    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.

  1. 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.

  7. 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.

  17. 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

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

    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.

    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.

  17. 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.

  20. The Circle of Prosperity: Tribal Colleges, Tradition, and Technology -- Building Synergistic Cross-Community Collaborations (United States)

    Billy, C. L.


    For more than three decades, American Indian Tribal Colleges and Universities have been working to sustain what is ours: our land, our language, our communities, and our culture. Tribal Colleges have achieved success by helping our communities, located in some of the poorest and most geographically remote areas of the country, develop systems for higher education, research, and economic development that are accessible, culturally responsive, and place-based. American Indian higher education is holistic, focused on the mind, body, spirit, and family. Research is respectful of culture, mindful of community values, and essential to community well-being. Economic development strategies are based on national and international trends, but focused on relationships between local people and their land. In this environment, applied research flourishes and new knowledge, integrating traditional ways of knowing with western science, is created and used. In the 1990s, the American Indian Higher Education Consortium, which is composed of 35 Tribal Colleges and Universities in the U.S. and Canada, launched a major initiative to expand and enhance this capacity through new collaborations and state-of-the-art information and communications technologies. Through a multi-phase effort, the Tribal Colleges developed and are currently implementing a dynamic and broad-based strategic plan. The goal: to reach a "Circle of Prosperity," a place where tribal traditions and new technologies are woven together to build stronger and more sustainable communities through enhanced STEM education and research programs. Our plan, the "Tribal College Framework for Community Technology," is a framework of strategic partnerships, resources, and tools that is helping us create locally based economic and social opportunities through information and communications technology and use of the Internet. During this presentation, we will: (a) discuss the innovative collaborative process we are using to build

  9. 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.

  11. 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)

  17. Lagrangians for generalized Argyres-Douglas theories (United States)

    Benvenuti, Sergio; Giacomelli, Simone


    We continue the study of Lagrangian descriptions of N=2 Argyres-Douglas theories. We use our recent interpretation in terms of sequential confinement to guess the Lagrangians of all the Argyres-Douglas models with Abelian three dimensional mirror. We find classes of four dimensional N=1 quivers that flow in the infrared to generalized Argyres-Douglas theories, such as the ( A k , A kN + N -1) models. We study in detail how the N=1 chiral rings map to the Coulomb and Higgs Branches of the N=2 CFT's. The three dimensional mirror RG flows are shown to land on the N=4 complete graph quivers. We also compactify to three dimensions the gauge theory dual to ( A 1, D 4), and find the expected Abelianization duality with N=4 SQED with 3 flavors.

  18. Achievement, Language, and Technology Use Among College-Bound Deaf Learners. (United States)

    Crowe, Kathryn; Marschark, Marc; Dammeyer, Jesper; Lehane, Christine


    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.

  19. The Use of Vocational Guidance E-Systems in Colleges of Technology, Saudi Arabia (United States)

    Alsaidan, Saad; Zhang, Li


    This study aimed to explore how much interest do technical colleges students have in vocational guidance E-Systems and to detect the most important E-Systems of vocational guidance that they use. The researcher collected data, through questionnaires, from 311 students in their fourth, fifth, or sixth semesters in the colleges of technology in Saudi Arabia. The data were analysed using the chi square test, factor analysis, and descriptive analysis. This study shows the importance in the integration of the E-Systems to vocational guidance. The model includes: the use of e-vocational consulting programs, e-extracurricular programs, e-vocational activities, informational systems, and e-exams for vocational tendency, which were rarely studied before. The results indicated that the college student is highly motivated by vocational guidance using the E-system, unlike the traditional methods of vocational guidance, and young students are motivated by the E-system when it is used in vocational guidance. The study conclude that the integration of the E-system has significantly contributed to vocational guidance. The study recommends that the e-system be implemented to all areas of decision-making. Practitioners should Interact with students through the E-Systems and arrive at decisions that are good for educational growth.

  20. 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.

  4. Capitalizing on mobile technology to support healthy eating in ethnic minority college students. (United States)

    Rodgers, Rachel F; Pernal, Wendy; Matsumoto, Atsushi; Shiyko, Mariya; Intille, Stephen; Franko, Debra L


    To evaluate the capacity of a mobile technology-based intervention to support healthy eating among ethnic minority female students. Forty-three African American and Hispanic female students participated in a 3-week intervention between January and May 2013. Participants photographed their meals using their smart phone camera and received motivational text messages 3 times a day. At baseline, postintervention, and 10 weeks after the intervention, participants reported on fruit, vegetable, and sugar-sweetened beverage consumption. Participants were also weighed at baseline. Among participants with body mass index (BMI) ≥25, fruit and vegetable consumption increased with time (p technology-based interventions could facilitate healthy eating among female ethnic minority college students, particularly those with higher BMI.

  5. 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.

  6. Inheritance of graft compatibility in Douglas fir. (United States)

    D.L. Copes


    Graft compatibility of genetically related and unrelated rootstock-scion combinations was compared. Scion clones were 75% compatible when grafted on half-related rootstocks but only 56% compatible when grafted on unrelated rootstocks. Most variance associated with graft incompatibility in Douglas-fir appears to be caused by multiple genes.

