    Yuan Chaoqing; Liu Sifeng; Wu Junlong


    Energy issues receive more and more attention these days. And it is considered that technological progress is an essential approach to save energy. This essay is to analyze the relation between energy intensity and technological progress by Cobb-Douglas production function in which energy, labor, capital and technological progress are taken as independent variables. It proves that the growth of output per capital and output per labor will increase energy intensity while technological progress will decrease energy intensity. Empirical research on Chinese industry is used here to indicate technological progress greatly decreases energy intensity. Because of the interferences of Asian financial crisis, there is something abnormal in the data. So in the empirical research, average weaken buffer operator (ABWO) is applied to weaken the interference of Asian financial crisis to the fixed assets, energy and value added. The results of the empirical research show that technological progress decreases energy intensity of Chinese industry an average of 6.3% every year in China.

    To develop a searchable database of educational technologies used at schools and colleges of pharmacy. A cross-sectional survey design was used to determine what educational technologies were being used and to identify an individual at each institution who could serve as an information resource for peer-to-peer questions. Eighty-nine survey instruments were returned for a response rate of 75.4%. The resulting data illustrated the almost ubiquitous presence of educational technology. The most frequently used technology was course management systems and the least frequently used technology was microblogging. Educational technology use is trending toward fee-based products for enterprise-level applications and free, open-source products for collaboration and presentation. Educational technology is allowing educators to restructure classroom time for something other than simple transmission of factual information and to adopt an evidence-based approach to instructional innovation and reform.

  19. EMC Corporation Provides Colleges with a Course in Storage Technologies (United States)

    Van Sickle, Ed


    EMC Corporation, the world leader in data storage, created the EMC Academic Alliance Program to educate students on storage and close the education gap that exists. EMC developed a Storage Technology course to teach students about the design of storage technologies and the "big picture" of an information infrastructure. The course is "open" and focused on storage technologies, not products. College and universities use the course to teach students about a very important topic in IT: Storage. EMC collaborates with colleges and universities by providing the course, knowledge transfer sessions to faculty and program support. There is no cost to join and no cost to obtain the courses. EMC requires partners to sign an agreement for course use. Several colleges are using the course as an upper level elective and the course is taught by faculty. The alliance program has reduced faculty time to develop a storage course and time to learn the topic. Faculty is responsible for credentialing students and they supplement the course with additional materials. Students are being recruited for jobs by EMC and others, including internships. The Alliance program provides academic institutions with a way to differentiate. This paper will explain the program and the Storage Technology course.

  2. Sleeping with technology: cognitive, affective, and technology usage predictors of sleep problems among college students. (United States)

    Rosen, Larry; Carrier, Louis M; Miller, Aimee; Rokkum, Jeffrey; Ruiz, Abraham


    Sleep problems related to technology affect college students through several potential mechanisms including displacement of sleep due to technology use, executive functioning abilities, and the impact of emotional states related to stress and anxiety about technology availability. In the present study, cognitive and affective factors that influence technology usage were examined for their impact upon sleep problems. More than 700 US college students completed an online questionnaire addressing technology usage, anxiety/dependence, executive functioning, nighttime phone usage, bedtime phone location, and sleep problems. A path model controlling for background variables was tested using the data. The results showed that executive dysfunction directly predicted sleep problems as well as affected sleep problems through nighttime awakenings. In addition, anxiety/dependence increased daily smartphone usage and also increased nighttime awakenings, which, in turn, affected sleep problems. Thus, both the affective and cognitive factors that influence technology usage affected sleep problems. Copyright © 2016 National Sleep Foundation. Published by Elsevier Inc. All rights reserved.

  8. Cognitive Effects of Technology Over Four Years of College

    Directory of Open Access Journals (Sweden)

    Chad N. Loes


    Full Text Available Technology permeates higher education, yet less is known about the use of established technologies, such as email and other electronic communication mediums (e.g., discussion boards, listservs for instructional purposes on important student outcomes such as cognitive development. In this study, we use data from the Wabash National Study to estimate the effects of email and other electronic medium use for academic purposes on three measures of cognitive development over four years of college. To investigate this, we regress each measure of cognitive development on email and electronic medium use, while simultaneously controlling for a wide array of potential confounding influences. Net of these influences, we find that email and electronic medium use are positively associated with gains in students’ Need for Cognition. These same technologies fail to have more than a chance influence on students’ critical thinking skills, however. Lastly, email use is associated with gains in the Positive Attitudes Toward Literacy measure for Whites and females, whereas electronic medium use leads to gains in the same outcome for racial and ethnic minorities. While institutions consider newer technologies for instructional purposes, our findings suggest established technologies can play a powerful role in the development of students’ cognitive skills.

    Flinton, Michael E.


    The Spatial Information Technology Center (SITC) at Fulton-Montgomery Community College (FMCC) continued to fulfill its mission and charter by successfully completing its third year of operations under Congressional funding and NASA sponsorship. Third year operations (01 Oct 02 - 30 Sep 03) have been funded and conducted utilizing two authorized Research Grants NAG 13-00043 (via a one-year no-cost extension expiring Sep 03) and NAG 13-02053 (one-year no-cost extension expiring Sep 04). Drawdowns and reporting of fiscal activities for SlTC operations continues to pass through the Institute for the Application of Geo-spatial Technology (IAGT) at Cayuga Community College in Auburn, New York. Fiscal activity of the Center is reported quarterly via SF 272 to IAGT, thus this report contains only a budgetary overview and forecast of future expenditures for the remaining funds of NAG 13 - 02053. Funds from NAG 13 - 00043 were exhausted during the fourth quarter of fiscal year FY02 - 03, which necessitated initial draw down of NAG 13 - 02053. The IAGT receives no compensation for administrative costs as authorized and approved by NASA in each award budget. This report also includes the necessary addendums for each NAG award, as required by federal guidelines, though no reportable activities took place within this report period. Attached are the signed Report of New Technology/lnventions and a Final Property Report identifying qualifying equipment purchased by the Center. As an academic, economic and workforce development oriented program, the Center has made significant strides in bringing the technology, knowledge and applications of the spatial information technology field to the region it serves. Through the mission of the Center, the region's educational, economic development and work force communities have become increasingly educated to the benefits of spatial (Geospatial) technology, particularly in the region's K-12 arena. SlTC continues to positively affect the

  20. Characteristics of regents college nontraditional nuclear technology degrees

    International Nuclear Information System (INIS)

    DeSain, G.W.


    In 1971, the Board of Regents of The University of The State of New York created Regents College Degrees to assess academic knowledge of working adults and award college degrees based on demonstrated knowledge rather than time spent in a college classroom. It was founded on a basic premise that seemed radical to some but which is now widely accepted: What a person knows is more important than how or where that knowledge was acquired. Regents College degrees, therefore, are a different concept of a college: one that is an assessing institution rather than a teaching institution. It has no campus and offers no courses. Students can combine college credits from a variety of different sources int an accredited degree program. Staff and faculty evaluate that credit according to the requirements of the particular degree program. When all requirements are met, the Board or Regents of The University of The State of New York confers the degree

  1. College Students' Use of Technology to Communicate with Romantic Partners about Sexual Health Issues. (United States)

    Tannebaum, Michael


    To examine college students' technology-assisted sexual communication perceptions and practices alongside their face-to-face (F-t-F) sexual communication behaviors. 144 college students at a private university in the Northeast, U.S., completed a survey in October 2016. A cross-sectional online survey examined how college students use text messaging and private social media messaging to communicate with romantic partners about sexual health issues. Students who have communicated with romantic partners via technology reported being likely to do so again in the future, to perceive the effectiveness of technology-assisted sexual communication to be comparable to F-t-F sexual communication, and to be confident in their ability to initiate sexual communication with romantic partners via F-t-F communication. College students may see text messaging and social media messaging as useful for sexual communication, which has important implications for college health professionals who wish to promote frequent, effective sexual communication.

    This paper describes the achievements of a program in which technology education is provided to cultivate practical core engineers for low-level radiation. It was made possible by means of (1) an introductory education program starting at an early age and a continuous agenda throughout college days and (2) regional collaboration. First, with regard to the early-age introductory education program and the continuous education agenda, the subjects of study related to atomic energy or nuclear engineering were reorganized as “Subjects related to Atomic Power Education” for all grades in all departments. These subjects were included in the syllabus and the student guide book, emphasizing a continuous and consistent policy throughout seven-year college study, including the five-year system and additional two-year advanced course. Second, to promote practical education, the contents of lectures, experiments, and internships were enriched and realigned in collaboration with the Japan Atomic Energy Agency, Okayama University and The Cyugoku Electric Power Co., Inc. In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects were undertaken to enhance the educational and research activities. In consequence, it has been estimated that there is now a total of fourteen subject areas in atomic energy technology, more than eight-hundred registered students in the department, and thirteen members of the teaching staff related to atomic energy technology. Furthermore, the “Tsuyama model” is still being developed. This program was funded by the Ministry of Education, Culture, Sports, Science and Technology.

    This study describes the achievements of a program that provides technology education about radiation to develop practical core engineers, then the effects of the programed were discussed. An education program starting at an early age and continuous and consistent educational agendas through seven years of college has been constructed in collaboration with regional organizations. Subjects relating to atomic energy or nuclear engineering were regrouped as “Subjects Related to Atomic Power Education” for most grades in each department. These subjects were included in the syllabus and the student guide book to emphasize a continuous and consistent policy throughout the seven-year period of college study, comprising the five-year system and the additional two-year advanced course. Furthermore, the content of lectures, experiments, and internships was enriched and realigned in collaboration with the Japan Atomic Energy Agency (JAEA), Okayama University, and Chugoku Electric Power Co., Inc. Additional educational materials were developed from inspection visits by teaching staff to atomic energy facilities were also used in the classes. Two student experiment textbooks were developed to promote two of the subjects related to atomic energy: “Cloud Chamber Experiment” and “A Test of γ-ray Inverse Square Law.” In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects was undertaken to enhance educational and research activities. Some examples are as follows: “Study on the Relation between γ Dose Rate and Rainfall in Northern Okayama Area,” “Remote Sensing of Radiation Dose Rate by Customizing an Autonomous Robot,” and “Nuclear Reaction Analysis for Composition Measurement of BN Thin Films.” It should be noted that an atomic-energy-related education working group has been in place officially to continue the above activities in the college since 2011.

  20. Impact of technology-infused interactive learning environments on college professors' instructional decisions and practices (United States)

    Kuda Malwathumullage, Chamathca Priyanwada

    Recent advancements in instructional technology and interactive learning space designs have transformed how undergraduate classrooms are envisioned and conducted today. Large number of research studies have documented the impact of instructional technology and interactive learning spaces on elevated student learning gains, positive attitudes, and increased student engagement in undergraduate classrooms across nation. These research findings combined with the movement towards student-centered instructional strategies have motivated college professors to explore the unfamiliar territories of instructional technology and interactive learning spaces. Only a limited number of research studies that explored college professors' perspective on instructional technology and interactive learning space use in undergraduate classrooms exist in the education research literature. Since college professors are an essential factor in undergraduate students' academic success, investigating how college professors perceive and utilize instructional technology and interactive learning environments can provide insights into designing effective professional development programs for college professors across undergraduate institutions. Therefore, the purpose of this study was to investigate college professors' pedagogical reasoning behind incorporating different types of instructional technologies and teaching strategies to foster student learning in technology-infused interactive learning environments. Furthermore, this study explored the extent to which college professors' instructional decisions and practices are affected by teaching in an interactive learning space along with their overall perception of instructional technology and interactive learning spaces. Four college professors from a large public Midwestern university who taught undergraduate science courses in a classroom based on the 'SCALE-UP model' participated in this study. Major data sources included classroom

    Bernhardt, Jay M.; Usdan, Stuart; Mays, Darren; Martin, Ryan; Cremeens, Jennifer; Arriola, Kimberly Jacob


    Objective: This study used a two-group randomized design to assess the validity of measuring self-reported alcohol consumption among college students using the Handheld Assisted Network Diary (HAND), a daily diary assessment administered using wireless mobile devices. Method: A convenience sample of college students was recruited at a large, public university in the southeastern United States and randomized into two groups. A randomly assigned group of 86 students completed the daily HAND assessment during the 30-day study and a Timeline Followback (TLFB) at 30-day follow-up. A randomly assigned group of 82 students completed the paper-and-pencil Daily Social Diary (DSD) over the same study period. Data from the daily HAND assessment were compared with the TLFB completed at follow-up by participants who completed the HAND using 95% limits of agreement analysis. Furthermore, individual growth models were used to examine differences between the HAND and DSD by comparing the total drinks, drinking days, and drinks per drinking day captured by the two assessments over the study period. Results: Results suggest that the HAND captured similar levels of alcohol use compared with the TLFB completed at follow-up by the same participants. In addition, comparisons of the two study groups suggest that, controlling for baseline alcohol use and demographics, the HAND assessment captured similar levels of total drinks, drinking days, and drinks per drinking day as the paper-and-pencil DSD. Conclusions: The study findings support the validity of wireless mobile devices as a daily assessment of alcohol use among college students. PMID:19737502

  9. Design and Research on Platform to Enhance College Students’ Art Appreciation Capability Based on Modern Information Technology

    Directory of Open Access Journals (Sweden)

    Shen Xifei


    Full Text Available Nowadays, with the rapid development of modern information technology, the college students could not preferably choose and learn to enhance their own art appreciation capability. Therefore, the colleges and universities have a more urgent desire to organize, develop and provide a good platform to enhance the college students’ art appreciation capability based on modern information technology. This paper describes how to enhance the art appreciation capability in detail, and designs and analyzes the platform to enhance college students’ art appreciation capability based on modern information technology---the “Music Corner” and the “Dance Corner”, indicating that the exchange platform built with modern information technology can promotes the college students’ art appreciation capability. Finally, through the analysis of statistical results of the questionnaire, college students are fonder of art appreciation after the establishment of platform, more inclined to the comprehensive learning of art, more brave to express their own sense of art, and fonder of artistic creation.

    Energy Technology Data Exchange (ETDEWEB)



    The objectives for this project were to create the laboratory facilities to deliver recently created and amended curriculum in the areas of energy creation, storage, and delivery in the transportation and stationary power sectors. The project scope was to define the modules, courses and programs in the emerging energy sectors of the stationary power and transportation industries, and then to determine the best equipment to support instruction, and procure it and install it in the laboratories where courses will be taught. Macomb Community College had a curriculum development grant through the Department of Education that ran parallel to this one where the energy curriculum at the school was revised to better permit students to gain comprehensive education in a targeted area of the renewable energy realm, as well as enhance the breadth of jobs addressed by curriculum in the transportation sector. The curriculum development and experiment and equipment definition ran in parallel, and resulted in what we believe to be a cogent and comprehensive curriculum supported with great hands-on experiments in modern labs. The project has been completed, and this report will show how the equipment purchases under the Department of Energy Grant support the courses and programs developed and amended under the Department of Education Grant. Also completed is the tagging documentation and audit tracking process required by the DOE. All materials are tagged, and the documentation is complete as required.

  20. College students' use of communication technology with parents: comparisons between two cohorts in 2009 and 2011. (United States)

    Ramsey, Meagan A; Gentzler, Amy L; Morey, Jennifer N; Oberhauser, Ann M; Westerman, David


    Although communication technology is beneficial to maintain important close relationships, not all findings suggest that communication technology use between college students and their parents is indicative of positive adjustment or relational qualities. A study in 2009 found that only 24.2% of college students used a social networking site (SNS) to communicate with a parent, yet those students reported more loneliness, anxious attachment, and conflict with their parent (Gentzler et al., 2011 ). Because technology and trends in use change rapidly, we investigated a new cohort of college students 2 years later to determine if rates of using communication technology with parents and their links to student adjustment have changed. Comparisons between 2009 and 2011 samples indicated that in-person contact and telephone use did not vary across cohorts. However, texting and SNS use with parents became more common, and using e-mail with parents declined. Consistent with the 2009 data, students' phone use with parents was related to positive relationship qualities (satisfaction, intimacy, support, instrumental aid). In the new 2011 sample, e-mail was linked to aid. However, the present findings indicate students' SNS use with parents is no longer linked to maladaptive outcomes. The study highlights how quickly the use and implications of communication technology changes, and suggests that communication patterns may reflect broader psychosocial adjustment and parent-child dynamics.

    Choi, Jong Hak; Lee, Sang Suk; Kim, Young Il; Kwon, Dal Gwan; Kim, Heung Tae; Lim, Han Young


    The education of radiologic technology began in the regular institute of higher education in Korea in 1963. Up to now from then, our education to bring up the radiologic technologists has developed greatly in quality and quantity, and now departments of radio-technology are founded in the 16 junior colleges in March, 1995. This study was done to verify the necessity and propriety to reform the education system of radiologic technology which was run as two or three year system of college curriculum for 32 years since 1963, and to search for the method to reform in the future. We got the following results from this research. 1. In the survey, on the desirable education year for radiologic technologists, 63.9 % of professors of department of radio-technology and 63.0 % of radiologic technologists chose the 4 year system, 27.9 % of professors and 34.6 % of radiologic technologists chose the 4 year system added to graduate school. 2. In the survey, on the future development of radiologic equipment and technique, 67.2 % of professors of department of radiologic technology and 86.4 % of radiologic technologists have a view of 'revolutional development'.

