness of the initial selection of the disposal site boundaries and indicated no need to move to the second monitoring tier. 8 refs., 9 figs., 2 tabs.

2013-03-01

Full Text Available This paper presents the results of an investigation about chemistry teaching laboratory, describing the potential of a methodology that combines theoretical and hands on activities about chemical reactions. This proposal explores the curriculum content of high school chemistry, highlighting the teaching of chemical reactions, seeking the establishment of inter-relationships between the theoretical and practical knowledge inherent in the processes of school knowledge in Chemistry, challenging teachers to think about experimental activities not as an isolated moment in their class, but as an integral part of it. The methodology was qualitative in nature, adopting semi-structured interviews as instruments for data collection. The research was conducted with eight teachers of chemistry and seventy students from the second grade of high school from a technical school in Rio de Janeiro state. The results of this study indicate that this approach appears as an alternative to conducting laboratory experimental activities, contributing to a more formative and informative, less technical and fragmented teaching of chemistry in Basic Education. The research also shows that this approach supports teachers on their reflection of teaching practices, as well as on the planning and execution of experimental activities. We conclude that pedagogical proposals that articulate theory and practice are more effective in promoting the learning of high school students.

Abstract Undergraduate biochemistry laboratory courses often do not provide students with an authentic research experience, particularly when the express purpose of the laboratory is purely instructional. However, an instructional laboratory course that is inquiry‐ and research‐based could simultaneously impart scientific knowledge and foster a student's research expertise and confidence. We have developed a year‐long undergraduate biochemistry laboratory curriculum wherein students determine, via experiment and computation, the function of a protein of known three‐dimensional structure. The first half of the course is inquiry‐based and modular in design; students learn general biochemical techniques while gaining preparation for research experiments in the second semester. Having learned standard biochemical methods in the first semester, students independently pursue their own (original) research projects in the second semester. This new curriculum has yielded an improvement in student performance and confidence as assessed by various metrics. To disseminate teaching resources to students and instructors alike, a freely accessible Biochemistry Laboratory Education resource is available at http://biochemlab.org. © 2015 The Authors Biochemistry and Molecular Biology Education published by Wiley Periodicals, Inc. on behalf of International Union of Biochemistry and Molecular Biology, 43(4):245–262, 2015.

From Laboratories to Classrooms: Involving Scientists in Science Education

Science.gov (United States)

DeVore, E. K.

2001-12-01

Scientists play a key role in science education: the adventure of making new discoveries excites and motivates students. Yet, American science education test scores lag behind those of other industrial countries, and the call for better science, math and technology education is widespread. Thus, improving American science, math and technological literacy is a major educational goal for the NSF and NASA. Today, funding for research often carries a requirement that the scientist be actively involved in education and public outreach (E/PO) to enhance the science literacy of students, teachers and citizens. How can scientists contribute effectively to E/PO? What roles can scientists take in E/PO? And, how can this be balanced with research requirements and timelines? This talk will focus on these questions, with examples drawn from the author's projects that involve scientists in working with K-12 teacher professional development and with K-12 curriculum development and implementation. Experiences and strategies for teacher professional development in the research environment will be discussed in the context of NASA's airborne astronomy education and outreach projects: the Flight Opportunities for Science Teacher EnRichment project and the future Airborne Ambassadors Program for NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). Effective partnerships with scientists as content experts in the development of new classroom materials will be described with examples from the SETI Institute's Life in the Universe curriculum series for grades 3-9, and Voyages Through Time, an integrated high school science course. The author and the SETI Institute wish to acknowledge funding as well as scientific and technical support from the National Science Foundation, the National Aeronautics and Space Administration, the Hewlett Packard Company, the Foundation for Microbiology, and the Combined Federated Charities.