  8. Time for a Change: College Students' Preference for Technology-Mediated Versus Face-to-Face Help for Emotional Distress. (United States)

    Lungu, Anita; Sun, Michael


    Even with recent advances in psychological treatments and mobile technology, online computerized therapy is not yet popular. College students, with ubiquitous access to technology, experiencing high distress, and often nontreatment seekers, could be an important area for online treatment dissemination. Finding ways to reach out to college students by offering psychological interventions through technology, devices, and applications they often use, might increase their engagement in treatment. This study evaluates college students' reported willingness to seek help for emotional distress through novel delivery mediums, to play computer games for learning emotional coping skills, and to disclose personal information online. We also evaluated the role of ethnicity and level of emotional distress in help-seeking patterns. A survey exploring our domains of interest and the Mental Health Inventory ([MHI] as mental health index) were completed by 572 students (mean age 18.7 years, predominantly Asian American, female, and freshmen in college). More participants expressed preference for online versus face-to-face professional help. We found no relationship between MHI and help-seeking preference. A third of participants were likely to disclose at least as much information online as face-to-face. Ownership of mobile technology was pervasive. Asian Americans were more likely to be nontreatment seekers than Caucasians. Most participants were interested in serious games for emotional distress. Our results suggest that college students are very open to creative ways of receiving emotional help such as playing games and seeking emotional help online, suggesting a need for online evidence-based treatments.

  13. 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.

  14. Science, technology, engineering, and mathematics (STEM) participation among college students with an autism spectrum disorder. (United States)

    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.

  15. Experiments in Creative Engineering at the Department of Mechanical Engineering in Kurume National College of Technology (United States)

    Tanaka, Hiroshi; Hashimura, Shinji; Hiroo, Yasuaki

    We present a program to learn ability to solve problems on engineering. This program is called “Experiments in creative engineering” in the department of mechanical engineering in Kurume National College of Technology advanced engineering school. In the program, students have to determine own theme and manufacture experimental devices or some machines by themselves. The students must also perform experiments to valid the function and performance of their devices by themselves. The restriction of the theme is to manufacture a device which function dose not basically exist in the world with limited cost (up to 20,000Yen) . As the results of questionnaire of students, the program would be very effective to the creative education for the students.

  16. The Douglas-Fir Genome Sequence Reveals Specialization of the Photosynthetic Apparatus in Pinaceae

    Directory of Open Access Journals (Sweden)

    David B. Neale


    Full Text Available A reference genome sequence for Pseudotsuga menziesii var. menziesii (Mirb. Franco (Coastal Douglas-fir is reported, thus providing a reference sequence for a third genus of the family Pinaceae. The contiguity and quality of the genome assembly far exceeds that of other conifer reference genome sequences (contig N50 = 44,136 bp and scaffold N50 = 340,704 bp. Incremental improvements in sequencing and assembly technologies are in part responsible for the higher quality reference genome, but it may also be due to a slightly lower exact repeat content in Douglas-fir vs. pine and spruce. Comparative genome annotation with angiosperm species reveals gene-family expansion and contraction in Douglas-fir and other conifers which may account for some of the major morphological and physiological differences between the two major plant groups. Notable differences in the size of the NDH-complex gene family and genes underlying the functional basis of shade tolerance/intolerance were observed. This reference genome sequence not only provides an important resource for Douglas-fir breeders and geneticists but also sheds additional light on the evolutionary processes that have led to the divergence of modern angiosperms from the more ancient gymnosperms.

  6. A Canadian paradox: Tommy Douglas and eugenics. (United States)

    Shevell, Michael


    Tommy Douglas is an icon of Canadian 20th Century political history and is considered by many as the "Father" of Medicare, a key component of our national identity. Throughout his career, he was associated at both the provincial and federal levels with progressive causes concerning disadvantaged populations. In his sociology Master's thesis written in the early 1930's, Douglas endorsed eugenic oriented solutions such as segregation and sterilization to address what was perceived to be an endemic and biologically determined problem. At first glance, this endorsement of eugenics appears to be paradoxical, but careful analysis revealed that this paradox has multiple roots in religion, political belief, historical exposure and our own desire to view our collective history in a favourable light.

  7. On Berenstein-Douglas-Seiberg duality

    International Nuclear Information System (INIS)

    Braun, Volker


    I review the proposal of Berenstein-Douglas for a completely general definition of Seiberg duality. To give evidence for their conjecture I present the first example of a physical dual pair and explicitly check that it satisfies the requirements. Then I explicitly show that a pair of toric dual quivers is also dual according to their proposal. All these computations go beyond tilting modules, and really work in the derived category. I introduce all necessary mathematics where needed. (author)

  8. The effect of gender, ethnicity, and income on college students' use of communication technologies. (United States)

    Junco, Reynol; Merson, Dan; Salter, Daniel W


    Because campus officials are relying on personal communication technologies to communicate with students, a question arises about access and usage. Although communication technologies are popular among college students, some evidence suggests that differences exist in ownership and use. We examined patterns of student ownership and use of cell phones and use of instant messaging, focusing on three predictors of digital inequality: gender, ethnicity, and income. Logistic and hierarchical linear regression analyses were used to analyze results from 4,491 students. The odds that female and white students owned cell phones were more than twice as high as for men and African-American students. Students in the $100,000-$149,000 per year income bracket were more than three times as likely to own a cell phone than those from the median bracket. However, being female, African-American, and/or from the highest income brackets was positively predictive of the number of text messages sent and the amount of time spent talking on a cell phone per week. We found no differences between students on the use of instant messaging. Implications of these results, as well as areas for further research, are provided.

  9. 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.

  19. 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.

    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

  2. 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.