  8. Homeroom Activities in a College of Technology Based on the Master Plan (United States)

    Fuchida, Kunihiiko; Murata, Hideaki; Yuji, Junichiro

    Homeroom (HR) activities have an important role in engineering education at technical colleges. Yatsushiro National College of Technology has made a master plan for them and has been putting the plan into practical use since 2002. This plan is comprehensive and has two main categories, social education and career guidance, both being composed of three sub-categories (e.g., self-understanding and making future plans) . Based on the master plan, each HR teacher makes his own plan for HR activities for his classroom at the beginning of the academic year. We have reached a consensus to share our practice and to improve HR activities for years to come. We also recognize that to carry out HR activities based on a master plan that reflects the school's educational goals is essential in order to train students who are well-prepared, both as engineers and as humans.

  9. The value of communication in changing public perception on nuclear technology: an experience with college students

    International Nuclear Information System (INIS)

    Soares, Wellington Antonio


    Nowadays public acceptance is the most frequent keyword used in the Brazilian nuclear scenario with the revival of the nuclear program, in which the construction of more nuclear power plants and a national radioactive waste repository are expected. The acceptance of such activities is tightly linked to a strategic communication plan, the effective tool to be implemented if success is intended. Isolated communication actions are being done in the nuclear area and this paper presents one example of them, describing the experience with college students from two educational institutions, who attended the lecture 'Nuclear technology: prejudice, fundamentals, applications and challenges'. Opinion surveys were done before and after each event, to know the opinions towards nuclear technology. The surveys were based on the choice of three words from about 10 not ordered stimulating keywords and each participant was invited to choose the first three ones that could represent the image he/she had when faced with the theme 'nuclear technology'. The lecture included topics covering positive and negative points of the nuclear technology. The measured results after the lectures shown positive perspective in the first images associated with the nuclear technology, despite focus on accidents was given in the final part of the event. The results show that some effectiveness on the target public was achieved in terms of bringing new perceptions on this technology. It is expected that this article can contribute somehow to the discussion of public acceptance of nuclear technology in Brazil. (author)

  12. Douglas-Fir Tussock Moth- and Douglas-Fir Beetle-Caused Mortality in a Ponderosa Pine/Douglas-Fir Forest in the Colorado Front Range, USA

    Directory of Open Access Journals (Sweden)

    José F. Negrón


    Full Text Available An outbreak of the Douglas-fir tussock moth, Orgyia pseudotsugata McDunnough, occurred in the South Platte River drainage on the Pike-San Isabel National Forest in the Colorado Front Range attacking Douglas-fir, Pseudotsuga menziesii (Mirb. Franco. Stocking levels, species composition, and tree size in heavily and lightly defoliated stands were similar. Douglas-fir tussock moth defoliation resulted in significant Douglas-fir mortality in the heavily defoliated stands, leading to a change in dominance to ponderosa pine, Pinus ponderosa Lawson. Douglas-fir beetle, Dendroctonus pseudotsuqae Hopkins, populations increased following the defoliation event but caused less mortality, and did not differ between heavily and lightly defoliated stands. Douglas-fir tussock moth-related mortality was greatest in trees less than 15 cm dbh (diameter at 1.4 m above the ground that grew in suppressed and intermediate canopy positions. Douglas-fir beetle-related mortality was greatest in trees larger than 15 cm dbh that grew in the dominant and co-dominant crown positions. Although both insects utilize Douglas-fir as its primary host, stand response to infestation is different. The extensive outbreak of the Douglas-fir tussock moth followed by Douglas-fir beetle activity may be associated with a legacy of increased host type growing in overstocked conditions as a result of fire exclusion.

    Deaf learners are a highly heterogeneous group who demonstrate varied levels of academic achievement and attainment. Most prior research involving this population has focused on factors facilitating academic success in young deaf children, with less attention paid to older learners. Recent studies, however, have suggested that while factors such as early cochlear implantation and early sign language fluency are positively associated with academic achievement in younger deaf children, they no longer predict achievement once children reach high school age. This study, involving data from 980 college-bound high school students with hearing loss, examined relations between academic achievement, communication variables (audiological, language), and use of assistive technologies (e.g., cochlear implants [CIs], FM systems) and other support services (e.g., interpreting, real-time text) in the classroom. Spoken language skills were positively related to achievement in some domains, while better sign language skills were related to poorer achievement in others. Among these college-bound students, use of CIs and academic support services in high school accounted for little variability in their college entrance examination scores. © The Author 2017.

  18. Rethinking Teaching in STEM Education in a Community College: Role of Instructional Consultation and Digital Technologies (United States)

    Kurland, Shelley Chih-Hsian

    Community college faculty members educate almost half of all U.S. undergraduates, who are often more diverse and more academically underprepared when compared to undergraduate students who attend four-year institutions. In addition, faculty members in community colleges are facing increased accountability for meeting student learning outcomes, expectations to adjust their teaching practices to include active learning practices, and expectations to incorporate more technologies into the classroom. Faculty developers are one of the support structures that faculty members can look to in order to meet those challenges. A survey of literature in faculty development suggests that instructional consultation can play an important role in shaping and transforming teaching practices. Hence, this action research study examined my work using instructional consulting with four full-time STEM faculty colleagues in order to examine and shape their teaching practices with and without the use of digital technologies. The two foci of the research, examining shifts in faculty participants' teaching practices, and my instructional consulting practices, were informed by Thomas and Brown's (2011) social view of learning and the concept of teaching and learning in a "co-learning" environment. Two dominant factors emerged regarding faculty participants' shift in teaching practices. These factors concerned: 1) the perception of control and 2) individual faculty participant's comfort level, expectations, and readiness. In addition to these two dominant factors, the instructional consultation process also supported a range of shifts in either mindset and/or teaching practices. My analysis showed that the use of digital technologies was not an essential factor in shifting faculty participant mindset and/or teaching practices, instead digital technologies were used to enhance the teaching process and students' learning experiences.

  3. The Use of Interactive Technologies to Improve Student Learning of Physics from Middle School to College (United States)

    Sheldon, Peter; Wellington, Tracey


    The Physics Department at Randolph-Macon Woman's College, a liberal arts women's college of 720, has traditionally turned out approximately 0.6 majors/year. We have invigorated the program by adding community (e.g. SPS, physical space, organized activities), adding a significant technical component (e.g. web-assisted and computer interfaced labs and more technology in the classes [1]), and incorporating new learning techniques (JITT, Physlets, Peer Instruction [2], Interactive DVD's, and using the Personal Response System [3]). Students have responded well as evidenced by significant increases in enrollments as well as strong scores on the FCI. As an offshoot of this original project supported by the NSF, we have applied some of these teaching methods to teach younger children and teachers of younger children. In this presentation, we will discuss the implementation of the new curricular developments and the specific changes we have seen and hope to see in student learning. [1] This work is supported in part by the NSF CCLI Program under grant DUE-9980890. [2] See, for example, the project Galileo website for a description of all of these techniques.

  4. Information and communication technology related needs of college and university students with disabilities

    Directory of Open Access Journals (Sweden)

    Catherine S. Fichten


    Full Text Available Purpose: To explore variables related to how well the information and communication technologies (ICTs related needs of students with different disabilities are being met on campus at institutions of higher education, at home and in e-learning contexts. We also explore the disciplines and programmes pursued by students with different disabilities and the specialised ICTs they use. Method: A total of 1,354 Canadian university and junior/community college students with various disabilities completed the POSITIVES Scale. Results: Post-secondary students often have several disabilities which may affect how easily they can use ICTs. Students’ disabilities also influence the specialised ICTs they use and how well their ICT-related needs are being met. While the findings indicate that, overall, students’ ICT-related needs are generally well met, the results also show that these are better met on campus than at home, and at colleges than at universities. This is not related to institution size or to students’ disciplines. Conclusions: Our results show more favourable than unfavourable findings. Nevertheless, there are concerns around the availability of computers with adaptive software/hardware in specialised laboratories as well as with institutional ICT loan programmes; funding for ICTs for personal use; training, both on and off campus; and technical support off campus.

    Wei, Xin; Yu, Jennifer W; Shattuck, Paul; McCracken, Mary; Blackorby, Jose


    Little research has examined the popular belief that individuals with an autism spectrum disorder (ASD) are more likely than the general population to gravitate toward science, technology, engineering, and mathematics (STEM) fields. This study analyzed data from the National Longitudinal Transition Study-2, a nationally representative sample of students with an ASD in special education. Findings suggest that students with an ASD had the highest STEM participation rates although their college enrollment rate was the third lowest among 11 disability categories and students in the general population. Disproportionate postsecondary enrollment and STEM participation by gender, family income, and mental functioning skills were found for young adults with an ASD. Educational policy implications are discussed.

    Nakano, Wataru; Ishikawa, Nozomi; Matsuda, Kanaho; Ono, Masatsugu

    We introduce the internationalization promotion program conducted in Tomakomai National College of Technology (TNCT) . In order for the students to improve their international understanding and communication skills, the program was undertaken by means of collaborative education and distance education. TNCT delegates consisting of 2 teachers, 6 students, an office staff, and an engineer were sent to New Zealand, and worked on a project in cooperation with faculty members of Eastern Institute of Technology, Hawke‧s Bay (EIT) . The students explored environmental issues through discussions with other international students. At the end of the two-week on-site project, they reported the result via a video conferencing system. Additionally, this system served as a medium for international exchange in an intercultural communication class. Since the most of the students did not go to NZ, it was a good opportunity for them to communicate with people overseas. We discuss the effectiveness of both the collaborative education on practical topics and the distance education using a video conferencing system.

  19. The history of Imperial College London 1907-2007 higher education and research in science, technology and medicine

    CERN Document Server

    Gay, Hannah


    This is the first major history of Imperial College London. The book tells the story of a new type of institution that came into being in 1907 with the federation of three older colleges. Imperial College was founded by the state for advanced university-level training in science and technology, and for the promotion of research in support of industry throughout the British Empire. True to its name the college built a wide number of Imperial links and was an outward looking institution from the start. Today, in the post-colonial world, it retains its outward-looking stance, both in its many international research connections, and with staff and students from around the world. Connections to industry and the state remain important. The College is one of Britain's premier research and teaching institutions, including now medicine alongside science and engineering. This book is an in-depth study of Imperial College; it covers both governance and academic activity within the larger context of political, economic a...

    Nagasawa, Yoshinori; Demura, Shin-Ichi; Shimada, Shigeru


    Aim This study clarified the characteristics of life habits of obese Japanese male students at the National Colleges of Technology, Japan. Materials and methods Healthy students aged 15-19 years answered a questionnaire containing 21 items on the following five categories of life habits: general exercise, meals, sleeping, leisure activity and illness or injury history. The subjects were divided into three groups based on the criteria of body mass index (BMI) and body fat percentage (%BF): non-obese (%BF time, bedtime and amount of time spent walking, sleeping and watching TV per day were examined using one-way analysis of variance (ANOVA) and chi-square tests for each item. Results The overweight obese and hidden obese groups engaged in less exercise time, were more likely to eat until they were full at meals and were less likely to eat between meals or late at night than the non-obese group. In addition, the non-obese group had significantly later waking times and significantly less TV-watching time than the overweight obese group. There were no significant differences with respect to leisure activity and illness or injury history among the three groups. Many students in all groups had regular waking times and were not performing any leisure activities. Conclusion The findings suggest that obese students may need further guidance to help them maintain a healthy life and appropriate weight.

  5. Measuring Changes in Interest in Science and Technology at the College Level in Response to Two Instructional Interventions (United States)

    Romine, William L.; Sadler, Troy D.


    Improving interest in science, technology, engineering, and mathematics (STEM) is crucial to widening participation and success in STEM studies at the college level. To understand how classroom and extracurricular interventions affect interest, it is necessary to have appropriate measurement tools. We describe the adaptation and revalidation of a previously existing multidimensional instrument to the end of measuring interest in environmental science and technology in college nonscience majors. We demonstrate the revised instrument's ability to detect change in this group over an 8-week time period. While collection of demographic information was not part of the study design, participating students were similar in that they hailed from three environmental science nonmajor classes sharing a common syllabus and instructional delivery method. Change in interest was measured in response to two types of scientific literature-based learning approaches: a scientific practice approach and a traditional, quiz-driven approach. We found that both approaches led to moderate gains in interest in learning environmental science and careers in environmental science across an 8-week time period. Interest in using technology for learning increased among students using the scientific practice approach; in contrast, the same measure decreased among students using the reading/quiz approach. This result invites the possibility that interest in using technology as a learning tool may relate to technological literacy, which must be taught explicitly in the context of authentic inquiry experiences.

  6. Obituary: Douglas H. Sampson, 1925-2002 (United States)

    Mészáros, Peter; Clark, Robert E. H.; Zhang, Honglin; Fontes, Christopher J.


    Douglas H. Sampson, a renowned theoretical atomic physicist and a professor emeritus of astronomy and astrophysics at The Pennsylvania State University, passed away on 8 December 2002, in State College, Pennsylvania, of a hemorrhagic stroke. He had retired in 1997 after 32 years of service to the University and had maintained an active research program up to the day of his death. Doug, as he was universally known to his friends and colleagues, was born in Devils Lake, North Dakota on 19 May 1925. His parents, Abner and Mabel Sampson, were farmers. He was raised without running water or electricity on a farm, homesteaded by his ancestors in Edmore, North Dakota. He was one of two children in his class at a two-room rural elementary school and graduated as valedictorian from Edmore High School in 1944. No physics classes or advanced mathematics classes were offered in his small high school. In 1956, he was married to Carlyn Grutzner. During Doug Sampson's military service in the United States Army from February 1945 until December 1946, he was selected as a MP (Military Policeman) in the Philippines. His military experience provided him with the opportunity to attend college under the GI Bill. Because he had to work on the family farm, he started college a month later every fall and took exams a month earlier each spring. Nevertheless, Sampson graduated as co-salutatorian from Concordia College, Moorhead, Minnesota in 1951 with a BA degree with majors in physics and mathematics. Afterwards he received his MS and PhD degrees in theoretical physics from Yale University in 1953 and 1956 under the guidance of Henry Margenau. Sampson then became a staff member of the Theoretical Division of the Los Alamos National Laboratory until 1961. While there he performed calculations of fundamental atomic cross sections used in the determination of opacities for radiation transport simulations. The calculation of high quality atomic data would end up being a life long pursuit

    Samson M. Lausa


    Full Text Available Over the past years educational institutions have been investing increasingly substantial amount of money in integrating Information Technology (IT in the course of educational services delivery with the objective of improving operational efficiency and competitive advantage. The important role IT plays in educational institutions is unquestionable. It is regarded as a critical factor of innovation for growth and survival. The evaluation of the impact of this innovation in the educational system drives the researcher to undertake a study on Operational Efficiency of Information Technology and Organizational Performance of State Universities and Colleges (SUCs of Region VI, Philippines. Descriptive method was used utilizing a validated survey questionnaire which also involved the desk and field research conducted by a panel of two field researchers including the researcher himself covering selected SUCs of Region VI. Deans or department heads and faculty of the different colleges or departments, administrative and academic officials constitute the respondents of the study. Stratified proportional random sampling and purposive sampling were used in the study. Results of the study were viewed and analyzed using the Mean and the Pearson r Correlation Coefficient. Findings revealed that the operational efficiency of the SUCs of Region VI is moderately efficient while the majority of colleges/universities are performing moderately efficient. The study also revealed that the organizational performance of SUCs and the majority of colleges/universities are performing very satisfactory. Likewise, the findings also showed a significant relationship between the operational efficiency of information technology and organizational performance of SUCs. However, a significant relationship between operational efficiency and organizational performance of SUCs in instruction does not exist while a significant relationship exists in research, extension and

  10. A Technology-Mediated Behavioral Weight Gain Prevention Intervention for College Students: Controlled, Quasi-Experimental Study. (United States)

    West, Delia Smith; Monroe, Courtney M; Turner-McGrievy, Gabrielle; Sundstrom, Beth; Larsen, Chelsea; Magradey, Karen; Wilcox, Sara; Brandt, Heather M


    Both men and women are vulnerable to weight gain during the college years, and this phenomenon is linked to an increased risk of several chronic diseases and mortality. Technology represents an attractive medium for the delivery of weight control interventions focused on college students, given its reach and appeal among this population. However, few technology-mediated weight gain prevention interventions have been evaluated for college students. This study examined a new technology-based, social media-facilitated weight gain prevention intervention for college students. Undergraduates (n =58) in two sections of a public university course were allocated to either a behavioral weight gain prevention intervention (Healthy Weight, HW; N=29) or a human papillomavirus (HPV) vaccination awareness intervention (control; N=29). All students were enrolled, regardless of initial body weight or expressed interest in weight management. The interventions delivered 8 lessons via electronic newsletters and Facebook postings over 9 weeks, which were designed to foster social support and introduce relevant educational content. The HW intervention targeted behavioral strategies to prevent weight gain and provided participants with a Wi-Fi-enabled scale and an electronic physical activity tracker to facilitate weight regulation. A repeated-measures analysis of variance was conducted to examine within- and between-group differences in measures of self-reported weight control practices and objectively measured weight. Use of each intervention medium and device was objectively tracked, and intervention satisfaction measures were obtained. Students remained weight stable (HW: -0.48+1.9 kg; control: -0.45+1.4 kg), with no significant difference between groups over 9 weeks (P =.94). However, HW students reported a significantly greater increase in the number of appropriate weight control strategies than did controls (2.1+4.5 vs -1.1+3.4, respectively; P =.003) and there was no increase in

    Yotsuyanagi, Takao; Ikeda, Senri; Suzuki, Katsuhiko; Kobayashi, Hiroshi; Sakuraba, Hiroshi; Shoji, Akira; Itoh, Masahiko

    Creativity is the most fundamental keyword for engineers to solve the various problems in manufacturing products. This engineering “learning” cannot be achieved without the real experiences, especially by the teens who have the curiosity to know everything. New educational program has been innovated in Miyagi National College of Technology. This new curriculum started as “03C” in 2003. It involves two laboratories for mixed-departments type grouping, which intend to cultivate the creative ability for the 2nd year students in College Course and the 1st year students in Advanced Course as Engineering Design. This paper presents the trial of the new educational program on the cultivating creative ability designed for teen-agers, and discusses the processes in detail, results and further problems. This program will progress still more with continuous improvement of manufacturing subjects in cooperative with educational-industrial complex.