What are the relationships between apolipoprotein (apo) A-I and apoB concentrations, the apoB/apoA-I ratio and the prevalences of dyslipidemia and metabolic syndrome (MS) in south-west Chinese women with polycystic ovary syndrome (PCOS). There is a relatively high incidence of dyslipidemia and MS in south-west Chinese women with PCOS, especially in patients without hyperandrogenism. Patients with dyslipidemia are more obese, and have a more adverse glucose and lipid metabolic profile and higher apoB levels and apoB/apoA-I ratio. The increased apoB levels and apoB/A1 ratio and the MS are strongly associated with PCOS, suggesting that there is an increased risk of cardiovascular diseases in these patients. Dyslipidemia and MS have been widely studied in women with PCOS, but to date no data from south-west Chinese subjects have been available. The apoB/apoA-I ratio has been reported to be strongly associated with MS and insulin resistance (IR) and to be a reliable parameter that reflects lipid disturbances and the potential to develop atherosclerosis, but its relationship with PCOS is unclear. DESIGN This case-control study included 406 patients with PCOS and 342 control women between 17 and 40 years of age from a population in south-west China during 2006-2011. The diagnosis of PCOS was based on the revised 2003 Rotterdam criteria. The control group, consisting of women with infertility due to a Fallopian obstruction or the husband's infertility, women undergoing a pre-pregnancy check and healthy volunteers, was recruited from the same hospital during the same period. All women were not taking any medication known to affect carbohydrate or lipid or hormone metabolism for at least 3 months prior to the study, and were studied during the follicular phase of their menstrual cycle. MS was assessed by the National Cholesterol Education Program-Adult treatment Panel (NCEP-ATP) III criteria modified for Asian populations. Dyslipidemia was defined by one or more of the

Based on the results of the radiological assessment, the Argonne National Laboratory Radiological Survey Group arrived at the following conclusions: (1) soil contaminated with the radionuclides 60 Co and 152 Eu of undetermined origin was detected in the southwest quadrant of the Building 010 site. 60 Co was also detected in one environmental sample taken from an area northwest of the site and in a borehole sample taken from the area that previously held the radioactive gas hold-up tanks. Uranium was detected in soil from a hole in the center of the building site and in a second hole southwest of the building site. In all cases, the radionuclide levels encountered in the soil were well below the criteria set by DOE for this site; and (2) the direct instrument readings at the surface of the site were probably the result of natural radiation (terrestrial and celestial), as well as shine from the material being stored at the nearby RMDF facility. There was no evidence that the contaminated soil under the asphalt pad contributed detectable levels to the total background readings

Conclusion: Most laboratory technicians in our study reported favourable perceptions of CME programmes, feeling that they increased professional confidence and competency. We recommend that core competencies be integrated into credentialing using profession-specific CME in a workplace setting. In addition, MLTs should be involved in designing the programmes as well. Further studies in a multicentre institution are needed to analyse the difference in perception among those who have attended CME and those who have not.

Adding value to laboratory medicine: a professional responsibility.

Science.gov (United States)

Beastall, Graham H

2013-01-01

Laboratory medicine is a medical specialty at the centre of healthcare. When used optimally laboratory medicine generates knowledge that can facilitate patient safety, improve patient outcomes, shorten patient journeys and lead to more cost-effective healthcare. Optimal use of laboratory medicine relies on dynamic and authoritative leadership outside as well as inside the laboratory. The first responsibility of the head of a clinical laboratory is to ensure the provision of a high quality service across a wide range of parameters culminating in laboratory accreditation against an international standard, such as ISO 15189. From that essential baseline the leadership of laboratory medicine at local, national and international level needs to 'add value' to ensure the optimal delivery, use, development and evaluation of the services provided for individuals and for groups of patients. A convenient tool to illustrate added value is use of the mnemonic 'SCIENCE'. This tool allows added value to be considered in seven domains: standardisation and harmonisation; clinical effectiveness; innovation; evidence-based practice; novel applications; cost-effectiveness; and education of others. The assessment of added value in laboratory medicine may be considered against a framework that comprises three dimensions: operational efficiency; patient management; and patient behaviours. The profession and the patient will benefit from sharing examples of adding value to laboratory medicine.