    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

  4. Characteristics Associated with Persistence and Retention among First-Generation College Students Majoring in Science, Technology, Engineering, or Math (United States)

    Burnett, Lorie Lasseter

    Persistence and retention of college students is a great concern in American higher education. The dropout rate is even more apparent among first-generation college students, as well as those majoring in science, technology, engineering, and math (STEM). More students earning STEM degrees are needed to fill the many jobs that require the skills obtained while in college. More importantly, those students who are associated with a low-socioeconomic background may use a degree to overcome poverty. Although many studies have been conducted to determine the characteristics associated with student attrition among first-generation students or STEM majors, very little information exists in terms of persistence and retention among the combined groups. The current qualitative study identified some of the characteristics associated with persistence and retention among first-generation college students who are also STEM majors. Participants were juniors or seniors enrolled at a regional 4-year institution. Face-to-face interviews were conducted to allow participants to share their personal experiences as first-generation STEM majors who continue to persist and be retained by their institution. Tinto's Theory of Individual Departure (1987) was used as a framework for the investigation. This theory emphasizes personal and academic background, personal goals, disconnecting from one's own culture, and institutional integration as predictors of persistence. The findings of the investigation revealed that persisting first-generation STEM majors are often connected to family, but have been able to separate that connection with that of the institution. They also are goal-driven and highly motivated and have had varied pre-college academic experiences. These students are academically integrated and socially integrated in some ways, but less than their non-first-generation counterparts. They are overcoming obstacles that students from other backgrounds may not experience. They receive

  5. THE FLAG: A Web Resource of Innovative Assessment Tools for Faculty in College Science, Mathematics, Engineering, and Technology (United States)

    Zeilik, M.; Mathieu, R. D.; National InstituteScience Education; College Level-One Team


    Even the most dedicated college faculty often discover that their students fail to learn what was taught in their courses and that much of what students do learn is quickly forgotten after the final exam. To help college faculty improve student learning in college Science, Mathematics, Engineering and Technology (SMET), the College Level - One Team of the National Institute for Science Education has created the "FLAG" a Field-tested Learning Assessment Guide for SMET faculty. Developed with funding from the National Science Foundation, the FLAG presents in guidebook format a diverse and robust collection of field-tested classroom assessment techniques (CATs), with supporting information on how to apply them in the classroom. Faculty can download the tools and techniques from the website, which also provides a goals clarifier, an assessment primer, a searchable database, and links to additional resources. The CATs and tools have been reviewed by an expert editorial board and the NISE team. These assessment strategies can help faculty improve the learning environments in their SMET courses especially the crucial introductory courses that most strongly shape students' college learning experiences. In addition, the FLAG includes the web-based Student Assessment of Learning Gains. The SALG offers a convenient way to evaluate the impact of your courses on students. It is based on findings that students' estimates of what they gained are more reliable and informative than their observations of what they liked about the course or teacher. It offers accurate feedback on how well the different aspects of teaching helped the students to learn. Students complete the SALG online after a generic template has been modified to fit the learning objectives and activities of your course. The results are presented to the teacher as summary statistics automatically. The FLAG can be found at the NISE "Innovations in SMET Education" website at

  6. Remotely controlled repair at Douglas Point

    International Nuclear Information System (INIS)



    The Douglas Point nuclear generating station, completed in 1966, was Canada's first venture in commercial nuclear power. The discovery, 11 years later, of two perforations in auxiliary piping in a high radiation area led Atomic Energy of Canada Ltd and Ontario Hydro to develop new approaches to remotely controlled repair that will have much wider applications. Eddy current and ultrasonic testing were used to determine the pattern and extent of wear in a pipe encircled by a U-bolt, without first removing the U-bolt. Progress was monitored using remote TV cameras. Welding tools were designed and fabricated for the repairs, and a manipulator was also designed to transport the tool into its place of work. (author)

  12. 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.

  16. 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.

  17. 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

  20. 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

  20. 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.

  1. 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.

  2. N =1 Lagrangians for generalized Argyres-Douglas theories (United States)

    Agarwal, Prarit; Sciarappa, Antonio; Song, Jaewon


    We find N = 1 Lagrangian gauge theories that flow to generalized ArgyresDouglas theories with N = 2 supersymmetry. We find that certain SU quiver gauge theories flow to generalized Argyres-Douglas theories of type ( A k-1 , A mk-1) and ( I m,km , S). We also find quiver gauge theories of SO/Sp gauge groups flowing to the ( A 2 m-1 , D 2 mk+1), ( A 2 m , D 2 m( k-1)+ k ) and D m(2 k + 2) m(2 k + 2) [ m] theories.

  3. Matrix models, Argyres-Douglas singularities and double scaling limits

    International Nuclear Information System (INIS)

    Bertoldi, Gaetano


    We construct an N = 1 theory with gauge group U(nN) and degree n+1 tree level superpotential whose matrix model spectral curve develops an Argyres-Douglas singularity. The calculation of the tension of domain walls in the U(nN) theory shows that the standard large-N expansion breaks down at the Argyres-Douglas points, with tension that scales as a fractional power of N. Nevertheless, it is possible to define appropriate double scaling limits which are conjectured to yield the tension of 2-branes in the resulting N = 1 four dimensional non-critical string theories as proposed by Ferrari.

    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

  14. Schur indices, BPS particles, and Argyres-Douglas theories

    International Nuclear Information System (INIS)

    Córdova, Clay; Shao, Shu-Heng


    We conjecture a precise relationship between the Schur limit of the superconformal index of four-dimensional N=2 field theories, which counts local operators, and the spectrum of BPS particles on the Coulomb branch. We verify this conjecture for the special case of free field theories, N=2 QED, and SU(2) gauge theory coupled to fundamental matter. Assuming the validity of our proposal, we compute the Schur index of all Argyres-Douglas theories. Our answers match expectations from the connection of Schur operators with two-dimensional chiral algebras. Based on our results we propose that the chiral algebra of the generalized Argyres-Douglas theory (A_k_−_1,A_N_−_1) with k and N coprime, is the vacuum sector of the (k,k+N)W_k minimal model, and that the Schur index is the associated vacuum character.