In addition to developing a comprehensive research agenda, four major programs were begun to meet these goals. This report summarizes the 1990--1991 progress.

  14. The Role of Executive Functioning and Technological Anxiety (FOMO in College Course Performance as Mediated by Technology Usage and Multitasking Habits

    Directory of Open Access Journals (Sweden)

    Larry D. Rosen


    Full Text Available This study investigated how technology use impacts academic performance. A proposed model postulated that academic performance could be predicted by a cognitive independent variable-executive functioning problems-and an affective independent variable-technological anxiety or FOMO (fear of missing out-mediated by how students choose to use technology. An unobtrusive smartphone application called “Instant Quantified Self” monitored daily smartphone unlocks and daily minutes of use. Other mediators included self-reported smartphone use, self-observed studying attention, self-reported multitasking preference, and a classroom digital metacognition tool that assessed the student’s ability to understand the ramifications of technology use in the classroom that is not relevant to the learning process. Two hundred sixteen participants collected an average of 56 days of “Instant” application data, demonstrating that their smartphone was unlocked more than 60 times a day for three to four minutes each time for a total of 220 daily minutes of use. Results indicated that executive functioning problems predicted academic course performance mediated by studying attention and a single classroom digital metacognition subscale concerning availability of strategies of when to use mobile phones during lectures. FOMO predicted performance directly as well as mediated by a second classroom digital metacognition concerning attitudes toward mobile phone use during lectures. Implications for college students and professors include increasing metacognition about technology use in the classroom and taking “tech breaks” to reduce technology anxiety.

  15. Automated Sensing of Douglas Fir Bud-Burst (United States)

    Lintz, H. E.; Kruger, A.; Wagner, D. A.; Tenney, I. J.


    The timing of plant biological events such as budburst in the spring can have major impacts on plant productivity and ecosystem carbon balance. While research efforts that address the timing of events is gaining considerable momentum, the technology available for sensing and recording the timing of events is limited, especially for trees. Thus, researchers often perform manual measurements, which can be time-consuming and labor-intensive. This has resulted in efforts such as Project BudBurst, a network of professional and volunteer observers across the United States that monitor plants as seasons change. Access to forest trees can be difficult during periods of greatest interest, such as when buds open in the spring. For example, high elevation, snow, and melting snow during the spring hamper access to trees in alpine regions. Researchers at Oregon State University and The University of Iowa are developing instrumentation for automating sensing of budburst in Douglas firs. While the instrumentation targets Douglas firs, it can find application in studying budburst in other species. We present an initial bud-burst sensor that uses optical techniques to sense bud opening. An optical fiber illuminates a target bud with modulated light, a second fiber detects, and guides reflect light to a photodetector and signal processing electronics. Changes in the reflected light indicate the budburst. The instrumentation exploits advances in microelectronics, particularly miniaturization and low power consumption, and uses advanced signal processing techniques such as lock-in detection. The instrumentation records the reflected light every 15 minutes on high-capacity, non-volatile Flash media. Power consumption is very low and sensors have an extrapolated, continuous operating time more than 9 months, suggesting their deployment in the fall, and retrieval in the following spring. We believe the sensor will enable a caliber of research not yet achievable owing to the difficulty of

  3. Student and high-school characteristics related to completing a science, technology, engineering or mathematics (STEM) major in college (United States)

    LeBeau, Brandon; Harwell, Michael; Monson, Debra; Dupuis, Danielle; Medhanie, Amanuel; Post, Thomas R.


    Background: The importance of increasing the number of US college students completing degrees in science, technology, engineering or mathematics (STEM) has prompted calls for research to provide a better understanding of factors related to student participation in these majors, including the impact of a student's high-school mathematics curriculum. Purpose: This study examines the relationship between various student and high-school characteristics and completion of a STEM major in college. Of specific interest is the influence of a student's high-school mathematics curriculum on the completion of a STEM major in college. Sample: The sample consisted of approximately 3500 students from 229 high schools. Students were predominantly Caucasian (80%), with slightly more males than females (52% vs 48%). Design and method: A quasi-experimental design with archival data was used for students who enrolled in, and graduated from, a post-secondary institution in the upper Midwest. To be included in the sample, students needed to have completed at least three years of high-school mathematics. A generalized linear mixed model was used with students nested within high schools. The data were cross-sectional. Results: High-school predictors were not found to have a significant impact on the completion of a STEM major. Significant student-level predictors included ACT mathematics score, gender and high-school mathematics GPA. Conclusions: The results provide evidence that on average students are equally prepared for the rigorous mathematics coursework regardless of the high-school mathematics curriculum they completed.

  5. GigaPan Technology to Enhance In-Class and In-Field Learning in Community College Settings (United States)

    Villalobos, J. I.; Bentley, C.


    Community college students account for over 40% of all undergraduates in the United States as well as the majority of minority and non-traditional students attending undergraduate courses. Implementing innovative, cost effective, and formative pedagogies to the diverse backgrounds of students that typically enroll at a community is often a challenge. Interactive pedagogies in geology pose a unique challenge considering that students gain the most long-term knowledge when topics covered in a course are exposed to them in outdoor settings where they are allowed to explore and make connections. The ability to expose students to real world examples is challenging to many community college faculty considering that that many; lack funds or means for transportation of students, do not have administrative support on such endeavors, teach evening or night classes, or have a high percentage of students who are physically limited or have obligations to work and family. A joint collaborative between El Paso Community College (EPCC) and Northern Virginia Community College (NOVA) has explored the usage of GigaPan technology to create multi-layered online material to minimize these issues faced by many community college faculty and students. The primary layer of the online material is GigaPans of local geological sites that highlight large-scale structures in the El Paso, Texas region that are commonly used in local field trips and lab book material. The second layer is of Macro-GigaPans of hand samples of key outcrops from the primarily GigaPans which facilitate student learning, exploration, and ability to make connections by exploring smaller scale features of the primary layer. A third layer of online material, GigaPans of thin sections of hand samples (from secondary layers), and curriculum based on the GigaPans was then created to assist students in evaluating proposed hypotheses on the primary layers' geological origin. GigaPan cirriculum was utilized in introductory

  8. Exploring Counseling Services and Their Impact on Female, Underrepresented Minority Community College Students in Science, Technology, Engineering, and Math: A Qualitative Study (United States)

    Strother, Elizabeth

    The economic future of the United States depends on developing a workforce of professionals in science, technology, engineering and mathematics (Adkins, 2012; Mokter Hossain & Robinson, 2012). In California, the college population is increasingly female and underrepresented minority, a population that has historically chosen to study majors other than STEM. In California, community colleges provide a major inroad for students seeking to further their education in one of the many universities in the state. The recent passage of Senate Bill 1456 and the Student Success and Support Program mandate increased counseling services for all California community college students (California Community College Chancellors Office, 2014). This dissertation is designed to explore the perceptions of female, underrepresented minority college students who are majoring in an area of science, technology, engineering and math, as they relate to community college counseling services. Specifically, it aims to understand what counseling services are most effective, and what community college counselors can do to increase the level of interest in STEM careers in this population. This is a qualitative study. Eight participants were interviewed for the case study, all of whom are current or former community college students who have declared a major in a STEM discipline. The semi-structured interviews were designed to help understand what community college counselors can do to better serve this population, and to encourage more students to pursue STEM majors and careers. Through the interviews, themes emerged to explain what counseling services are the most helpful. Successful STEM students benefited from counselors who showed empathy and support. Counselors who understood the intricacies of educational planning for STEM majors were considered the most efficacious. Counselors who could connect students with enrichment activities, such as internships, were highly valued, as were counseling

  13. The Influence of the Educational Reform in Slovakia on Educational Contents and Technology in Pre-College Economic Education

    Directory of Open Access Journals (Sweden)

    Jaromír Novák


    Full Text Available Purpose – the Slovak educational reform caused many changes in the Slovak school system. In the article, the author analyzes the impact it had on the educational contents and technology in pre-college economic education as part of general education.Design/methodology/approach – curriculum documents analysis, literature review, opinion survey (questionnaire, qualitative research (interview.Findings – he reform resulted in more teaching time as well as more practical orientation of economic education in general education in primary and secondary schools. However, what is still missing in the contents of this branch of economic education is more space for entrepreneurship education that would help to develop entrepreneurial skills necessary for the students to become more economically independent after they leave school. Although the reform gave schools more freedom in creating their school educational programs, it did not provide them with extra funds to finance the necessary modernization of the educational technologies they use. The differences in the use of modern ICT between different schools are thus attributable to other factors, unrelated to the educational reform process.Research limitations/implications – in the analysis of the contents of pre-college economic education, the author focused on the educational standards set by the state educational program, which must be respected by all schools in Slovakia. Although the reality of economic education in general education differs among schools (some schools created even several separated economic courses compulsory for all their students, others offer only a minimum required by the state educational program infused in a compulsory social studies course, it might also be interesting to analyze a sample of school educational programs for comparison and a more in-depth analysis.Originality/value – the article presents the findings of the genuine research.Research type: research paper.

  14. Exploration of offering photoelectric experimental general elective courses for college students of science and technology (United States)

    Tao, Shen; Sun, Binchao


    The necessity of offering photoelectric experiment general elective courses, such as the experiments of modern optical and innovational photoelectric design for non optic-electric's science and engineering students were discussed based on the analysis of the status quo and problems in experimental general elective course in science and engineering colleges of our country. And the characters of photoelectric disciplines, the goal of science and engineering quality-oriented education and the reform of science education at home and abroad were also considered. The instructional objectives, contents and characteristics of the courses were investigated. The specific methods, the CDIO (conceive, design, implement and operate) mode in the general courses has been proposed; the experiences and practical effects of offering these courses were concluded.

  15. Lecture capture: enhancing learning through technology at the Kent State University College of Podiatric Medicine. (United States)

    DiBacco, Priscilla M; Hetherington, Vincent J; Putman, David


    The intent of this research was to evaluate the Mediasite lecture capture system at the Kent State University College of Podiatric Medicine (formerly the Ohio College of Podiatric Medicine) to determine the acceptance, use and benefits to both students and faculty and to identify any concerns, limitations, and suggestions for expansion. There is extreme debate on the effect of lecture capture on student attendance included in the research. Two surveys were compiled, one each for students and faculty. These were distributed by email to the entire student body and all full-time and part-time faculty. Responses were voluntary. The questions sought to identify the priorities of the participant, reasons for viewing lectures compiled by course, to assess any effect on class attendance and to evaluate the ease and use of the technical function. There was also a section for subjective responses and suggestions. The tabulations proved a very high use of the program with the most important reason being to prepare for exams. The question of class attendance is still open to interpretation. Technically, the Mediasite system was ranked easy to use by both groups. The results of this survey confirm the concept of lecture capture as an integral segment of advanced education. Though this system should not replace class attendance, it is a vital supplement to course work and study. By reviewing all of the components of the survey those who may have concerns on its effectiveness are also aware of the advantages. The results of this study met all the objectives to evaluate use and obtain viewpoints to improve and expand the program.

  16. Empirical modeling of information communication technology usage behaviour among business education teachers in tertiary colleges of a developing country

    Directory of Open Access Journals (Sweden)

    Dauda Dansarki Isiyaku


    Full Text Available This study has empirically tested the fitness of a structural model in explaining the influence of two exogenous variables (perceived enjoyment and attitude towards ICTs on two endogenous variables (behavioural intention and teachers' Information Communication Technology (ICT usage behavior, based on the proposition of Technology Acceptance Model (Davis, 1989a. The sample was 212 teachers from Business Education faculties of 13 tertiary colleges in the northwestern region of Nigeria. As one of the major developing countries in Africa, Nigeria has invested a lot of resources in ICTs for the past several years to ensure the appropriate uptake and integration of technology across the important sectors of the country's economy, especially the education sector. Unfortunately, the country's standard of ICT adoption has remained low for many years. Congruently, its educational sector has remained incapacitated by lack of adequate ICT facilities and lack of skilled ICT-manpower, with school teachers using obsolete tools in the classroom, and some of them buying and using ICTs out of their own volition. Teachers' use of ICTs in tertiary schools' has remained poor in Nigeria, and research initiatives on ICT usage behaviour are rare and predominantly descriptive in nature. Past studies have dwelt on investigating the influence of physical infrastructural facilities on teachers' use of technology in the classroom. The current study has investigated the influence of teachers' perceptive beliefs, attitudes and intentions on their technology usage behaviour, using Structural Equation Modeling (SEM. Findings have shown that teachers' perceived enjoyment of ICTs influences their ICT usage behaviour in the classroom (β = .281, p < .05; teachers' perceived enjoyment of ICTs influences their intention to use ICTs (β = .740, p < .001; teachers' ICT attitude influences their intention to use ICTs (β = .122, p < .05; teachers' ICT attitude influences their ICT

  13. Environmental restoration technology programs at Mesa State College: A strategic look at manpower needs

    International Nuclear Information System (INIS)

    Harrison, R.J.; Emilia, D.A.


    The environmental cleanup of Department of Energy (DOE) sites within the next 30 years requires strategic planning to ensure adequate manpower is available when needed. Manpower needs projections within DOE have been based on analyses of current industry trends that indicate a substantial shortage of scientists and engineers. This paper explores the idea that the manpower requirements of DOE's environmental restoration program are not yet fully realized by most sites, which are currently in the predecisional work phase. Experience at the Grand Junction Projects Office (GJPO), which has had environmental restoration as it primary mission for about 10 years, shows that in the postdecisional phases the manpower need for scientists and engineers decreases while the manpower need for technologists in technical, management, and support roles increases. The GJPO, with Mesa State College in Grand Junction, Colorado, has developed an Environmental Restoration Associate degree program based on a strategic look at its manpower needs. This program receives start-up funding from DOE and has received donations in the million dollar range from various industry and state government partners

  14. Mobile Health Technology Using a Wearable Sensorband for Female College Students With Problem Drinking: An Acceptability and Feasibility Study. (United States)

    Leonard, Noelle Regina; Silverman, Michelle; Sherpa, Dawa Phuti; Naegle, Madeline A; Kim, Hyorim; Coffman, Donna L; Ferdschneider, Marcy


    An increasing number of mobile app interventions have been developed for problem drinking among college students; however, few studies have examined the integration of a mobile app with continuous physiological monitoring and alerting of affective states related to drinking behaviors. The aim of this paper was to evaluate the acceptability and feasibility of Mind the Moment (MtM), a theoretically based intervention for female college students with problem drinking that combines brief, in-person counseling with ecological momentary intervention (EMI) on a mobile app integrated with a wearable sensorband. We recruited 10 non-treatment seeking, female undergraduates from a university health clinic who scored a 3 or higher on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) to participate in this pilot study. Study activities involved an in-person baseline intake and 1 follow-up assessment, 2 in-person alcohol brief intervention counseling sessions, and use of MtM technology components (sensorband and EMI on a mobile app) for approximately 3-4 weeks. The intervention used motivational interviewing (MI) and cognitive behavioral therapy (CBT) strategies for reducing risks associated with drinking. We used both qualitative and quantitative assessments to measure acceptability of the intervention and feasibility of delivery. Use patterns of the sensorband and mobile app were also collected. Quantitative and qualitative data indicated high levels of acceptability for the MtM intervention. Altogether, participants made reports on the app on 26.7% (78/292) the days the technology was available to them and completed a total of 325 reports with wide variation between participants. Qualitative findings indicated that sensorband-elicited alerts promoted an increase in awareness of thoughts, feelings, and behaviors related to current environmental stressors and drinking behaviors in theoretically meaningful ways. Specific challenges related to functionality and

    Since 2004, Nara National College of Technology has been conducting “The Super Science Teacher Delivery Lecture Project”, in which the staff of our college visit elementary or junior high schools to provide special classes on science, technology or other subjects. This project was adopted as part of the Support Program for Contemporary Educational Needs by the Ministry of Education, Culture, Sports, Science and Technology. To provide education on design skills for students in the advanced mechanical engineering course and advanced electronic and information engineering course of the faculty of advanced engineering of our college, Problem Based Learning (PBL) has been conducted with the cooperation of the Super Science Teacher Delivery Lecture Project. In the PBL, students developed the teaching materials and experiments for science and technology lessons of elementary or junior high school students. In addition, the design skills of the students were evaluated by the reports on design skills, the demonstration of the delivery lecture and the records of the their efforts. From the results of the student questionnaire on this PBL, it is clear that most of the students understood “what are the design skills?” and acquired design skills.