A lightning climatology of the South-West Indian Ocean

Full Text Available The World Wide Lightning Location Network (WWLLN data have been used to perform a lightning climatology in the South-West Indian Ocean (SWIO region from 2005 to 2011. Maxima of lightning activity were found in the Maritime Continent and southwest of Sri Lanka (>50 fl km⁻² yr⁻¹ but also over Madagascar and above the Great Lakes of East Africa (>10–20 fl km⁻² yr⁻¹. Lightning flashes within tropical storms and tropical cyclones represent 50 % to 100 % of the total lightning activity in some oceanic areas of the SWIO (between 10° S and 20° S.

The SWIO is characterized by a wet season (November to April and a dry season (May to October. As one could expect, lightning activity is more intense during the wet season as the Inter Tropical Convergence Zone (ITCZ is present over all the basin. Flash density is higher over land in November–December–January with values reaching 3–4 fl km⁻² yr⁻¹ over Madagascar. During the dry season, lightning activity is quite rare between 10° S and 25° S. The Mascarene anticyclone has more influence on the SWIO resulting in shallower convection. Lightning activity is concentrated over ocean, east of South Africa and Madagascar.

A statistical analysis has shown that El Niño–Southern Oscillation mainly modulates the lightning activity up to 56.8% in the SWIO. The Indian Ocean Dipole has a significant contribution since ~49% of the variability is explained by this forcing in some regions. The Madden–Julian Oscillation did not show significative impact on the lightning activity in our study.

Full Text Available This paper presents results from the IST KAII Trial project ReLAX - Remote LAboratory eXperimentation trial (IST 1999-20827, and contributes with a framework for a global remote laboratory experimentation network supported by a new business model. The paper presents this new Experiment Service Provider business model that aims at bringing physical experimentation back into the learning arena, where remotely operable laboratory experiments used in advanced education and training schemes are made available to a global education and training market in industry and academia. The business model is based on an approach where individual experiment owners offer remote access to their high-quality laboratory facilities to users around the world. The usage can be for research, education, on-the-job training etc. The access to these facilities is offered via an independent operating company - the Experiment Service Provider. The Experiment Service Provider offers eCommerce services like booking, access control, invoicing, dispute resolution, quality control, customer evaluation services and a unified Lab Portal.

Outsourcing of Academic Clinical Laboratories

American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.

Detailed gravity and ground magnetic data collected along five traverses across Midway Valley on the eastern flank of Yucca Mountain in southwest Nevada are described. These data were collected as part of an effort to evaluate faulting in the vicinity of proposed surface facilities for a potential nuclear waste repository at Yucca Mountain. Geophysical data show that Midway Valley is bounded by large gravity and magnetic anomalies associated with the Bow Ridge and Paintbrush Canyon faults, on the west side of Exile Hill and on the west flank of Fran Ridge, respectively. In addition, Midway Valley itself is characterized by a number of small-amplitude anomalies that probably reflect small-scale faulting beneath Midway Valley

Turtle riders: remoras on marine turtles in Southwest Atlantic

Full Text Available An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras (Echeneidae associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora and four turtle species (Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea are here recorded in symbiotic associations in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis (hitchhiking, albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.

Development of security engineering curricula at US universities

Garcia, M.L.

1998-08-01

The Southwest Surety Institute was formed in June 1996 by Arizona State University (ASU), New Mexico Institute of Mining and Technology (NM Tech), New Mexico State University (NMSU), and Sandia National Laboratories (SNL) to provide educational programs in Security Engineering, and to conduct research and development in security technologies. This is the first science-based program of its kind in the US, focused on educating Security Engineers to help government and industry address their security needs. Each member brings a unique educational capability to the Institute. NM Tech has a formidable explosives testing and evaluation facility. ASU is developing a Masters program in Security Engineering at their School of Technology located on a new campus in Mesa, Arizona. NMSU provides a Security Technology minor, merging programs in Criminal Justice and Engineering Technology. The Sandia National Laboratories security system design and evaluation process forms the basis for the Security Engineering curricula. In an effort to leverage the special capabilities of each university, distance education will be used to share courses among Institute members and eventually with other sites across the country.