  15. 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

    We retrospectively reviewed barium enema and CT findings of Douglas pouch metastasis in 170 patients. The findings were divided into three types: Anterior compression type, anterior fixed folds type, and stenosis type. Patients with gastric cancer usually showed a stenosis type, especially in those with poorly differentiated adenocarcinoma. Patients with colon and ovary cancer usually showed an anterior compression type. In patients with gastric cancer, those who showed a stenosis type had the most favorable prognosis among these three types. (author)

  20. Douglas-fir displays a range of growth responses to ... (United States)

    Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) growth in the Pacific Northwest is affected by climatic, edaphic factors and Swiss needle cast (SNC) disease. We examine Douglas-fir growth responses to temperature, dewpoint deficit (DPD), soil moisture, and SNC using time series intervention analysis of intra-annual tree-ring width data collected at nine forest stands in western Oregon, USA. The effects of temperature and SNC were similar in importance on tree growth at all sites. Previous-year DPD during the annual drought period was a key factor limiting growth regionally. Winter temperature was more important at high elevation cool sites, whereas summer temperature was more important at warm and dry sites. Growth rate increased with summer temperature to an optimum (Topt) then decreased at higher temperatures. At drier sites, temperature and water affected growth interactively such that Topt decreased with decreasing summer soil moisture. With climate change, growth rates increased at high elevation sites and declined at mid-elevation inland sites since ~1990. Growth response to climate is masked by SNC regionally. We conclude that as temperature rises and precipitation patterns shift towards wetter winters and drier summers, Douglas-fir will experience greater temperature and water stress and an increase in severity of SNC. By the end of the 21st century, climate models predict hotter, drier summers and warmer, wetter winters in the Pac

  13. The Mode Reform of Cultivating Marketing Talents in Agricultural Vocational Colleges Based on the Perspective of Agricultural Enterprises——A Case Study of Wenzhou Vocational College of Science and Technology

    Institute of Scientific and Technical Information of China (English)


    We conduct survey on the characteristics of demand of agricultural enterprises for agricultural marketing talents from the following 6 aspects:the professional marketing talents needed urgently by the agricultural enterprises,the amount of demand of agricultural enterprises for the marketing talents,the jobs offered by the agricultural enterprises,the educational background of agricultural marketing talents favored by the agricultural enterprises,the requirements posed by the agricultural enterprises on the work experience of agricultural marketing talents,and the quality requirements posed by the agricultural enterprises on the agricultural marketing talents.We analyse the problems existing in the cultivation mode of marketing talents in agricultural vocational colleges as follows:the feature of major is not outstanding;the contradiction between supply and demand is prominent;it is disconnected with the practical needs of agricultural enterprises;the cultivation form of practical ability is simple.On the basis of this,taking Wenzhou Vocational College of Science and Technology as an example,we advance the new mode of cultivating inter-disciplinary talents integrating "marketing technique+technique marketing",and establish characteristic agricultural course combo system on the basis of vocational position orientation.In the meantime,we propose that we should conduct close college-enterprise cooperation with the local leading agricultural enterprises.This cultivation mode reform of talents is favorable for the agricultural enterprises,especially small and medium-sized agricultural enterprises to foster "marketable" agricultural marketing talents,elevate the comprehensive competitiveness of small and medium-sized agricultural enterprises,serve the local economy,and promote the development of modern agriculture,and China’s agriculture,farmer,and countryside.

  19. 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

  20. Bootstrapping the (A1, A2) Argyres-Douglas theory (United States)

    Cornagliotto, Martina; Lemos, Madalena; Liendo, Pedro


    We apply bootstrap techniques in order to constrain the CFT data of the ( A 1 , A 2) Argyres-Douglas theory, which is arguably the simplest of the Argyres-Douglas models. We study the four-point function of its single Coulomb branch chiral ring generator and put numerical bounds on the low-lying spectrum of the theory. Of particular interest is an infinite family of semi-short multiplets labeled by the spin ℓ. Although the conformal dimensions of these multiplets are protected, their three-point functions are not. Using the numerical bootstrap we impose rigorous upper and lower bounds on their values for spins up to ℓ = 20. Through a recently obtained inversion formula, we also estimate them for sufficiently large ℓ, and the comparison of both approaches shows consistent results. We also give a rigorous numerical range for the OPE coefficient of the next operator in the chiral ring, and estimates for the dimension of the first R-symmetry neutral non-protected multiplet for small spin.

  1. Structural properties of laminated Douglas fir/epoxy composite material

    Energy Technology Data Exchange (ETDEWEB)

    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.

  3. 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

  5. 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.

  6. ODE/IM correspondence and the Argyres-Douglas theory (United States)

    Ito, Katsushi; Shu, Hongfei


    We study the quantum spectral curve of the Argyres-Douglas theories in the Nekrasov-Sahashvili limit of the Omega-background. Using the ODE/IM correspondence we investigate the quantum integrable model corresponding to the quantum spectral curve. We show that the models for the A 2 N -type theories are non-unitary coset models ( A 1)1 × ( A 1) L /( A 1) L+1 at the fractional level L=2/2N+1-2 , which appear in the study of the 4d/2d correspondence of N = 2 superconformal field theories. Based on the WKB analysis, we clarify the relation between the Y-functions and the quantum periods and study the exact Bohr-Sommerfeld quantization condition for the quantum periods. We also discuss the quantum spectral curves for the D and E type theories.

  7. Argyres-Douglas theories, chiral algebras and wild Hitchin characters (United States)

    Fredrickson, Laura; Pei, Du; Yan, Wenbin; Ye, Ke


    We use Coulomb branch indices of Argyres-Douglas theories on S 1 × L( k, 1) to quantize moduli spaces M_H of wild/irregular Hitchin systems. In particular, we obtain formulae for the "wild Hitchin characters" — the graded dimensions of the Hilbert spaces from quantization — for four infinite families of M_H , giving access to many interesting geometric and topological data of these moduli spaces. We observe that the wild Hitchin characters can always be written as a sum over fixed points in M_H under the U(1) Hitchin action, and a limit of them can be identified with matrix elements of the modular transform ST k S in certain two-dimensional chiral algebras. Although naturally fitting into the geometric Langlands program, the appearance of chiral algebras, which was known previously to be associated with Schur operators but not Coulomb branch operators, is somewhat surprising.