  17. Remotely controlled repair of piping at Douglas Point

    International Nuclear Information System (INIS)

    Conrath, J.J.


    The 200 MWe Douglas Point Nuclear Generating Station which started operation in 1966 was Canada's first commercial nuclear power plant. In 1977, after 11 years of operation, leakage of heavy water was detected and traced to the Moderator Piping System (pipe sizes 19 mm to 76 mm) located in a vault below the reactor where the radiation fields during shutdown ranged up to 5000 R/Hr. Inspection using remotely operated TV cameras showed that a 'U' bolt clamp support had worn through the wall of one pipe and resulted in the leakage and also that wear was occurring on other pipes. An extensive repair plan was subsequently undertaken in the form of a joint venture of the designer-owner Atomic Energy of Canada Limited, and the builder-operator, Ontario Hydro. This paper describes the equipment and procedures used in remotely controlled repairs at Douglas Point

    Spera, D.A. (National Aeronautics and Space Administration, Cleveland, OH (USA). Lewis Research Center); Esgar, J.B. (Sverdrup Technology, Inc., Cleveland, OH (USA)); Gougeon, M.; Zuteck, M.D. (Gougeon Bros., Bay City, MI (USA))


    This publication contains a compilation of static and fatigue and strength data for laminated-wood material made from Douglas fir and epoxy. Results of tests conducted by several organizations are correlated to provide insight into the effects of variables such as moisture, size, lamina-to-lamina joint design, wood veneer grade, and the ratio of cyclic stress to steady stress during fatigue testing. These test data were originally obtained during development of wood rotor blades for large-scale wind turbines of the horizontal-axis (propeller) configuration. Most of the strength property data in this compilation are not found in the published literature. Test sections ranged from round cylinders 2.25 in. in diameter to rectangular slabs 6 in. by 24 in. in cross section and approximately 30 ft long. All specimens were made from Douglas fir veneers 0.10 in. thick, bonded together with the WEST epoxy system developed for fabrication and repair of wood boats. Loading was usually parallel to the grain. Size effects (reduction in strength with increase in test volume) are observed in some of the test data, and a simple mathematical model is presented that includes the probability of failure. General characteristics of the wood/epoxy laminate are discussed, including features that make it useful for a wide variety of applications. 9 refs.

  8. Minimal Liouville gravity correlation numbers from Douglas string equation

    International Nuclear Information System (INIS)

    Belavin, Alexander; Dubrovin, Boris; Mukhametzhanov, Baur


    We continue the study of (q,p) Minimal Liouville Gravity with the help of Douglas string equation. We generalize the results of, where Lee-Yang series (2,2s+1) was studied, to (3,3s+p 0 ) Minimal Liouville Gravity, where p 0 =1,2. We demonstrate that there exist such coordinates τ m,n on the space of the perturbed Minimal Liouville Gravity theories, in which the partition function of the theory is determined by the Douglas string equation. The coordinates τ m,n are related in a non-linear fashion to the natural coupling constants λ m,n of the perturbations of Minimal Lioville Gravity by the physical operators O m,n . We find this relation from the requirement that the correlation numbers in Minimal Liouville Gravity must satisfy the conformal and fusion selection rules. After fixing this relation we compute three- and four-point correlation numbers when they are not zero. The results are in agreement with the direct calculations in Minimal Liouville Gravity available in the literature

  14. Technology-based interventions for tobacco and other drug use in university and college students: a systematic review and meta-analysis. (United States)

    Gulliver, Amelia; Farrer, Louise; Chan, Jade K Y; Tait, Robert J; Bennett, Kylie; Calear, Alison L; Griffiths, Kathleen M


    University students have high levels of tobacco and other drug use, yet they are unlikely to seek traditional care. Technology-based interventions are highly relevant to this population. This paper comprises a systematic review and meta-analysis of published randomized trials of technology-based interventions evaluated in a tertiary (university/college) setting for tobacco and other drug use (excluding alcohol). It extends previous reviews by using a broad definition of technology. PubMed, PsycInfo, and the Cochrane databases were searched using keywords, phrases, and MeSH terms. Retrieved abstracts (n = 627) were double screened and coded. Included studies met the following criteria: (1) the study was a randomized trial or a randomized controlled trial (RCT); (2) the sample was composed of students attending a tertiary (e.g., university, college) institution; (3) the intervention was either delivered by or accessed using a technological device or process (e.g., computer/internet, telephone, mobile short message services [SMS]); (4) the age range or mean of the sample was between 18 and 25 years; and (5) the intervention was designed to alter a drug use outcome relating to tobacco or other drugs (excluding alcohol). A total of 12 papers met inclusion criteria for the current review. The majority of included papers examined tobacco use (n = 9; 75%), two studies targeted marijuana use (17%); and one targeted stress, marijuana, alcohol, and tobacco use. A quantitative meta-analysis was conducted on the tobacco use studies using an abstinence outcome measure (n = 6), demonstrating that the interventions increased the rate of abstinence by 1.5 times that of controls (Risk Ratio [RR] = 1.54; 95% Confidence Interval [CI] = 1.20-1.98). Across all 12 studies, a total of 20 technology-based interventions were reviewed. A range of technology was employed in the interventions, including stand-alone computer programs (n = 10), internet (n = 5), telephone (n = 3), and mobile SMS

  15. The Y Generation Myth: Evidences Based on the Causality Relations Among Age, Diffusion and Adoption of Technology of College Students of São Paulo State

    Directory of Open Access Journals (Sweden)

    Marcelo Gabriel


    Full Text Available The objective of this research was to assess whether college students, classified as Digital Natives and Digital Immigrants, show different behavioral styles and adoption profiles in relation to technology. To do so three measurement scales (Technological Origin - OTE, Adoption Profile - PAD and Innovator Behavioral Style - ECI were used and to identify the causal relationships among concepts, attitudes and processes of technology adoption among students. The data analysis choice was based on structural equation model (SEM variance based approach or partial least squares (PLS-SEM using the SmartPLS 2.0 software. The general model was tested, comprised by the constructs of the three scales and then a variable which characterizes the respondent’s generation was introduced as moderator. As a result it is possible to state that for the concepts of Digital Native and Digital Immigrant are lacking empirical foundations, simply serving as a rhetorical figure, of easy acceptance and assimilation, but unable to substantiate the existence of a phenomenon or generations effect on the process of diffusion and technology adoption, unlike what is commonly proposed in the literature.

  20. Science Self-Efficacy and Innovative Behavior (IB) in Nigerian College Students Enrolled in Science, Technology, Engineering, and Mathematics (STEM) Programs (United States)

    Okonkwo, Charles

    This study will explore how science self-efficacy among college students in science, technology, engineering, and mathematics (STEM) fields in Nigeria predicts their innovation. Several reports on African development argue that science, technology and innovation underpin targets for dramatically reducing poverty in its many dimensions---income poverty, hunger, disease, exclusion, lack of infrastructure and shelter---while promoting gender equality, education, health, and environmental sustainability (UN Millennium Project, 2005). If African countries in general, including Nigeria, are to move from the exploitation of natural resources to technological innovation as the foundation for development, stakeholders in these countries must encourage development of individual ability to innovate products, services and work processes in crucial organizations (DeJong & DenHartog, 2010). The common denominator in the scientific and technological development of any country or organization is the individuals that make up these entities. An individual's engagement is the foundation for group motivation, innovation and improvement. These ideas inform the purpose of this study: to investigate how science self-efficacy among college students in various engineering fields in Nigeria predicts self-reported innovative behavior (IB), also referred to as Innovative Work Behavior (IWB). IB involves initiating new and useful ideas, processes, products or procedures, as well as the process of implementing these ideas (Farr & Ford, 1990; Scott & Bruce, 1994). The general findings of this study align with the dictates of social cognitive theory. Specifically, research indicates self-efficacy has the most predictive power for performance when it is measured at a level specific to the expected task (Bandura, 1997; Pajares, 1996). The findings from the hierarchical multiple regressions confirm that individuals' perceived science efficacy plays an important role in their perceived self

  4. Identification of varieties and gene flow in Douglas fir exemplified in artificially established stands in Germany

    Directory of Open Access Journals (Sweden)

    Barbara Fussi


    Full Text Available Douglas-fir [Pseudotsuga menziesii (Mirb. Franco] is an economically valuable non-native tree species in Germany and is considered very promising in view of global climate change. Therefore, the genetic characterization of Douglas-fir populations and seed stands in Germany is essential. We studied coastal and interior Douglas-fir varieties, both present in Germany, by using eleven isoenzyme and four microsatellite loci. By analyzing eight reference populations of known origin we were able to identify the two varieties on the population level using Bayesian and distance based methods. Seven populations present in Bavaria were then successfully assigned to one of the two varieties. Within varieties we found stronger grouping within the interior variety than within the coastal one. Despite lower differences within coastal Douglas-fir we have first indications for the origin of two populations. For two Bavarian populations, natural regeneration was included and genetic data revealed no significant genetic difference between adults and offspring. The parentage analysis for one of the studied stands revealed that a large proportion of adults took part in the reproduction, but some trees were more successful than others in transferring their genes to the next generation. Our study was able to improve variety identification of Douglas-fir using isoenzyme markers and nuclear microsatellites and study reproductive patterns, both are important issues for the management of Douglas-fir stands in Bavaria.

  5. Analysis of solar thermophotovoltaic test data from experiments performed at McDonnell Douglas

    Stone, K.W.; Kusek, S.M.; Drubka, R.E. [McDonnell Douglas, 5301 Bolsa Avenue, Huntington Beach, California 92647 (United States); Fay, T.D. [21911 Bacalar, Mission Viejo, California 92692 (United States)


    Solar thermophotovoltaic power systems offer potentially high system efficiency for solar energy to electrical energy conversion and attractive system advantages. McDonnell Douglas Corporation (MDC) has been investigating this technology for both space and terrestrial applications for several years. A testbed prototype was designed, built, and tested on a 90 kW{sub t} dish concentrator at the MDA solar test facility. Twelve experiments were conducted with absorber temperatures in excess of 1300 {degree}C being achieved using only a fraction of the reflected power from the 90 kW{sub t} dish concentrator. This paper discusses the solar thermophotovoltaic testbed prototype unit, test data, and presents an analysis of the unit`s performance. A combination of analytical analysis and test data is used to obtain an understanding of the system and subsystem performance. The preliminary results of these tests and analysis indicate a solar thermophotovoltaic power system can achieve high system performance. Furthermore, system demonstrations are possible utilizing a combination of current off-the-shelf hardware components and components currently being tested in laboratories. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.

  6. Navigating the science, technology, engineering, and mathematics pipeline: How social capital impacts the educational attainment of college-bound female students (United States)

    Lee, Rebecca Elizabeth

    Despite the proliferation of women in higher education and the workforce, they have yet to achieve parity with men in many of the science, technology, engineering, and math (STEM) majors and careers. The gap is even greater in the representation of women from lower socioeconomic backgrounds. This study examined pre-college intervention strategies provided by the University of Southern California's Math, Engineering, Science Achievement (MESA) program, as well as the relationships and experiences that contributed to the success of underrepresented female high school students in the STEM pipeline. A social capital framework provided the backdrop to the study. This qualitative study takes an ethnographic approach, incorporating 11 interviews, 42 hours of observation, and document analysis to address the research questions: How does involvement in the MESA program impact female students' decisions to pursue a mathematics or science major in college? What is the role of significant others in supporting and encouraging student success? The findings revealed a continuous cycle of support for these students. The cycle started in the home environment, where parents were integral in the early influence on the students' decisions to pursue higher education. Relationships with teachers, counselors, and peers provided critical networks of support in helping these students to achieve their academic goals. Participation in the MESA program empowered the students and provided additional connections to knowledge-based resources. This study highlights the interplay among family, school, and the MESA program in the overall support of underrepresented female students in the STEM pipeline.

  9. Exploring assistive technology use to support cognition in college students with histories of mild traumatic brain injury. (United States)

    Brown, Jessica; Wollersheim, Madeline


    College students with mild traumatic brain injury (mTBI) may experience chronic cognitive deficits necessitating use of external supports for daily task completion. The purpose of this study was to explore cognitive support system selection and use by students with histories of mTBI when completing novel prospective memory tasks. We implemented a multiple case study, sequential explanatory mixed-methods design with three participants. Participants completed four experimental phases: (1) background history collection, cognitive assessment completion, pre-trial interview, and selection of two external supports for trial phase use; (2) trial Phase 1 (i.e., 10-days); (3) trial Phase 2 (i.e., 10 days); and (4) post-trial exit interview. We examined participants' support type and characteristic preferences and evaluated task execution accuracy when implementing differing supports. Participants expressed both collective and unique cognitive aid preferences before trial completion. Trial phase results revealed that task completion accuracy did not alter substantially between trials; however, personal preferences and perceived usefulness of trialled cognitive aid systems appeared to impact support implementation and effectiveness. Themes emerged from post-trial interview relating to the (a) necessity for differing functions of individual systems and (b) importance of trialling devices prior to selection. Results emphasize the necessity of person-centred approaches to treatment due to the variability of performance accuracy and system preferences. The cognitive aid selection and implementation intervention protocol piloted in this study appears beneficial for understanding unique strengths and challenges for college students following mTBI and may be useful for clinicians working with individuals with mTBI. Implications for rehabilitation College-aged students with mild traumatic brain injury report unique preferences for no- and high-tech cognitive aids; however, similar

    Energy Technology Data Exchange (ETDEWEB)

    Akamatsu, K.; Kanemura, M.; Amako, K.


    Wind conditions, such as average wind velocity for 10 minutes, maximum instantaneous wind velocity and wind directions, are measured by the anemometer and anemoscope installed 3m above the roof of the Kobe City College of Technology`s Information Processing Center building, to collect the data necessary to validate possibility of wind power generation, if the wind system is installed in the college site. Monthly availability of power is estimated from the output power characteristics curve for a generator having a rated capacity of 200W and wind velocity data collected for 9 months. It will generate power of only 144kWh, even when operated to give the rated output, or approximately 8.5kWh at the highest in a month, because of availability of wind power limited to around 30% of the total as estimated from the relative frequency distribution. It is therefore desirable to install a number of units having a rated capacity of 200W or else a smaller number of larger units. Assuming that days that give the highest output for 24 hours last 1 month, a power of 54.3kWh will be generated. It is estimated, based on these results, that a hybrid unit, in which a wind power generator installed at a high place is combined with a solar unit, can provide power required for nighttime lighting, if a wind power unit having a rated capacity of 2kW is field-controlled under an optimum condition. 13 figs., 3 tabs.

  16. Science-Technology-Society literacy in college non-majors biology: Comparing problem/case studies based learning and traditional expository methods of instruction (United States)

    Peters, John S.

    This study used a multiple response model (MRM) on selected items from the Views on Science-Technology-Society (VOSTS) survey to examine science-technology-society (STS) literacy among college non-science majors' taught using Problem/Case Studies Based Learning (PBL/CSBL) and traditional expository methods of instruction. An initial pilot investigation of 15 VOSTS items produced a valid and reliable scoring model which can be used to quantitatively assess student literacy on a variety of STS topics deemed important for informed civic engagement in science related social and environmental issues. The new scoring model allows for the use of parametric inferential statistics to test hypotheses about factors influencing STS literacy. The follow-up cross-institutional study comparing teaching methods employed Hierarchical Linear Modeling (HLM) to model the efficiency and equitability of instructional methods on STS literacy. A cluster analysis was also used to compare pre and post course patterns of student views on the set of positions expressed within VOSTS items. HLM analysis revealed significantly higher instructional efficiency in the PBL/CSBL study group for 4 of the 35 STS attitude indices (characterization of media vs. school science; tentativeness of scientific models; cultural influences on scientific research), and more equitable effects of traditional instruction on one attitude index (interdependence of science and technology). Cluster analysis revealed generally stable patterns of pre to post course views across study groups, but also revealed possible teaching method effects on the relationship between the views expressed within VOSTS items with respect to (1) interdependency of science and technology; (2) anti-technology; (3) socioscientific decision-making; (4) scientific/technological solutions to environmental problems; (5) usefulness of school vs. media characterizations of science; (6) social constructivist vs. objectivist views of theories; (7

  20. Carbon Sequestration in Soils Affected by Douglas Fir Reforestation in Apennines (Northern Italy

    Directory of Open Access Journals (Sweden)

    Giampaolo Di Biase


    Full Text Available Douglas fir reforestation plays an important role in Italian forest because no indigenous conifer has similar characteristics of productivity and timber quality. Few studies on physicochemical properties of soils under Douglas fire are noticeable. The aim of this work is to evaluate the organic C stock into soils under Douglas fir plantation in different selected areas. The areas of study are located in the North Apennine (Italy; Corno alle Scale (COR, Vallombrosa (VAL, Mulino Mengoni (MEN, respectively are chosen for the presence of Douglas fir reforestation of 60 years old. Two soil profiles for each area have been open and described. The pH value decreased along the profile depth. The organic C amount in organic layers was higher in Val and Men pedons than that determined in COR one. Higher amount of organic C were detected in organo-mineral horizons of Co pedons, highlighting a rapid turnover of soil organic matter. The C stock calculated in the first 30 cm of soil showed that the higher C amount is stored in highest altitudes profiles (COR6 and VAL6 than the other. The soil are classified as Lithic Dystrudepts in the highest altitudes (COR 6, 7 and VAL 6, 7, respectively while as Humic Dystrudepts in MEN (4 and 5 pedons. We conclude that no dangerous effects on soil quality of Douglas fir were investigated and they seem to be similar to those of native tree species, even if other different aspects should be investigated.