  8. 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

  14. 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.

  15. 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.

  16. 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

    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}.

    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.

  5. 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

  13. 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.

  14. A SNP resource for Douglas-fir: de novo transcriptome assembly and SNP detection and validation. (United States)

    Howe, Glenn T; Yu, Jianbin; Knaus, Brian; Cronn, Richard; Kolpak, Scott; Dolan, Peter; Lorenz, W Walter; Dean, Jeffrey F D


    Douglas-fir (Pseudotsuga menziesii), one of the most economically and ecologically important tree species in the world, also has one of the largest tree breeding programs. Although the coastal and interior varieties of Douglas-fir (vars. menziesii and glauca) are native to North America, the coastal variety is also widely planted for timber production in Europe, New Zealand, Australia, and Chile. Our main goal was to develop a SNP resource large enough to facilitate genomic selection in Douglas-fir breeding programs. To accomplish this, we developed a 454-based reference transcriptome for coastal Douglas-fir, annotated and evaluated the quality of the reference, identified putative SNPs, and then validated a sample of those SNPs using the Illumina Infinium genotyping platform. We assembled a reference transcriptome consisting of 25,002 isogroups (unique gene models) and 102,623 singletons from 2.76 million 454 and Sanger cDNA sequences from coastal Douglas-fir. We identified 278,979 unique SNPs by mapping the 454 and Sanger sequences to the reference, and by mapping four datasets of Illumina cDNA sequences from multiple seed sources, genotypes, and tissues. The Illumina datasets represented coastal Douglas-fir (64.00 and 13.41 million reads), interior Douglas-fir (80.45 million reads), and a Yakima population similar to interior Douglas-fir (8.99 million reads). We assayed 8067 SNPs on 260 trees using an Illumina Infinium SNP genotyping array. Of these SNPs, 5847 (72.5%) were called successfully and were polymorphic. Based on our validation efficiency, our SNP database may contain as many as ~200,000 true SNPs, and as many as ~69,000 SNPs that could be genotyped at ~20,000 gene loci using an Infinium II array-more SNPs than are needed to use genomic selection in tree breeding programs. Ultimately, these genomic resources will enhance Douglas-fir breeding and allow us to better understand landscape-scale patterns of genetic variation and potential responses to

  15. 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.

  18. 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.

  19. 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.

  1. Access, attitudes and training in information technologies and evidence-based medicine among medical students at University of Zimbabwe College of Health Sciences. (United States)

    Parve, Swapnil; Ershadi, Ali; Karimov, Alexandr; Dougherty, Anne; Ndhlovu, Chiratidzo E; Chidzonga, Midion M; Sadigh, Majid


    The Medical Education Partnership Initiative, has helped to mitigate the digital divide in Africa. The aim of the study was to assess the level of access, attitude, and training concerning meaningful use of electronic resources and EBM among medical students at an African medical school. The study involved medical students at the University of Zimbabwe College of Health Sciences, Harare. The needs assessment tool consisted of a 21-question, paper-based, voluntary and anonymous survey. A total of 61/67 (91%), responded to the survey. 60% of the medical students were 'third-year medical students'. Among medical students, 85% of responders had access to digital medical resources, but 54% still preferred printed medical textbooks. Although 25% of responders had received training in EBM, but only 7% found it adequate. 98% of the participants did not receive formal training in journal club presentation or analytical reading of medical literature, but 77 % of them showed interest in learning these skills. Lack of training in EBM, journal club presentation and analytical reading skills have limited the impact of upgraded technology in enhancing the level of knowledge. This impact can be boosted by developing a curriculum with skills necessary in using EBM.

  2. Deriving Fuel Mass by Size Class in Douglas-fir (Pseudotsuga menziesii Using Terrestrial Laser Scanning

    Directory of Open Access Journals (Sweden)

    Lloyd Queen


    Full Text Available Requirements for describing coniferous forests are changing in response to wildfire concerns, bio-energy needs, and climate change interests. At the same time, technology advancements are transforming how forest properties can be measured. Terrestrial Laser Scanning (TLS is yielding promising results for measuring tree biomass parameters that, historically, have required costly destructive sampling and resulted in small sample sizes. Here we investigate whether TLS intensity data can be used to distinguish foliage and small branches (≤0.635 cm diameter; coincident with the one-hour timelag fuel size class from larger branchwood (>0.635 cm in Douglas-fir (Pseudotsuga menziesii branch specimens. We also consider the use of laser density for predicting biomass by size class. Measurements are addressed across multiple ranges and scan angles. Results show TLS capable of distinguishing fine fuels from branches at a threshold of one standard deviation above mean intensity. Additionally, the relationship between return density and biomass is linear by fuel type for fine fuels (r2 = 0.898; SE 22.7% and branchwood (r2 = 0.937; SE 28.9%, as well as for total mass (r2 = 0.940; SE 25.5%. Intensity decays predictably as scan distances increase; however, the range-intensity relationship is best described by an exponential model rather than 1/d2. Scan angle appears to have no systematic effect on fine fuel discrimination, while some differences are observed in density-mass relationships with changing angles due to shadowing.

  5. 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

  8. Management, morphological, and environmental factors influencing Douglas-fir bark furrows in the Oregon Coast Range (United States)

    Sheridan, Christopher D.; Puettmann, Klaus J.; Huso, Manuela M.P.; Hagar, Joan C.; Falk, Kristen R.


    Many land managers in the Pacific Northwest have the goal of increasing late-successional forest structures. Despite the documented importance of Douglas-fir tree bark structure in forested ecosystems, little is known about factors influencing bark development and how foresters can manage development. This study investigated the relative importance of tree size, growth, environmental factors, and thinning on Douglas-fir bark furrow characteristics in the Oregon Coast Range. Bark furrow depth, area, and bark roughness were measured for Douglas-fir trees in young heavily thinned and unthinned sites and compared to older reference sites. We tested models for relationships between bark furrow response and thinning, tree diameter, diameter growth, and environmental factors. Separately, we compared bark responses measured on trees used by bark-foraging birds with trees with no observed usage. Tree diameter and diameter growth were the most important variables in predicting bark characteristics in young trees. Measured environmental variables were not strongly related to bark characteristics. Bark furrow characteristics in old trees were influenced by tree diameter and surrounding tree densities. Young trees used by bark foragers did not have different bark characteristics than unused trees. Efforts to enhance Douglas-fir bark characteristics should emphasize retention of larger diameter trees' growth enhancement.


    Purportedly, large Douglas-fir trees in the American Pacific Northwest use water stored in bole tissues to ameliorate the effects of seasonal summer drought, the water content of bole tissues being drawn down over the summer months and replenished during the winter. Continuous mo...

  18. A Case of Extragonadal Teratoma in the Pouch of Douglas and Literature Review. (United States)

    Kakuda, Mamoru; Matsuzaki, Shinya; Kobayashi, Eiji; Yoshino, Kiyoshi; Morii, Eiichi; Kimura, Tadashi


    Mature cystic teratoma is a germ cell tumor of the ovaries and is often observed in clinical practice. However, extragonadal teratomas are rare tumors and have been reported outside the ovaries, (e.g., in the greater omentum). The mechanism underlying the development of extragonadal teratomas remains unknown. We encountered a case of extragonadal teratoma in the pouch of Douglas that appeared to be a parasitic dermoid cyst. From our experience and the literature review, we discuss the potential mechanism leading to the development of extragonadal teratomas. A 41-year-old nonpregnant woman was referred to our department due to myoma and anemia. A 4-cm asymptomatic mass in the pouch of Douglas was observed, and the patient was diagnosed with ovarian mature cystic teratoma. She underwent laparoscopic surgery, and intraoperative findings revealed that the fallopian tube was injured and torn, and a residual small ovary was observed in the left side of the ovary. A tumor measuring approximately 4 cm observed in the pouch of Douglas was extracted without rupturing. The tumor was diagnosed as a parasitic dermoid cyst by macroscopic and histopathological findings. Auto-amputation could be the underlying mechanism that leads to an isolated parasitic dermoid cyst in the pouch of Douglas. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

  7. 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.

Photonics-themed active learning activities are conducted in the college Waves and Modern Physics class, helping students forge relationships between course content and modern communications technologies. Presentations on photonics research are prepared and presented by the professor and past college student-researchers. The students are then given a full tour of the photonics university laboratories. Furthermore, funds are set aside to give college students a unique opportunity to assist the college professor with experiments during a paid summer research internship.

  16. Condensates near the Argyres-Douglas point in SU (2) gauge theory with broken Ν = 2 supersymmetry

    International Nuclear Information System (INIS)

    Gorsky, A.


    The behaviour of the chiral condensates in the SU(2) gauge theory with broken N = 2 supersymmetry is reviewed. The calculation of monopole, dyon, and charge condensates is described. It is shown that the monopole and charge condensates vanish at the Argyres-Douglas point where the monopole and charge vacua collide. This phenomenon is interpreted as a deconfinement of electric and magnetic charges at the Argyres-Douglas point. (authors)

  19. 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.

  20. Two-Step Hot-Compressed Water Treatment of Douglas Fir for Efficient Total Sugar Recovery by Enzymatic Hydrolysis

    Directory of Open Access Journals (Sweden)

    Hiroyuki Inoue


    Full Text Available The non-catalytic hydrothermal pretreatment of softwood is generally less effective for subsequent enzymatic hydrolysis. In this study, the efficacy of hot-compressed water (HCW treatment of Douglas fir was investigated between 180 °C and 260 °C, allowing solubilization of the cellulose components. The enzymatic digestibility of cellulosic residues increased significantly under HCW conditions > 250 °C, and the enhanced glucan digestibility was closely related to the decomposition of the cellulose component. Combination of the first-stage HCW treatment (220 °C, 5 min to recover hemicellulosic sugars with the second-stage HCW treatment (260 °C, 5 min to improve cellulose digestibility gave a total sugar recovery of 56.2% based on the dried raw materials. This yield was 1.4 times higher than that from the one-step HCW-treated sample (260 °C, 5 min. Additionally, an enzymatic hydrolysate from the two-step HCW-treated sample exceeded 90% of the ethanol fermentation yield based on the total sugars present in the hydrolysates. These results suggest the potential of the two-step HCW treatment of softwood as a pretreatment technology for efficient total sugar recovery and ethanol production.

  1. 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 represent distinct climate environments in the western United States, we show that increased temperature decreases growth via vapor pressure deficit (VPD) across all latitudes. Using 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.

  2. 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.

  3. Synthetic Biology and the Moral Significance of Artificial Life: A Reply to Douglas, Powell and Savulescu. (United States)

    Christiansen, Andreas


    I discuss the moral significance of artificial life within synthetic biology via a discussion of Douglas, Powell and Savulescu's paper 'Is the creation of artificial life morally significant'. I argue that the definitions of 'artificial life' and of 'moral significance' are too narrow. Douglas, Powell and Savulescu's definition of artificial life does not capture all core projects of synthetic biology or the ethical concerns that have been voiced, and their definition of moral significance fails to take into account the possibility that creating artificial life is conditionally acceptable. Finally, I show how several important objections to synthetic biology are plausibly understood as arguing that creating artificial life in a wide sense is only conditionally acceptable. © 2016 John Wiley & Sons Ltd.