  1. An Allometric Algorithm for Fractal-Based Cobb-Douglas Function of Geographical Systems

    Directory of Open Access Journals (Sweden)

    Hongyu Luo


    Full Text Available The generalized Cobb-Douglas production function has been derived from a general input-output relation based on fractality assumptions. It was proved to be a useful self-affine model for geographical analysis. However, the ordinary least square calculation is always an ineffectual method for the Cobb-Douglas modeling because of the multicollinearity in the logarithmic linear regression. In this paper, a novel approach is proposed to build the geographical Cobb-Douglas models. Combining the concept of allometric scaling with the linear regression technique, we obtain a simple algorithm that can be employed to estimate the parameters of the Cobb-Douglas function. As a case, the algorithm and models are applied to the public transportation of China’s cities, and the results validate the allometric algorithm. A conclusion can be drawn that the allometric analysis is an effective way of modeling geographical systems with the general Cobb-Douglas function. This study is significant for integrating the notions of allometry, fractals, and scaling into a new framework to form a quantitative methodology of spatial analysis.

  3. The Campus Demotechnic Index: A comparison of technological energy consumption at U.S. colleges and universities (United States)

    Vance, Leisha Ann

    The Campus Demotechnic Index (CDI) is a normalized metric developed to provide universities with a method for tracking progress toward or retreat from sustainability in their energy consumption. The CDI is modified after the Demotechnic Index of Mata et al. (1994). CDI values assess the total campus energy consumed against the total energy required to meet the campus population's basal metabolism. Like the D-Index, the CDI is thus a measure of the scalar quantity of energy consumed in excess of the quantity of energy required for simple survival on a per capita basis. For this research, data were collected from an on-line survey designed for U.S. colleges and universities, which requested information related to campus demographics and campus built and mobile environmental energy consumption. Data were requested for the years of 2000 to 2005. Wilcoxon signed rank test analyses were conducted to determine if CDI values significantly increased over time. ANOVAs, GLMs, correlations and regressions were conducted to determine if climate and campus size significantly influenced CDI. ANOVAs, correlations and regressions were conducted to determine the effect of acreage on mobile fuel consumption and to ascertain whether differing proportions between the built and mobile environments significantly influenced CDI values. Correlations and regressions were carried out to which variables best predicted CDI, and cluster analyses were conducted to find out if any significant groups existed based on CDI values, fossil fuel consumption and population per square foot. The knowledge gained from results of these analyses not only provides a depiction of campus energy consumption, but also puts campus energy consumption into context in that CDI scores allow peer institutional comparisons. Awareness of factors that contribute to campus energy use (and CDI ranks) could also facilitate prioritization of sustainability-related issues, as well as the design and establishment of sustainable

  4. Mathematical learning instruction and teacher motivation factors affecting science technology engineering and math (STEM) major choices in 4-year colleges and universities: Multilevel structural equation modeling (United States)

    Lee, Ahlam


    Using the Educational Longitudinal Study of 2002/06, this study examined the effects of the selected mathematical learning and teacher motivation factors on graduates' science, technology, engineering, and math (STEM) related major choices in 4-year colleges and universities, as mediated by math performance and math self-efficacy. Using multilevel structural equation modeling, I analyzed: (1) the association between mathematical learning instruction factors (i.e., computer, individual, and lecture-based learning activities in mathematics) and students' STEM major choices in 4-year colleges and universities as mediated by math performance and math self-efficacy and (2) the association between school factor, teacher motivation and students' STEM major choices in 4-year colleges and universities via mediators of math performance and math self-efficacy. The results revealed that among the selected learning experience factors, computer-based learning activities in math classrooms yielded the most positive effects on math self-efficacy, which significantly predicted the increase in the proportion of students' STEM major choice as mediated by math self-efficacy. Further, when controlling for base-year math Item Response Theory (IRT) scores, a positive relationship between individual-based learning activities in math classrooms and the first follow-up math IRT scores emerged, which related to the high proportion of students' STEM major choices. The results also indicated that individual and lecture-based learning activities in math yielded positive effects on math self-efficacy, which related to STEM major choice. Concerning between-school levels, teacher motivation yielded positive effects on the first follow up math IRT score, when controlling for base year IRT score. The results from this study inform educators, parents, and policy makers on how mathematics instruction can improve student math performance and encourage more students to prepare for STEM careers.

  13. Effect of stand edge on the natural regeneration of spruce, beech and Douglas-fir

    Directory of Open Access Journals (Sweden)

    Lumír Dobrovolný


    Full Text Available Our work aimed at studying the strategy of woody plants regeneration during the regeneration of a spruce stand with the admixture of beech and Douglas-fir by border cutting (NW-SE aspect on acidic sites of higher elevations in the Bohemian-Moravian Upland. Spruce is better adapted to bear shade than Douglas-fir. Nevertheless, in optimal light conditions up to a distance of ca. 35 m (about 16% DIFFSF from the stand edge, the Douglas-fir can put the spruce into danger as to height growth. By contrast to beech, the density of spruce is significantly higher within the distance of 45 m (about 15% DIFFSF from the stand edge but further on the situation would change to the benefit of beech. The density of Douglas-fir significantly dominates over beech within a distance of 35 m from the stand edge; from 55 m (less than 15% DIFFSF, the situation changes in favour of beech. Beech can survive in full shade deep in the stand core waiting for its opportunity to come. As compared to spruce and Douglas-fir, the height growth of beech was at all times significantly greater at a distance of 25 m from the stand edge. Converted to practical conditions, spruce and Douglas-fir with individually admixed beech seedlings showed good prosperity approximately up to a distance of one stand height from the edge. A mixture of spruce and beech did well at a greater distance but good prosperity at a distance of 2–3 stand heights was shown only by beech. Thus, border regeneration eliminates disadvantages of the climatic extremes of clear-cutting and specifics of shelterwood felling during which one – usually shade-tolerant tree species dominates in the natural regeneration (e.g. beech.

  14. Soil spore bank communities of ectomycorrhizal fungi in endangered Chinese Douglas-fir forests. (United States)

    Wen, Zhugui; Shi, Liang; Tang, Yangze; Hong, Lizhou; Xue, Jiawang; Xing, Jincheng; Chen, Yahua; Nara, Kazuhide


    Chinese Douglas-fir (Pseudotsuga sinensis) is an endangered Pinaceae species found in several isolated regions of China. Although soil spore banks of ectomycorrhizal (ECM) fungi can play an important role in seedling establishment after disturbance, such as in the well-known North American relative (Pseudotsuga menziesii), we have no information about soil spore bank communities in relict forests of Chinese Douglas-fir. We conducted bioassays of 73 soil samples collected from three Chinese Douglas-fir forests, using North American Douglas-fir as bait seedlings, and identified 19 species of ECM fungi. The observed spore bank communities were significantly different from those found in ECM fungi on the roots of resident trees at the same sites (p = 0.02). The levels of potassium (K), nitrogen (N), organic matter, and the pH of soil were the dominant factors shaping spore bank community structure. A new Rhizopogon species was the most dominant species in the spore banks. Specifically, at a site on Sanqing Mountain, 22 of the 57 surviving bioassay seedlings (representing 21 of the 23 soil samples) were colonized by this species. ECM fungal richness significantly affected the growth of bioassay seedlings (R 2  = 0.20, p = 0.007). Growth was significantly improved in seedlings colonized by Rhizopogon or Meliniomyces species compared with uncolonized seedlings. Considering its specificity to Chinese Douglas-fir, predominance in the soil spore banks, and positive effect on host growth, this new Rhizopogon species could play critical roles in seedling establishment and forest regeneration of endangered Chinese Douglas-fir.

  10. On Measurement of Efficiency of Cobb-Douglas Production Function with Additive and Multiplicative Errors

    Directory of Open Access Journals (Sweden)

    Md. Moyazzem Hossain


    Full Text Available In developing counties, efficiency of economic development has determined by the analysis of industrial production. An examination of the characteristic of industrial sector is an essential aspect of growth studies. The most of the developed countries are highly industrialized as they brief “The more industrialization, the more development”. For proper industrialization and industrial development we have to study industrial input-output relationship that leads to production analysis. For a number of reasons econometrician’s belief that industrial production is the most important component of economic development because, if domestic industrial production increases, GDP will increase, if elasticity of labor is higher, implement rates will increase and investment will increase if elasticity of capital is higher. In this regard, this paper should be helpful in suggesting the most suitable Cobb-Douglas production function to forecast the production process for some selected manufacturing industries of developing countries like Bangladesh. This paper choose the appropriate Cobb-Douglas function which gives optimal combination of inputs, that is, the combination that enables it to produce the desired level of output with minimum cost and hence with maximum profitability for some selected manufacturing industries of Bangladesh over the period 1978-79 to 2011-2012. The estimated results shows that the estimates of both capital and labor elasticity of Cobb-Douglas production function with additive errors are more efficient than those estimates of Cobb-Douglas production function with multiplicative errors.

  15. Douglas-Fir Seedlings Exhibit Metabolic Responses to Increased Temperature and Atmospheric Drought (United States)

    Jansen, Kirstin; Du, Baoguo; Kayler, Zachary; Siegwolf, Rolf; Ensminger, Ingo; Rennenberg, Heinz; Kammerer, Bernd; Jaeger, Carsten; Schaub, Marcus; Kreuzwieser, Jürgen; Gessler, Arthur


    In the future, periods of strongly increased temperature in concert with drought (heat waves) will have potentially detrimental effects on trees and forests in Central Europe. Norway spruce might be at risk in the future climate of Central Europe. However, Douglas-fir is often discussed as an alternative for the drought and heat sensitive Norway spruce, because some provenances are considered to be well adapted to drier and warmer conditions. In this study, we identified the physiological and growth responses of seedlings from two different Douglas-fir provenances to increased temperature and atmospheric drought during a period of 92 days. We analysed (i) plant biomass, (ii) carbon stable isotope composition as an indicator for time integrated intrinsic water use efficiency, (iii) apparent respiratory carbon isotope fractionation as well as (iv) the profile of polar low molecular metabolites. Plant biomass was only slightly affected by increased temperatures and atmospheric drought but the more negative apparent respiratory fractionation indicated a temperature-dependent decrease in the commitment of substrate to the tricarboxylic acid cycle. The metabolite profile revealed that the simulated heat wave induced a switch in stress protecting compounds from proline to polyols. We conclude that metabolic acclimation successfully contributes to maintain functioning and physiological activity in seedlings of both Douglas-fir provenances under conditions that are expected during heat waves (i.e. elevated temperatures and atmospheric drought). Douglas-fir might be a potentially important tree species for forestry in Central Europe under changing climatic conditions. PMID:25436455

  1. Using Real-Time Social Media Technologies to Monitor Levels of Perceived Stress and Emotional State in College Students: A Web-Based Questionnaire Study. (United States)

    Liu, Sam; Zhu, Miaoqi; Yu, Dong Jin; Rasin, Alexander; Young, Sean D


    College can be stressful for many freshmen as they cope with a variety of stressors. Excess stress can negatively affect both psychological and physical health. Thus, there is a need to find innovative and cost-effective strategies to help identify students experiencing high levels of stress to receive appropriate treatment. Social media use has been rapidly growing, and recent studies have reported that data from these technologies can be used for public health surveillance. Currently, no studies have examined whether Twitter data can be used to monitor stress level and emotional state among college students. The primary objective of our study was to investigate whether students' perceived levels of stress were associated with the sentiment and emotions of their tweets. The secondary objective was to explore whether students' emotional state was associated with the sentiment and emotions of their tweets. We recruited 181 first-year freshman students aged 18-20 years at University of California, Los Angeles. All participants were asked to complete a questionnaire that assessed their demographic characteristics, levels of stress, and emotional state for the last 7 days. All questionnaires were completed within a 48-hour period. All tweets posted by the participants from that week (November 2 to 8, 2015) were mined and manually categorized based on their sentiment (positive, negative, neutral) and emotion (anger, fear, love, happiness) expressed. Ordinal regressions were used to assess whether weekly levels of stress and emotional states were associated with the percentage of positive, neutral, negative, anger, fear, love, or happiness tweets. A total of 121 participants completed the survey and were included in our analysis. A total of 1879 tweets were analyzed. A higher level of weekly stress was significantly associated with a greater percentage of negative sentiment tweets (beta=1.7, SE 0.7; P=.02) and tweets containing emotions of fear (beta=2.4, SE 0.9; P=.01

  12. Benefit Opportunities for Integrated Surface and Airspace Departure Scheduling: A Study of Operations at Charlotte-Douglas International Airport (United States)

    Coppenbarger, Rich; Jung, Yoon; Kozon, Tom; Farrahi, Amir; Malik, Wakar; Lee, Hanbong; Chevalley, Eric; Kistler, Matt


    NASA is collaborating with the FAA and aviation industry to develop and demonstrate new capabilities that integrate arrival, departure, and surface air-traffic operations. The concept relies on trajectory-based departure scheduling and collaborative decision making to reduce delays and uncertainties in taxi and climb operations. The paper describes the concept and benefit mechanisms aimed at improving flight efficiency and predictability while maintaining or improving operational throughput. The potential impact of the technology is studied and discussed through a quantitative analysis of relevant shortfalls at the site identified for initial deployment and demonstration in 2017: Charlotte-Douglas International Airport. Results from trajectory analysis indicate substantial opportunity to reduce taxi delays for both departures and arrivals by metering departures at the gate in a manner that maximizes throughput while adhering to takeoff restrictions due mostly to airspace constraints. Substantial taxi-out delay reduction is shown for flights subject to departure restrictions stemming from traffic flow management initiatives. Opportunities to improve the predictability of taxi, takeoff, and climb operations are examined and their potential impact on airline scheduling decisions and air-traffic forecasting is discussed. In addition, the potential to improve throughput with departure scheduling that maximizes use of available runway and airspace capacity is analyzed.

  13. Increased Biomass of Nursery-Grown Douglas-Fir Seedlings upon Inoculation with Diazotrophic Endophytic Consortia

    Directory of Open Access Journals (Sweden)

    Zareen Khan


    Full Text Available Douglas-fir (Pseudotsuga menziesii seedlings are periodically challenged by biotic and abiotic stresses. The ability of endophytes to colonize the interior of plants could confer benefits to host plants that may play an important role in plant adaptation to environmental changes. In this greenhouse study, nursery-grown Douglas-fir seedlings were inoculated with diazotrophic endophytes previously isolated from poplar and willow trees and grown for fifteen months in nutrient-poor conditions. Inoculated seedlings had significant increases in biomass (48%, root length (13% and shoot height (16% compared to the control seedlings. Characterization of these endophytes for symbiotic traits in addition to nitrogen fixation revealed that they can also solubilize phosphate and produce siderophores. Colonization was observed through fluorescent microscopy in seedlings inoculated with gfp- and mkate-tagged strains. Inoculation with beneficial endophytes could prove to be valuable for increasing the production of planting stocks in forest nurseries.

  14. Some Characterizations of the Cobb-Douglas and CES Production Functions in Microeconomics

    Directory of Open Access Journals (Sweden)

    Xiaoshu Wang


    Full Text Available It is well known that the study of the shape and the properties of the production possibility frontier is a subject of great interest in economic analysis. Vîlcu (Vîlcu, 2011 proved that the generalized Cobb-Douglas production function has constant return to scale if and only if the corresponding hypersurface is developable. Later on, the authors A. D. Vîlcu and G. E. Vîlcu, 2011 extended this result to the case of CES production function. Both results establish an interesting link between some fundamental notions in the theory of production functions and the differential geometry of hypersurfaces in Euclidean spaces. In this paper, we give some characterizations of minimal generalized Cobb-Douglas and CES production hypersurfaces in Euclidean spaces.

  15. Increased water deficit decreases Douglas fir growth throughout western US forests (United States)

    Restaino, Christina M; Peterson, David L.; Littell, Jeremy


    Changes in tree growth rates can affect tree mortality and forest feedbacks to the global carbon cycle. As air temperature increases, evaporative demand also increases, increasing effective drought in forest ecosystems. Using a spatially comprehensive network of Douglas-fir (Pseudotsuga menziesii) chronologies from 122 locations that experience distinctly different climate in the western United States, we show that increased temperature decreases growth via vapor pressure deficit (VPD) across all latitudes. Under an ensemble of global circulation models, we project an increase in both the mean VPD associated with the lowest growth extremes and the probability of exceeding these VPD values. As temperature continues to increase in future decades, we can expect deficit-related stress to increase and consequently Douglas-fir growth to decrease throughout its US range.

  17. Glacial populations and postglacial migration of Douglas-fir based on fossil pollen and macrofossil evidence (United States)

    Gugger, Paul F.; Sugita, Shinya


    To understand how temperate forests might respond to future episodes of global warming, it is important to study the effects of large-scale climate change brought about by rapid postglacial warming. Compilations of fossil evidence have provided the best evidence of past plant range shifts, especially in eastern North America and Europe, and provide a context for interpreting new molecular datasets from modern forests. In western North America, however, such reviews have lagged even for common, widespread taxa. Here, we synthesize fossil evidence for Douglas-fir ( Pseudotsuga menziesii) from nearly 550 fossil pollen, sedimentary macrofossil, and packrat midden macrofossil sites to develop hypotheses about the species' late Quaternary history that can be tested with molecular phylogeographic studies. For both the coastal and interior varieties, we identified alternative hypotheses on the number of glacial populations and postglacial migration patterns that can be characterized as single-population versus multiple-population hypotheses. Coastal Douglas-fir may have been subdivided into two populations at the Last Glacial Maximum (LGM) and colonized British Columbia from populations in Washington and Oregon. Interior Douglas-fir could have been subdivided along major topographic barriers into at least three LGM populations and colonized British Columbia and Alberta from populations in northwest Wyoming and/or northeast Utah. For both varieties, we calculated migration rates lower than previous studies, which could have been as high as 100-220 m/yr if Douglas-fir reached its modern distribution 9000 cal yr BP, or as low as 50 m/yr if it reached its modern range at present. The elevational range of populations in California and the southern Rockies shifted upslope by 700-1000 m. If there were multiple LGM populations, these elevational shifts suggest that those populations did not contribute to the colonization of Canada. Our findings emphasize the possibility of low

  5. Fitting of full Cobb-Douglas and full VRTS cost frontiers by solving goal programming problem (United States)

    Venkateswarlu, B.; Mahaboob, B.; Subbarami Reddy, C.; Madhusudhana Rao, B.


    The present research article first defines two popular production functions viz, Cobb-Douglas and VRTS production frontiers and their dual cost functions and then derives their cost limited maximal outputs. This paper tells us that the cost limited maximal output is cost efficient. Here the one side goal programming problem is proposed by which the full Cobb-Douglas cost frontier, full VRTS frontier can be fitted. This paper includes the framing of goal programming by which stochastic cost frontier and stochastic VRTS frontiers are fitted. Hasan et al. [1] used a parameter approach Stochastic Frontier Approach (SFA) to examine the technical efficiency of the Malaysian domestic banks listed in the Kuala Lumpur stock Exchange (KLSE) market over the period 2005-2010.

  9. How Do Trees Know When to Flower? Predicting Reproductive Phenology of Douglas-fir with Changing Winter and Spring Temperatures (United States)

    Prevey, J.; St Clair, B.; Harrington, C.


    Flowering at the right time is one of the primary ways that plants are adapted to their environment. Trees that flower too early risk cold damage to vulnerable new tissues and those that flower too late miss peak resources or may mistime flowering to coincide with other trees, altering outcrossing rates and gene flow. Past observations indicate that temperature cues over winter and spring influence the timing of flowering in many tree species. Understanding these cues is important for predicting how flowering phenology of trees will change with a changing climate.We developed predictive models of flowering for Douglas-fir, an abundant and commercially important tree in the Pacific Northwest. We assembled over 10,000 flowering observations of trees from 11 sites across western Oregon and Washington. We modeled the dates of flowering using hourly temperature data; our models of flowering were adapted from previous models of vegetative budburst and height growth initiation developed for Douglas-fir. Preliminary results show that both chilling (cold) and forcing (warm) temperatures over winter and spring are important determinants of flowering time for Douglas-fir. This suggests that as spring temperatures warm in the future, Douglas-fir across the Pacific Northwest will flower earlier, unless plants experience insufficient chilling over winter, in which case it is possible that Douglas-fir may flower later than in the past, or not flower at all. At one site, Douglas-fir genotypes from different geographic regions flowered in the same order from year to year, indicating that both temperature and heredity influence flowering. Knowledge of the environmental and genetic cues that drive the timing of flowering can help predict how changes in temperature under various climate models could change flowering time across sites. These models may also indicate the geographic areas where future climate could enhance or reduce flowering of Douglas-fir in the future.

    At the beginning of the twentieth century, college algebra was taught differently than it is nowadays. There are many topics that are now part of calculus or analysis classes. Other topics are covered only in abstract form in a modern algebra class on field theory. Fine's College Algebra offers the reader a chance to learn the origins of a variety of topics taught in today's curriculum, while also learning valuable techniques that, in some cases, are almost forgotten. In the early 1900s, methods were often emphasized, rather than abstract principles. In this book, Fine includes detailed discus

  17. Subtidal circulation in a deep-silled fjord: Douglas Channel, British Columbia (United States)

    Wan, Di; Hannah, Charles G.; Foreman, Michael G. G.; Dosso, Stan


    Douglas Channel, a deep fjord on the west coast of British Columbia, Canada, is the main waterway in the fjord system that connects the town of Kitimat to Queen Charlotte Sound and Hecate Strait. A 200 m depth sill divides Douglas Channel into an outer and an inner basin. This study examines the low-frequency (from seasonal to meteorological bands) circulation in Douglas Channel from data collected at three moorings deployed during 2013-2015. The deep flows are dominated by a yearly renewal that takes place from May/June to early September. A dense bottom layer with a thickness of 100 m that cascades through the system at the speed of 0.1-0.2 m s-1, which is consistent with gravity currents. Estuarine flow dominates the circulation above the sill depth, and the observed landward net volume flux suggests that it is necessary to include the entire complex channel network to fully understand the estuarine circulation in the system. The influence of the wind forcing on the subtidal circulation is not only at the surface, but also at middepth. The along-channel wind dominates the surface current velocity fluctuations and the sea level response to the wind produces a velocity signal at 100-120 m in the counter-wind direction. Overall, the circulation in the seasonal and the meteorological bands is a mix of estuarine flow, direct wind-driven flow, and the barotropic and baroclinic responses to changes to the surface pressure gradient caused by the wind stress.

    Energy Technology Data Exchange (ETDEWEB)

    Rim, Chaiho, E-mail:; Zhang, Hong, E-mail:


    AGT conjecture connects Nekrasov instanton partition function of 4D quiver gauge theory with 2D Liouville conformal blocks. We re-investigate this connection using the central extension of spherical Hecke algebra in q-coordinate representation, q being the instanton expansion parameter. Based on AFLT basis together with intertwiners we construct gauge conformal state and demonstrate its equivalence to the Liouville conformal state, with careful attention to the proper scaling behavior of the state. Using the colliding limit of regular states, we obtain the formal expression of irregular conformal states corresponding to Argyres–Douglas theory, which involves summation of functions over Young diagrams.

    Naranjo, Ramon C.; Welborn, Toby L.; Rosen, Michael R.


    Residents of Carson Valley in Douglas County, Nevada, rely on groundwater from an alluvial aquifer for domestic use and agricultural irrigation. Since the 1970s, there has been a rapid increase in population in several parts of the valley that rely on domestic wells for drinking water and septic systems for treatment of household waste. As a result, the density of septic systems in the developed areas is greater than one septic system per 3 acres, and the majority of the domestic wells are shallow (screened within 250 feet of the land surface).

  4. Aliens and existential elevators: absurdity and its shadows in Douglas Adams’s Hitch hiker series

    Directory of Open Access Journals (Sweden)

    M.A. van der Colff


    Full Text Available According to twentieth-century existentialist philosophy, the universe as we know it is steeped in senselessness, and the only possible means of survival is the construction of subjective meaning. Douglas Adams’s fictional universe portrayed in his “Hitch hiker” series reflects the arbitrary nature of existence, and the characters dwelling in this narrative space are faced with two existential choices: the one is defiance in the face of senselessness, the other is bleak despair. This article explores the existential choices made by prominent characters in the “Hitch hiker” series. The article distinguishes between and analyses the Sisyphus characters and their polar opposites (or nihilist shadows in Douglas Adams’s “Hitch hiker” series. Adams’s characters, be they human, alien or sentient machine, all face the same existential choice: actuate individual meaning, or resort to despondency. Characters who choose the first option are regarded as Sisyphus figures, whereas characters who choose the latter are referred to as shadows or nihilist nemeses.

    Full Text Available The objective of the paper is to demonstrate the use of an unique extention of the Cobb-Douglas efficiency criteria for the measurement and quantification of labour productivity. The South African motor vehicle manufacturing industry is used as a case study. This paper adopts the hypothesis that one of the more important factors contributing to the spiralling unit cost in the motor vehicle industry is the sluggish level of labour productivity. The results of the measurements are indeed interesting and it substantiates the hypothesis that the low level of labour productivity does contribute significantly to the increasing unit cost of the industry.

  6. Tolerance to multiple climate stressors: A case study of Douglas-fir drought and cold hardiness (United States)

    Bansal, Sheel; Harrington, Constance A; St. Clair, John Bradley


    Summary: 1. Drought and freeze events are two of the most common forms of climate extremes which result in tree damage or death, and the frequency and intensity of both stressors may increase with climate change. Few studies have examined natural covariation in stress tolerance traits to cope with multiple stressors among wild plant populations. 2. We assessed the capacity of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii), an ecologically and economically important species in the northwestern USA, to tolerate both drought and cold stress on 35 populations grown in common gardens. We used principal components analysis to combine drought and cold hardiness trait data into generalized stress hardiness traits to model geographic variation in hardiness as a function of climate across the Douglas-fir range. 3. Drought and cold hardiness converged among populations along winter temperature gradients and diverged along summer precipitation gradients. Populations originating in regions with cold winters had relatively high tolerance to both drought and cold stress, which is likely due to overlapping adaptations for coping with winter desiccation. Populations from regions with dry summers had increased drought hardiness but reduced cold hardiness, suggesting a trade-off in tolerance mechanisms. 4. Our findings highlight the necessity to look beyond bivariate trait–climate relationships and instead consider multiple traits and climate variables to effectively model and manage for the impacts of climate change on widespread species.

  12. Tree-ring stable isotopes record the impact of a foliar fungal pathogen on CO(2) assimilation and growth in Douglas-fir. (United States)

    Saffell, Brandy J; Meinzer, Frederick C; Voelker, Steven L; Shaw, David C; Brooks, J Renée; Lachenbruch, Barbara; McKay, Jennifer


    Swiss needle cast (SNC) is a fungal disease of Douglas-fir (Pseudotsuga menziesii) that has recently become prevalent in coastal areas of the Pacific Northwest. We used growth measurements and stable isotopes of carbon and oxygen in tree-rings of Douglas-fir and a non-susceptible reference species (western hemlock, Tsuga heterophylla) to evaluate their use as proxies for variation in past SNC infection, particularly in relation to potential explanatory climate factors. We sampled trees from an Oregon site where a fungicide trial took place from 1996 to 2000, which enabled the comparison of stable isotope values between trees with and without disease. Carbon stable isotope discrimination (Δ(13)C) of treated Douglas-fir tree-rings was greater than that of untreated Douglas-fir tree-rings during the fungicide treatment period. Both annual growth and tree-ring Δ(13)C increased with treatment such that treated Douglas-fir had values similar to co-occurring western hemlock during the treatment period. There was no difference in the tree-ring oxygen stable isotope ratio between treated and untreated Douglas-fir. Tree-ring Δ(13)C of diseased Douglas-fir was negatively correlated with relative humidity during the two previous summers, consistent with increased leaf colonization by SNC under high humidity conditions that leads to greater disease severity in following years. © 2013 John Wiley & Sons Ltd.

  6. Silver fir and Douglas fir are more tolerant to extreme droughts than Norway spruce in south-western Germany. (United States)

    Vitali, Valentina; Büntgen, Ulf; Bauhus, Jürgen


    Improving our understanding of the potential of forest adaptation is an urgent task in the light of predicted climate change. Long-term alternatives for susceptible yet economically important tree species such as Norway spruce (Picea abies) are required, if the frequency and intensity of summer droughts will continue to increase. Although Silver fir (Abies alba) and Douglas fir (Pseudotsuga menziesii) have both been described as drought-tolerant species, our understanding of their growth responses to drought extremes is still limited. Here, we use a dendroecological approach to assess the resistance, resilience, and recovery of these important central Europe to conifer species the exceptional droughts in 1976 and 2003. A total of 270 trees per species were sampled in 18 managed mixed-species stands along an altitudinal gradient (400-1200 m a.s.l.) at the western slopes of the southern and central Black Forest in southwest Germany. While radial growth in all species responded similarly to the 1976 drought, Norway spruce was least resistant and resilient to the 2003 summer drought. Silver fir showed the overall highest resistance to drought, similarly to Douglas fir, which exhibited the widest growth rings. Silver fir trees from lower elevations were more drought prone than trees at higher elevations. Douglas fir and Norway spruce, however, revealed lower drought resilience at higher altitudes. Although the 1976 and 2003 drought extremes were quite different, Douglas fir maintained consistently the highest radial growth. Although our study did not examine population-level responses, it clearly indicates that Silver fir and Douglas fir are generally more resistant and resilient to previous drought extremes and are therefore suitable alternatives to Norway spruce; Silver fir more so at higher altitudes. Cultivating these species instead of Norway spruce will contribute to maintaining a high level of productivity across many Central European mountain forests under

  10. ACCF/AHA methodology for the development of quality measures for cardiovascular technology: a report of the American College of Cardiology Foundation/American Heart Association Task Force on Performance Measures. (United States)

    Consistent with the growing national focus on healthcare quality, the American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA) have taken a leadership role over the past decade in developing measures of the quality of cardiovascular care by convening a joint ACCF/AHA Task Force on Performance Measures. The Task Force is charged with identifying the clinical topics appropriate for the development of performance measures and with assembling writing committees composed of clinical and methodological experts in collaboration with appropriate subspecialty societies. The Task Force has also created methodology documents that offer guidance in the development of process, outcome, composite, and efficiency measures. Cardiovascular performance measures using existing ACCF/AHA methodology are based on Class I or Class III guidelines recommendations, usually with Level A evidence. These performance measures, based on evidence-based ACCF/AHA guidelines, remain the most rigorous quality measures for both internal quality improvement and public reporting. However, many of the tools for diagnosis and treatment of cardiovascular disease involve advanced technologies, such as cardiac imaging, for which there are often no underlying guideline documents. Because these technologies affect the quality of cardiovascular care and also have the potential to contribute to cardiovascular health expenditures, there is a need for more critical assessment of the use of technology, including the development of quality and performance measures in areas in which guideline recommendations are absent. The evaluation of quality in the use of cardiovascular technologies requires consideration of multiple parameters that differ from other healthcare processes. The present document describes methodology for development of 2 new classes of quality measures in these situations, appropriate use measures and structure/safety measures. Appropriate use measures are based on

  11. Fourier phase retrieval with a single mask by Douglas-Rachford algorithms. (United States)

    Chen, Pengwen; Fannjiang, Albert


    The Fourier-domain Douglas-Rachford (FDR) algorithm is analyzed for phase retrieval with a single random mask. Since the uniqueness of phase retrieval solution requires more than a single oversampled coded diffraction pattern, the extra information is imposed in either of the following forms: 1) the sector condition on the object; 2) another oversampled diffraction pattern, coded or uncoded. For both settings, the uniqueness of projected fixed point is proved and for setting 2) the local, geometric convergence is derived with a rate given by a spectral gap condition. Numerical experiments demonstrate global, power-law convergence of FDR from arbitrary initialization for both settings as well as for 3 or more coded diffraction patterns without oversampling. In practice, the geometric convergence can be recovered from the power-law regime by a simple projection trick, resulting in highly accurate reconstruction from generic initialization.

    We continue to use the Praesepe membership catalog presented in PaperII (Douglas+, 2014, J/ApJ/795/161), which includes 1130 cluster members with membership probabilities Pmem>=50% as calculated by Kraus & Hillenbrand (2007, J/AJ/134/2340) and 39 previously identified members too bright to be included by those authors in their catalog for the cluster. We assign these bright stars Pmem=100%. We also continue to use the photometry and stellar masses presented in Table 5 of Paper II. For most of our analysis, as in that work, we include only the 1099 stars with Pmem>=70%. K2 targeted Praesepe in its Campaign 5. We analyze the resulting long-cadence data for 794 Praesepe members. We present Prot for 677 K2 targets. Of these, 471 are new measurements. (3 data files).

  13. Irregular singularities in Liouville theory and Argyres-Douglas type gauge theories, I

    International Nuclear Information System (INIS)

    Gaiotto, D.; Teschner, J.