    Baker, W. L.; Veblen, T. T.; Sherriff, R. L.


    Forest restoration in ponderosa pine and mixed ponderosa pine–Douglas fir forests in the US Rocky Mountains has been highly influenced by a historical model of frequent, low-severity surface fires developed for the ponderosa pine forests of the Southwestern USA. A restoration model, based on this low-severity fire model, focuses on thinning and prescribed burning to restore historical forest structure. However, in the US Rocky Mountains, research on fire history and forest structure, and earl...

  15. Minimal Liouville gravity on the torus via the Douglas string equation

    International Nuclear Information System (INIS)

    Spodyneiko, Lev


    In this paper we assume that the partition function in minimal Liouville gravity (MLG) obeys the Douglas string equation. This conjecture makes it possible to compute the torus correlation numbers in (3,p) MLG. We perform this calculation using also the resonance relations between the coupling constants in the KdV frame and in the Liouville frame. We obtain explicit expressions for the torus partition function and for the one- and two-point correlation numbers. (paper)

  1. Competitive relations between Douglas-fir and Pacific madrone on shallow soils in a Mediterranean climate (United States)

    Wang, Zheng Q.; Newton, M.; Tappeiner, J. C.


    A large area of Pacific Coast forests is characterized by shallow soil, with negligible rainfall in the growing season. This study explores water-seeking strategy on such a site. We studied availability of bedrock water and its effects on growth and ecophysiology of 11-yr-old planted Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and sprouting Pacific madrone (Arbutus menziesii Pursh). The study was carried out at three regulated densities of madrone sprouts on shallow ( 0.05) among three densities of madrone. However, cover in plots with the highest density of madrone (1322 sprout clumps/ha) depleted 50 mm of water from the 1.5 m layer by June, whereas vegetation on lower density treatments withdrew 15-28 mm by June, with later withdrawal distributed more uniformly through the growing season. Madrone density significantly affected basal diameter (P a?? 0.0001) and height growth (P a?? 0.002) of Douglas-fir. Madrone was consistently taller than Douglas-fir in all plots. The height of 11-yr-old madrone sprout clumps (424-465 cm) did not differ significantly among densities. Madrone leaf area index and biomass were higher at the high density of madrone than at medium density (P a?? 0.045, LAI; P a?? 0.001, biomass). Physiological advantages and rooting habits of madrone give it a competitive advantage over Douglas-fir in this area that it might not have if bedrock did not provide the principal water reservoir for summer growth.

  8. 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. AshkanHassani [2] exposed Cobb-Douglas Production Functions application in construction schedule crashing and project risk analysis related to the duration of construction projects.

  9. Douglas-fir plantations in Europe: a retrospective test of assisted migration to address climate change. (United States)

    Isaac-Renton, Miriam G; Roberts, David R; Hamann, Andreas; Spiecker, Heinrich


    We evaluate genetic test plantations of North American Douglas-fir provenances in Europe to quantify how tree populations respond when subjected to climate regime shifts, and we examined whether bioclimate envelope models developed for North America to guide assisted migration under climate change can retrospectively predict the success of these provenance transfers to Europe. The meta-analysis is based on long-term growth data of 2800 provenances transferred to 120 European test sites. The model was generally well suited to predict the best performing provenances along north-south gradients in Western Europe, but failed to predict superior performance of coastal North American populations under continental climate conditions in Eastern Europe. However, model projections appear appropriate when considering additional information regarding adaptation of Douglas-fir provenances to withstand frost and drought, even though the model partially fails in a validation against growth traits alone. We conclude by applying the partially validated model to climate change scenarios for Europe, demonstrating that climate trends observed over the last three decades warrant changes to current use of Douglas-fir provenances in plantation forestry throughout Western and Central Europe. © 2014 John Wiley & Sons Ltd.

    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.

  7. 'Is she alive? Is she dead?' Representations of chronic disorders of consciousness in Douglas Coupland's Girlfriend in a Coma. (United States)

    Colbeck, Matthew


    Depictions of coma have come to dominate literary and filmic texts over the last half century, a phenomenon coinciding with advancements in medical technology that have led to remarkable increases in the survival rates of patients with chronic disorders of consciousness. Authors of coma fiction are preoccupied with the imagined subjective experience of coma, often creating complex, dream-like worlds from which the protagonist must escape if survival is to be achieved. However, such representations appear to conflict with medical case studies and patient narratives that reveal that most often survivors of coma have no recollection of the coma itself. Providing a close reading of Douglas Coupland's Girlfriend in a Coma (1998) against the context of medical literature and diagnoses, this article examines how the coma patient is represented, often depicting the realities of a prolonged vegetative state, in contrast with other popular representations of coma. It explores how the author develops a work of 'fantastic' fiction (a genre defined by the structuralist critic Tzvetan Todorov), using the condition of coma as a metaphor for a postmodern existential crisis, while simultaneously employing mimetic techniques that raise important medical, ethical and philosophical questions surrounding the ontological status of the comatose patient. It is argued that coma fiction, even in its misrepresentation of the condition, can help us to engage with and interrogate how we think about chronic disorders of consciousness, thereby providing a valuable insight into our attitudes towards illness and mortality.

  10. Non-Douglas-Kazakov phase transition of two-dimensional generalized Yang-Mills theories

    International Nuclear Information System (INIS)

    Khorrami, M.; Alimohammadi, M.