    Motivated by problems arising in the study of N=2 supersymmetric gauge theories we introduce and study irregular singularities in two-dimensional conformal field theory, here Liouville theory. Irregular singularities are associated to representations of the Virasoro algebra in which a subset of the annihilation part of the algebra act diagonally. In this paper we define natural bases for the space of conformal blocks in the presence of irregular singularities, describe how to calculate their series expansions, and how such conformal blocks can be constructed by some delicate limiting procedure from ordinary conformal blocks. This leads us to a proposal for the structure functions appearing in the decomposition of physical correlation functions with irregular singularities into conformal blocks. Taken together, we get a precise prediction for the partition functions of some Argyres-Douglas type theories on S 4 . (orig.)

  16. Carbon dioxide flux measurements from a coastal Douglas-fir forest floor

    International Nuclear Information System (INIS)

    Drewitt, G.B.


    This thesis examined the process that affects the exchange of carbon between the soil and the atmosphere with particular attention to the large amounts of carbon stored in soils in the form of decaying organic matter. This forest floor measuring study was conducted in 2000 at a micro-meteorological tower flux site in a coastal temperature Douglas-fir forest. The measuring study involved half hourly measurements of both carbon dioxide and below-ground carbon dioxide storage. Measurements were taken at 6 locations between April and December to include a large portion of the growing season. Eddy covariance (EC) measurements of carbon dioxide flux above the forest floor over a two month period in the summer and the autumn were compared with forest floor measurements. Below-ground carbon dioxide mixing ratios of soil air were measured at 6 depths between 0.02 to 1 m using gas diffusion probes and a syringe sampling method. Maximum carbon dioxide fluxes measured by the soil chambers varied by a factor of 3 and a high spatial variability in soil carbon dioxide flux was noted. Forest floor carbon dioxide fluxes measured by each of the chambers indicated different sensitivities to soil temperature. Hysteresis in the flux temperature relationship over the year was evident. Reliable below-canopy EC measurements of the forest floor carbon dioxide flux were difficult to obtain because of the every low wind speeds below the forest canopy. The amount of carbon dioxde present in the soil increased rapidly with depth near the surface but less rapidly deeper in the soil. It was suggested that approximately half of the carbon dioxide produced below-ground comes from between the soil surface and the first 0.15 m of depth. Carbon dioxide fluxes from the floor of a Douglas-fir forest were found to be large compared to other, less productive ecosystems

  14. Douglas fir (pseudotsuga menziesii) plantlets responses to as, PB, and sb-contaminated soils from former mines. (United States)

    Bonet, Amandine; Pascaud, Grégoire; Faugeron, Céline; Soubrand, Marilyne; Joussein, Emmanuel; Gloaguen, Vincent; Saladin, Gaëlle


    Phytoremediation of metalloids by conifers is not widely studied although they may be relevant for several contaminated sites, especially those located in cold areas and sometimes under dry climates. Here, seeds of Douglas fir were sown in greenhouse on three soils collected in two French former mines: a gold mine (soils L1 and L2) and a lead and silver mine (soil P). These soils are highly contaminated by Pb, As, and Sb at different concentrations. Plants were harvested after ten weeks. Growth parameters, primary metabolite content, and shoot and root ionomes were determined. Douglas firs grown on the soils L1 and P had a lower biomass than controls and a higher oxidation status whereas those grown on the soil L2 exhibited a more developed root system and only slight modifications of carbon and nitrogen nutrition. Based on trace element (TE) concentrations in shoots and roots and their translocation factor (TF), Douglas fir could be a relevant candidate for As phytoextraction (0.8 g. kg(-1) dry weight in shoots and a TF of 1.1) and may be used to phytostabilize Pb and Sb (8.8 g and 127 mg. kg(-1) in roots for Pb and Sb, respectively, and TF lower than 0.1).

    Reported in this paper is a photovoltaic power generation facility built in the yard of Nagaoka College of Technology. The purpose of this study is to find out if such a facility operates effectively in a heavy-snow region. A data logging system is also constructed. In a preliminary experiment, a 50W panel was installed, facing southwest at an inclination of 30degC, on the roof of the schoolhouse. A voltmeter, ammeter, and slide rheostat were used to perform necessary measurement. The panel temperature was approximately 50degC, and insolation was estimated at 70mW/cm{sup 2}. The data logging system is comprised of a personal computer, display, printer, etc. Using this system, voltage and current are measured with the load automatically adjusted, and the maximum power point is sought out and logged. In addition, insolation, ambient temperature, and panel temperature are logged. Data is logged every 10th minute and, when a day`s measurement is over, mean values are obtained for every hour and data is built for a power generation profile, all automatically. There is a plan for a wintertime power generation experiment. 3 refs., 5 figs.

  16. Enhancement of Carbon Sequestration in west coast Douglas-fir Forests with Nitrogen Fertilization (United States)

    Chen, B.; Jassal, R.; Black, A.; Brummer, C.; Spittlehouse, D.; Nesic, Z.


    Fertilization is one of the eligible management practices for C sequestering and hence reducing CO2 emissions under Article 3.4 of the Kyoto Protocol. In the coastal regions of British Columbia, which have very little nitrogen (N) deposition from pollution sources owing to their remote location, and soils deficient in N (Hanley et al., 1996), Douglas-fir stands respond to N fertilization (Brix, 1981; Fisher and Binkley, 2000; Chapin et al., 2002). However, a major concern with N fertilization is the potential loss from the soil surface of the highly potent greenhouse gas N2O, and little is known about such losses in N-fertilized forest soils. While it is necessary to determine and quantify the effects of N fertilization on stand C sequestration, it is also important to address environmental concerns by measuring N2O emissions to determine the net greenhouse gas (GHG) global warming potential (GWP). The GWP of N2O is 296 times (100-year time horizon) greater than that of CO2 (Ehhalt and Prather, 2001), yet there is little information on its net radiative forcing as a result of forest fertilization. We report two years of results on the effects of N fertilization in a chronosequence of three Douglas-fir stands (7, 19 and 58 years old, hereafter referred to as HDF00, HDF88 and DF49, respectively) on net C sequestration or net primary productivity measured using the eddy-covariance technique. DF49 (110 ha) and HDF88 (20 ha) were aerially fertilized with urea at 200 kg N ha-1 on Jan 13 and Feb 17, 2007, respectively, while due to its young age and competing understory, fertilizer to HDF00 (5 ha) was manually applied at 80 g urea/tree (60 kg N ha-1) along the tree drip line on Feb 13-14, 2007. Additionally, we calculate the net change in GHG GWP resulting from fertilization of DF49 by accounting for N2O emissions and energy costs of fertilizer production, transport, and application. We also compare polymer-coated slow-release urea (Environmentally Smart Nitrogen (ESN

A discussion of two juxtaposed poems from the said volume explores how the poems’ respective anecdotes and events are segmented, then arranged and sequenced into specific narratives to highlight the speaker’s conviction of the necessity of a biological and spiritual connection with the natural environment. In the larger context of the volume there are numerous other narrative lines (in the form of poems about specific experiences the poet had that are juxtaposed in a similar fashion. Collectively these juxtaposed narrative lines then constitute on the level of the volume as a whole the autobiographical narrative of the poet’s development as self-ironic individual. The various anecdotes also contribute to the formation and development of the theme of symbiosis, a theme that has a direct bearing on how the poet sees the gap between humankind’s current and supposed connection with nature. The main event of the volume is to be found in the reader’s mind: the realisation that bridging this gap is absolutely necessary and that it starts with the individual.

  4. [Vaginoplasty from peritoneal tube of Douglas' poutch for androgen insensitivity syndrome (two case reports)]. (United States)

    Ait Sakel, A; Asseban, M; Kallat, A; Elsayegh, H; Iken, A; Nouini, Y; Benslimane, L; Faik, M


    The androgen insensitivity syndrome (AIS) formerly known as testicular feminization is transmitted on a recessive X-linked. Its diagnosis is usually made at puberty if primary amenorrhea is present because the external genitalia are female. We report the case of two sisters aged 30 and 18 years, with testicular feminization syndrome discovered during the exploration of primary amenorrhea. Clinical examination found fairly well developed mammary glands, an hypertrophied clitoris, two formations in the labia majora corresponding to the testicles and agenesia of vagina. The uterus has not been seen on pelvic ultrasound and computed tomography scan of the pelvis. Cytogenetic analysis has objectified the chromosomal formula: 46 XY. We performed a vaginoplasty using peritoneum from the pouch of Douglas, a clitoroplasty and bilateral orchiectomy. The result was excellent. A neovagina with a depth of 6 cm was created. After 6 months of follow-up, the two sisters keep beautiful vaginal cavities with regular digital dilation. Peritoneum vaginoplasty is a simple and easy method for creating a neovagina with minimal complications. Its anatomical and functional results are satisfactory. Copyright © 2013.

  5. Evaluation of Pushback Decision-Support Tool Concept for Charlotte Douglas International Airport Ramp Operations (United States)

    Hayashi, Miwa; Hoang, Ty; Jung, Yoon C.; Malik, Waqar; Lee, Hanbong; Dulchinos, Victoria L.


    This paper proposes a new departure pushback decision-support tool (DST) for airport ramp-tower controllers. It is based on NASA's Spot and Runway Departure Advisor (SARDA) collaborative decision-making concept, except with the modification that the gate releases now are controlled by tactical pushback (or gate-hold) advisories instead of strategic pre-assignments of target pushback times to individual departure flights. The proposed ramp DST relies on data exchange with the airport traffic control tower (ATCT) to coordinate pushbacks with the ATCT's flow-management intentions under current operational constraints, such as Traffic Management Initiative constraints. Airlines would benefit in reduced taxi delay and fuel burn. The concept was evaluated in a human-in-the-loop simulation experiment with current ramp-tower controllers at the Charlotte Douglas International Airport as participants. The results showed that the tool helped reduce taxi time by one minute per flight and overall departure flight fuel consumption by 10-12% without reducing runway throughput. Expect Departure Clearance Time (EDCT) conformance also was improved when advisories were provided. These benefits were attained without increasing the ramp-tower controllers' workload. Additionally, the advisories reduced the ATCT controllers' workload.

  6. Selection and physiology of cell cultures of Douglas-fir grown under conditions of water stress. (United States)

    Leustek, T; Kirby, E G


    Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) cell cultures sampled 3, 6, or 9 days after subculture in nutrient medium were able to survive subsequent subculture in a medium containing 15% polyethylene glycol (PEG) (M(r) 6000-8000) (-1.21 MPa), whereas cell sampled 12 or 16 days after subculture in nutrient medium became senescent when transferred to a medium containing 15% PEG. Cells sampled after subculture for 3, 6, or 9 days in nutrient medium had lower fresh weight/dry weight ratios, lower osmotic potentials, smaller cell diameters, and higher turgor pressures than cells sampled after 12 or 16 days subculture in nutrient medium. Cells surviving subculture to a medium containing 15% PEG did not increase in dry weight for 5 weeks even though the medium was exchanged every 7 days. After 5 weeks, however, dry weight growth resumed and reached 75% of the level attained by control cells grown on PEG-free medium. Long-term growth on a medium containing 15% PEG (PEG-selected cells) could only be sustained if the medium was supplemented with 30 mM glutamine. The PEG-selected cells grew in small clusters, were isodiametric, and had chlorophyll contents 50% higher than unselected cells. The PEG-selected cells also showed lowered cellular osmotic potentials, presumably due to osmoregulation. Turgor pressures of PEG-selected cells were greater than or equal to those of unselected cells.

  9. Monitoring Aquifer-Storage Change and Land Subsidence Related to Groundwater Withdrawal in the Willcox and Douglas Groundwater Basins in Southeastern Arizona (United States)

    Carruth, R. L.; Conway, B. D.


    Groundwater is the primary source of water in the Willcox and Douglas Basins in southeastern Arizona and about 90 percent of the groundwater withdrawal is for agriculture. It is estimated that current groundwater production exceeds recharge by at least a factor of two in the Douglas Basin and by a factor of three to eight in the Willcox Basin. The groundwater mining has resulted in groundwater declines of as much as 105 feet in the Willcox Basin between 2006 and the present and 52 feet in the Douglas Basin between 2005 and the present. The U.S. Geological Survey collected repeat absolute gravity measurements at 8 sites in the Willcox Basin and at 4 sites in the Douglas Basin for the purpose of measuring the change in aquifer storage between 2008 and 2014. All sites in the Willcox Basin showed aquifer-storage loss between 2008 and 2014, with values ranging from 0.5 to 8.5 feet of water. In the Douglas Basin, two sites showed aquifer-storage loss of 0.8 feet and 3.0 feet, respectively. Additionally, two sites in the Douglas Basin showed storage increases of 2.0 feet and 2.9 feet of water in storage. The storage increases are attributed to the sites being close to ephemeral streams where two large precipitation and associated runoff events (remnant East Pacific hurricanes) occurred shortly before the gravity measurements in 2014. The Arizona Department of Water Resources has identified three major areas of land subsidence using Interferometric Synthetic Aperture Radar (InSAR) data - two in the Willcox Basin and one in the Douglas Basin. Land subsidence of as much as 29 inches in the Willcox Basin and 18 inches in the Douglas Basin has occurred between 2006 and the present—the magnitude and rates of human-induced subsidence have caused earth fissures and impacted roads, a power generation facility, and a railway. The declining groundwater levels, decrease in aquifer storage, and land subsidence are a challenge for future groundwater availability in the Willcox and

  19. In-situ arsenic remediation in Carson Valley, Douglas County, west-central Nevada (United States)

    Paul, Angela P.; Maurer, Douglas K.; Stollenwerk, Kenneth G.; Welch, Alan H.


    Conventional arsenic remediation strategies primarily involve above-ground treatment that include costs involved in the disposal of sludge material. The primary advantages of in-situ remediation are that building and maintaining a large treatment facility are not necessary and that costs associated with the disposal of sludge are eliminated. A two-phase study was implemented to address the feasibility of in-situ arsenic remediation in Douglas County, Nevada. Arsenic concentrations in groundwater within Douglas County range from 1 to 85 micrograms per liter. The primary arsenic species in groundwater at greater than 250 ft from land surface is arsenite; however, in the upper 150 ft of the aquifer arsenate predominates. Where arsenite is the primary form of arsenic, the oxidation of arsenite to arsenate is necessary. The results of the first phase of this investigation indicated that arsenic concentrations can be remediated to below the drinking-water standard using aeration, chlorination, iron, and pH adjustment. Arsenic concentrations were remediated to less than 10 micrograms per liter in groundwater from the shallow and deep aquifer when iron concentrations of 3-6 milligrams per liter and pH adjustments to less than 6 were used. Because of the rapid depletion of dissolved oxygen, the secondary drinking-water standards for iron (300 micrograms per liter) and manganese (100 micrograms per liter) were exceeded during treatment. Treatment was more effective in the shallow well as indicated by a greater recovery of water meeting the arsenic standard. Laboratory and field tests were included in the second phase of this study. Laboratory column experiments using aquifer material indicated the treatment process followed during the first phase of this study will continue to work, without exceeding secondary drinking-water standards, provided that groundwater was pre-aerated and an adequate number of pore volumes treated. During the 147-day laboratory experiment, no

  20. Radiation physics and genetic targeting: new directions for radiotherapy. The Douglas Lea Lecture 1999. (United States)

    Wheldon, T E


    Radiation as a cancer treatment modality is of high physical precision but limited biological specificity. Targeted radiotherapy, the delivery of radiation to cancer cells by radioisotopes conjugated to tumour-seeking targeting agents, is a biologically attractive option but is currently effective for just a few tumour types (neuroblastoma, lymphoma) for which efficacious targeting agents are available. Radiobiological modelling and radiation microdosimetry have provided useful guidelines in choosing treatment strategies for targeted radiotherapy. These considerations generally favour the incorporation of targeted radiotherapy as one component of a multimodal treatment regimen. Very recently, gene therapy techniques have been developed which should enhance the clinical efficacy of both external beam radiation and targeted radiotherapy. Typically, non-harmful viruses are modified to incorporate therapeutic genes which cause altered cellular radiosensitivity or which facilitate the cellular uptake of targeting agents. To achieve specificity, therapeutic genes would be co-transfected with tissue-specific promoter genes causing the therapeutic genes to be expressed in cells of particular types. In laboratory models, our research group are exploring the transfection-mediated uptake of the targeting agents MIBG and sodium iodide. These approaches do not require transfection of every cell in order to cure a tumour-cells which have escaped transfection may be sterilized by radiation cross-fire from transfected neighbours. A new task for radiation microdosimetry is to quantify the cross-fire effect and to compute the efficacies of gene transfection which will be required for tumour cure. In the spirit of Douglas Lea, the analytic approach of physics can be used to illuminate and enhance developments in genetics, to the benefit of medicine.

  1. Nutrition and bud removal affect biomass and nutrient allocation in Douglas-fir and western red cedar. (United States)

    Hawkins, B. J.; Henry, G.


    Seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western red cedar (Thuja plicata J. Donn ex D. Don) were grown at high (250 mg l(-1)) and low (20 mg l(-1)) nitrogen (N) supply for a year. Before the second growing season, half of the seedlings in each nutrient treatment were allocated to the other treatment. Half of the seedlings in each nutrient treatment then had all growing points removed. Biomass and N, phosphorus (P) and potassium (K) concentrations of old and new shoots and roots were measured three times in the second year to test the interaction of current-year and previous-year nutrient supply on biomass and nutrient allocation in these two species with different growth habits. Pruned seedlings served as controls. Unpruned seedlings of both species increased in height throughout the second growing season, except for Douglas-fir in the N250 --> N20 treatment. Repeated pruning did not prevent new shoot growth, but resulted in a 12 to 52% reduction in biomass of new shoots and new and old roots. Seedlings receiving a low N supply in the first growing season were more severely affected by pruning than seedings receiving a high N supply. Growth was reduced more by pruning in western red cedar than in Douglas-fir. Concentrations of N, P and K were higher in pruned seedlings than in unpruned seedlings. Although dry weights of all plant parts in all treatments increased throughout the second growing season, some retranslocation of N, P and K was observed from old shoots of both species in the N250 --> N20 and N20 --> N20 treatments after August. Quantities of N, P and K retranslocated were greatest in seedlings grown the previous year in the high-N treatment.

    A slush hydrogen (SH2) technology facility (STF) was designed, fabricated, and assembled by a contractor team of McDonnell Douglas Aerospace (MDA), Martin Marietta Aerospace Group (MMAG), and Air Products and Chemicals, Inc. (APCI). The STF consists of a slush generator which uses the freeze-thaw production process, a vacuum subsystem, a test tank which simulates the NASP vehicle, a triple point hydrogen receiver tank, a transfer subsystem, a sample bottle, a pressurization system, and a complete instrumentation and control subsystem. The STF was fabricated, checked-out, and made ready for testing under this contract. The actual SH2 testing was performed under the NASP consortium following NASP teaming. Pre-STF testing verified SH2 production methods, validated special SH2 instrumentation, and performed limited SH2 pressurization and expulsion tests which demonstrated the need for gaseous helium pre-pressurized of SH2 to control pressure collapse. The STF represents cutting-edge technology development by an effective Government-Industry team under very tight cost and schedule constraints.

  12. Impact of competitor species composition on predicting diameter growth and survival rates of Douglas-fir trees in southwestern Oregon (United States)

    Bravo, Felipe; Hann, D.W.; Maguire, Douglas A.


    Mixed conifer and hardwood stands in southwestern Oregon were studied to explore the hypothesis that competition effects on individual-tree growth and survival will differ according to the species comprising the competition measure. Likewise, it was hypothesized that competition measures should extrapolate best if crown-based surrogates are given preference over diameter-based (basal area based) surrogates. Diameter growth and probability of survival were modeled for individual Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees growing in pure stands. Alternative models expressing one-sided and two-sided competition as a function of either basal area or crown structure were then applied to other plots in which Douglas-fir was mixed with other conifers and (or) hardwood species. Crown-based variables outperformed basal area based variables as surrogates for one-sided competition in both diameter growth and survival probability, regardless of species composition. In contrast, two-sided competition was best represented by total basal area of competing trees. Surrogates reflecting differences in crown morphology among species relate more closely to the mechanics of competition for light and, hence, facilitate extrapolation to species combinations for which no observations are available.

  13. Finite element model updating of a tied-arch bridge using Douglas-Reid method and Rosenbrock optimization algorithm

    Directory of Open Access Journals (Sweden)

    Tobia Zordan


    Full Text Available Condition assessment of bridges has become increasingly important. In order to accurately simulate the real bridge, finite element (FE model updating method is often applied. This paper presents the calibration of the FE model of a reinforced concrete tied-arch bridge using Douglas-Reid method in combination with Rosenbrock optimization algorithm. Based on original drawings and topographie survey, a FE model of the investigated bridge is created. Eight global modes of vibration of the bridge are identified by ambient vibration tests and the frequency domain decomposition technique. Then, eight structural parameters are selected for FE model updating procedure through sensitivity analysis. Finally, the optimal structural parameters are identified using Rosenbrock optimization algorithm. Results show that although the identified parameters lead to a perfect agreement between approximate and measured natural frequencies, they may not be the optimal variables which minimize the differences between numerical and experimental modal data. However, a satisfied agreement between them is still presented. Hence, FE model updating based on Douglas-Reid method and Rosenbrock optimization algorithm could be used as an alternative to other complex updating procedures.

  14. A study to determine the applicability of noise abatement approach procedures to McDonnell Douglas Aircraft (United States)

    Painter, J. A.; Shannon, J. H.


    Analyses of McDonnell Douglas DC-8, DC-9, and DC-10 jet transports were conducted to investigate the applicability of two segment approach noise abatement procedures to these airplanes. All models had the required glide slope capability at the certified landing flap settings. The DC-8 models would probably be limited to an upper segment glide slope of 5.5 degrees and would probably not be suitable for the two segment procedure in icing conditions. The DC-8 would not be compatible with this procedure at a reduced landing flap setting. The feasibility of installing a two segment approach system in the Douglas-built fleet of commercial jet transports from a hardware viewpoint is discussed. The candidate system consists of a two segment computer plus the necessary peripheral equipment interfaced with the existing autopilot and associated avionics. The required modifications and additions to existing equipment are described and the attendant costs estimated. Potential problems which may be encountered are also discussed.

  15. Effects of mountain beaver management and thinning on 15-year-old Douglas fir growth and survival. (United States)

    Campbell, Dan L; Engeman, Richard M; Farley, James P


    We examined 4-year growth of 15-year-old damaged and undamaged Douglas fir (Pseudotsuga menzesii) after integrating temporary population reductions of mountain beaver (Aplodontia rufa) with thinning in a pre-commercial hand-planted plantation in western Washington. Five treatment combinations were considered: (1) trapping mountain beavers in an unthinned area, (2) trapping before thinning to 65 trees/ha (160 trees/ac), (3) no trapping and thinning to 65 trees/ha, (4) no trapping and thinning to 146 trees/ha (360 trees/ac), and (5) no trapping and no thinning. Removal of ≥ 90 % of mountain beavers temporarily reduced mountain beaver activity whether the stand was unthinned or thinned. Diameter growth at breast height (dbh) was greater for undamaged trees than for damaged trees in thinned areas. Tree height growth was greatest in trapped areas whether thinned or not. No differences were detected in 4-year survival between trees damaged aboveground and those without aboveground damage, which may be related to undetected root damage to trees without aboveground damage. Basal diameter growth and dbh growth were greatest for areas thinned to 65 trees/ha. Seventy-eight percent of stomachs from mountain beaver trapped in winter contained Douglas fir root or stem materials. Overall, short-term removal of mountain beavers integrated with pre-commercial thinning promoted growth of crop trees.

  16. Height-growth response to climatic changes differs among populations of Douglas-fir: a novel analysis of historic data. (United States)

    Leites, Laura P; Robinson, Andrew P; Rehfeldt, Gerald E; Marshall, John D; Crookston, Nicholas L


    Projected climate change will affect existing forests, as substantial changes are predicted to occur during their life spans. Species that have ample intraspecific genetic differentiation, such as Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), are expected to display population-specific growth responses to climate change. Using a mixed-effects modeling approach, we describe three-year height (HT) growth response to changes in climate of interior Douglas-fir populations. We incorporate climate information at the population level, yielding a model that is specific to both species and population. We use data from provenance tests from previous studies that comprised 236 populations from Idaho, Montana, and eastern Washington, USA. The most sensitive indicator of climate was the mean temperature of the coldest month. Population maximum HT and HT growth response to changes in climate were dependent on seed source climate. All populations had optimum HT growth when transferred to climates with warmer winters; those originating in sites with the warmest winters were taller across sites and had highest HT growth at transfer distances closest to zero; those from colder climates were shortest and had optimum HT growth when transferred the farthest. Although this differential response damped the height growth differences among populations, cold-climate populations still achieved their maximum growth at lower temperatures than warm-climate populations. The results highlight the relevance of understanding climate change impacts at the population level, particularly in a species with ample genetic variation among populations.

    Pickles, Brian J; Twieg, Brendan D; O'Neill, Gregory A; Mohn, William W; Simard, Suzanne W


    Separating edaphic impacts on tree distributions from those of climate and geography is notoriously difficult. Aboveground and belowground factors play important roles, and determining their relative contribution to tree success will greatly assist in refining predictive models and forestry strategies in a changing climate. In a common glasshouse, seedlings of interior Douglas-fir (Pseudotsuga menziesii var. glauca) from multiple populations were grown in multiple forest soils. Fungicide was applied to half of the seedlings to separate soil fungal and nonfungal impacts on seedling performance. Soils of varying geographic and climatic distance from seed origin were compared, using a transfer function approach. Seedling height and biomass were optimized following seed transfer into drier soils, whereas survival was optimized when elevation transfer was minimised. Fungicide application reduced ectomycorrhizal root colonization by c. 50%, with treated seedlings exhibiting greater survival but reduced biomass. Local adaptation of Douglas-fir populations to soils was mediated by soil fungi to some extent in 56% of soil origin by response variable combinations. Mediation by edaphic factors in general occurred in 81% of combinations. Soil biota, hitherto unaccounted for in climate models, interacts with biogeography to influence plant ranges in a changing climate. © 2015 The Authors. New Phytologist © 2015 New Phytologist Trust.

    Carlos P. Zalaquett


    Full Text Available Cyberbullying is commonly presented as affecting K-12 populations. Current research suggests cyberbullying continues in college. A diverse sample of 613 university students was surveyed to study their cyberbullying experiences in high school and college. Nineteen percent of the sample reported being a victim of cyberbullying in college and 35% of this subsample reported being cyberbullied in high school. Additional findings and practical implications are presented.

  1. Using Site-Specific Habitat Information on Young to Late Successional Avifauna to Guide Use and Management of Coastal Redwood and Douglas-Fir Forest Lands (United States)

    Sal J. Chinnici; Laura C. Bradley; Daniel R. Dill; David Bigger


    Conservation of avifauna in coastal redwood (Sequoia sempervirens) and Douglas-fir (Pseudosteuga menziesii) managed forestlands has historically involved two opposing goals. First, landowners want to minimize restricted acreage in order to maximize commercial utilization of forest products. Second, poor scientific understanding of...

    Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) in the Inland Northwest region of the USA are nitrogen (N) deficient; however stem growth responses to N fertilizers are unpredictable, which may be due to poor accounting of other limiting nutrients. Screening trial experiments, including potassium (K), sulfur (S), and boron (B) multiple nutrient treatments, have been...

  5. Long-term patterns of diameter and basal area growth of old-growth Douglas-fir trees in western Oregon (United States)

    Poage, Nathan; Tappeiner, J. C.


    Diameter growth and age data collected from stumps of 505 recently cut old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees at 28 sample locations in western Oregon (U.S.A.) indicated that rapid early and sustained growth of old Douglas-fir trees were extremely important in terms of attaining large diameters at ages 100a??300 years. The diameters of the trees at ages 100a??300 years (D100a??D300) were strongly, positively, and linearly related to their diameters and basal area growth rates at age 50 years. Average periodic basal area increments (PAIBA) of all trees increased for the first 30a??40 years and then plateaued, remaining relatively high and constant from age 50 to 300 years. Average PAIBA of the largest trees at ages 100a??300 years were significantly greater by age 20 years than were those of smaller trees at ages 100a??300 years. The site factors province, site class, slope, aspect, elevation, and establishment year accounted for little of the variation observed in basal area growth at age 50 years and D100a??D300. The mean age range for old-growth Douglas-fir at the sample locations was wide (174 years). The hypothesis that large-diameter old-growth Douglas-fir developed at low stand densities was supported by these observations.

  6. College residential sleep environment. (United States)

    Sexton-Radek, Kathy; Hartley, Andrew


    College students regularly report increased sleep disturbances as well as concomitant reductions in performance (e.g., academic grades) upon entering college. Sleep hygiene refers to healthy sleep practices that are commonly used as first interventions in sleep disturbances. One widely used practice of this sort involves arranging the sleep environment to minimize disturbances from excessive noise and light at bedtime. Communal sleep situations such as those in college residence halls do not easily support this intervention. Following several focus groups, a questionnaire was designed to gather self-reported information on sleep disturbances in a college population. The present study used The Young Adult Sleep Environment Inventory (YASEI) and sleep logs to investigate the sleep environment of college students living in residential halls. A summary of responses indicated that noise and light are significant sleep disturbances in these environments. Recommendations are presented related to these findings.

  7. 'Life?': modernism and liminality in Douglas Livingstone’s A littoral zone

    Directory of Open Access Journals (Sweden)

    E. Terblanche


    Full Text Available In an attempt to find his place within nature in South Africa and in a global modern context, Douglas Livingstone returns strongly to modernist poetry in his 1991 volume A littoral zone. In contrast to his predecessors like Wallace Stevens in “The glass of water” and T.S. Eliot in The waste land, this volume at critical moments gets stuck in a liminal stage. Images and poems, and eventually the volume as a whole, despite the highlights they present, say that it no longer seems so possible to end up also within the postliminal stage, so as to complete a rite of passage. Yet modernist poems such as Stevens’s “The glass of water” have the ability to end up in postliminal affirmation through and beyond the liminal stage of the overall process. Here light becomes a thirsty lion that comes down to drink from the glass, with a resultant transcendence of the dualistic between-ness that characterises the liminal stage in the modernist poetic mode, while this further results in the incorporation of a deeper and refreshing, dynamic unity. Even more remarkable is that this poetic rite is not of a closing nature, but open, especially in the sense that it affirms all that is possible and greater than the individual ego or subject, this, while getting stuck within a liminal stage just short of the postliminal stage can be in the nature of closure, as Livingstone shows, for example, when he says in “Low tide at Station 20” that humanity is trapped in its inability to see the original power of unity with and within nature in order to live within it; and while humanity remains an ugly outgrowth on the gigantic spine of evolution. In provisional conclusion this article finds that it will be better to view Victor Turner’s 1979 celebration of what he terms the “liminoid” in the place of a “true liminality” critically. Although it is impossible to return to a collective catharsis in watching a play, one cannot feel too comfortable about

  12. Relation of initial spacing and relative stand density indices to stand characteristics in a Douglas-fir plantation spacing trial (United States)

    Curtis, Robert O.; Bansal, Sheel; Harrington, Constance A.


    This report presents updated information on a 1981 Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantation spacing trial at 33 years from planting. Stand statistics at the most recent measurement were compared for initial spacing of 1 through 6 meters and associated relative densities. There was no clear relationship of spacing to top height. Diameter, live crown ratio, and percent survival increased with spacing; basal area and relative density decreased with increase in spacing. Volume in trees ≥ 4 cm diameter was greatest at 2 m spacing, while utilizable volume (trees ≥20 cm dbh) was greatest at 4 m spacing. Live crown ratio decreased and total crown projectional area increased with increasing relative density indices. Total crown projectional area was more closely related to relative density than to basal area.

  13. Economic impact due to Cimanuk river flood disaster in Garut district using Cobb-Douglas analysis with least square method (United States)

    Bestari, T. A. S.; Supian, S.; Purwani, S.


    Cimanuk River, Garut District, West Java which have upper course in Papandayan Mountain have an important purpose in dialy living of Garut people as a water source. But in 2016 flash flood in this river was hitted and there was 26 peple dead and 23 peole gone. Flash flood which hitted last year make the settlement almost align with the ground, soaking school and hospital. BPLHD Jawa Barat saw this condition as a disaster which coused by distroyed upper course of Cimanuk River. Flash Flood which happened on the 2016 had ever made economic sector paralized. Least square method selected to analyze economic condition in residents affected post disaster, after the mathematical equations was determined by Cobb Douglas Method. By searching proportion value of the damage, and the result expected became a view to the stakeholder to know which sector that become a worse and be able to make a priority in development

  14. Will changes in phenology track climate change? A study of growth initiation timing in coast Douglas-fir (United States)

    Ford, Kevin R.; Harrington, Constance A.; Bansal, Sheel; Gould, Petter J.; St. Clair, Bradley


    Under climate change, the reduction of frost risk, onset of warm temperatures and depletion of soil moisture are all likely to occur earlier in the year in many temperate regions. The resilience of tree species will depend on their ability to track these changes in climate with shifts in phenology that lead to earlier growth initiation in the spring. Exposure to warm temperatures (“forcing”) typically triggers growth initiation, but many trees also require exposure to cool temperatures (“chilling”) while dormant to readily initiate growth in the spring. If warming increases forcing and decreases chilling, climate change could maintain, advance or delay growth initiation phenology relative to the onset of favorable conditions. We modeled the timing of height- and diameter-growth initiation in coast Douglas-fir (an ecologically and economically vital tree in western North America) to determine whether changes in phenology are likely to track changes in climate using data from field-based and controlled-environment studies, which included conditions warmer than those currently experienced in the tree's range. For high latitude and elevation portions of the tree's range, our models predicted that warming will lead to earlier growth initiation and allow trees to track changes in the onset of the warm but still moist conditions that favor growth, generally without substantially greater exposure to frost. In contrast, towards lower latitude and elevation range limits, the models predicted that warming will lead to delayed growth initiation relative to changes in climate due to reduced chilling, with trees failing to capture favorable conditions in the earlier parts of the spring. This maladaptive response to climate change was more prevalent for diameter-growth initiation than height-growth initiation. The decoupling of growth initiation with the onset of favorable climatic conditions could reduce the resilience of coast Douglas-fir to climate change at the warm