    In two-dimensional Yang-Mills and generalized Yang-Mills theories for large gauge groups, there is a dominant representation determining the thermodynamic limit of the system. This representation is characterized by a density, the value of which should everywhere be between zero and one. This density itself is determined by means of a saddle-point analysis. For some values of the parameter space, this density exceeds one in some places. So one should modify it to obtain an acceptable density. This leads to the well-known Douglas-Kazakov phase transition. In generalized Yang-Mills theories, there are also regions in the parameter space where somewhere this density becomes negative. Here too, one should modify the density so that it remains nonnegative. This leads to another phase transition, different from the Douglas-Kazakov one. Here the general structure of this phase transition is studied, and it is shown that the order of this transition is typically three. Using carefully-chosen parameters, however, it is possible to construct models with the order of the phase transition not equal to three. A class of these non-typical models is also studied. (orig.)

  11. 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.

In this research we have used aggregate production functions of Cobb-Douglas type in different time-series and cross-section analysis of Romania’s economic growth from the standpoint of the intensity of using capital and labour factors, as determinant elements for the level of production and GDP. We have also applied the two factor Constant Elasticity of Substitution (CES production function, which is considered to be the generalised form of the Cobb-Douglas function. Using the available statistical data regarding Romania’s economy in the 1990-2005 period, we have performed time-series and cross-section analysis based on the aggregated production functions at the national level.

  14. 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.

  17. 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.

  2. Exact decoupling of the Dirac Hamiltonian. II. The generalized Douglas-Kroll-Hess transformation up to arbitrary order

    International Nuclear Information System (INIS)

    Reiher, Markus; Wolf, Alexander


    In order to achieve exact decoupling of the Dirac Hamiltonian within a unitary transformation scheme, we have discussed in part I of this series that either a purely numerical iterative technique (the Barysz-Sadlej-Snijders method) or a stepwise analytic approach (the Douglas-Kroll-Hess method) are possible. For the evaluation of Douglas-Kroll-Hess Hamiltonians up to a pre-defined order it was shown that a symbolic scheme has to be employed. In this work, an algorithm for this analytic derivation of Douglas-Kroll-Hess Hamiltonians up to any arbitrary order in the external potential is presented. We discuss how an estimate for the necessary order for exact decoupling (within machine precision) for a given system can be determined from the convergence behavior of the Douglas-Kroll-Hess expansion prior to a quantum chemical calculation. Once this maximum order has been accomplished, the spectrum of the positive-energy part of the decoupled Hamiltonian, e.g., for electronic bound states, cannot be distinguished from the corresponding part of the spectrum of the Dirac operator. An efficient scalar-relativistic implementation of the symbolic operations for the evaluation of the positive-energy part of the block-diagonal Hamiltonian is presented, and its accuracy is tested for ground-state energies of one-electron ions over the whole periodic table. Furthermore, the first many-electron calculations employing sixth up to fourteenth order DKH Hamiltonians are presented

  16. Regional patterns of increasing Swiss needle cast impacts on Douglas-fir growth with warming temperatures. (United States)

    Lee, E Henry; Beedlow, Peter A; Waschmann, Ronald S; Tingey, David T; Cline, Steven; Bollman, Michael; Wickham, Charlotte; Carlile, Cailie


    The fungal pathogen, Phaeocryptopus gaeumannii , causing Swiss needle cast (SNC) occurs wherever Douglas-fir is found but disease damage is believed to be limited in the U.S. Pacific Northwest (PNW) to the Coast Range of Oregon and Washington (Hansen et al., Plant Disease , 2000, 84 , 773; Rosso & Hansen, Phytopathology , 2003, 93 , 790; Shaw, et al., Journal of Forestry , 2011, 109 , 109). However, knowledge remains limited on the history and spatial distribution of SNC impacts in the PNW. We reconstructed the history of SNC impacts on mature Douglas-fir trees based on tree-ring width chronologies from western Oregon. Our findings show that SNC impacts on growth occur wherever Douglas-fir is found and is not limited to the coastal fog zone. The spatiotemporal patterns of growth impact from SNC disease were synchronous across the region, displayed periodicities of 12-40 years, and strongly correlated with winter and summer temperatures and summer precipitation. The primary climatic factor limiting pathogen dynamics varied spatially by location, topography, and elevation. SNC impacts were least severe in the first half of the 20th century when climatic conditions during the warm phase of the Pacific Decadal Oscillation (1924-1945) were less conducive to pathogen development. At low- to mid-elevations, SNC impacts were most severe in 1984-1986 following several decades of warmer winters and cooler, wetter summers including a high summer precipitation anomaly in 1983. At high elevations on the west slope of the Cascade Range, SNC impacts peaked several years later and were the greatest in the 1990s, a period of warmer winter temperatures. Climate change is predicted to result in warmer winters and will likely continue to increase SNC severity at higher elevations, north along the coast from northern Oregon to British Columbia, and inland where low winter temperatures currently limit growth of the pathogen. Our findings indicate that SNC may become a significant

  1. 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.

  2. VizieR Online Data Catalog: Praesepe members rotational periods from K2 LCs (Douglas+, 2017) (United States)

    Douglas, S. T.; Agueros, M. A.; Covey, K. R.; Kraus, A.


    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).

  3. Measurement and analysis of pressure tube elongation in the Douglas Point reactor

    Causey, A.R.; MacEwan, S.R.; Jamieson, H.C.; Mitchell, A.B.


    Elongations of zirconium alloy pressure tubes in CANDU reactors, which occur as a result of neutron-irradiation-induced creep and growth, have been measured over the past 6 years, and the consequences of thses elongations have recently been analysed. Elongation rates, previously deduced from extensive measurements of elongations of cold-worked Zircaloy-2 pressure tubes in the Pickering reactors, have been modified to apply to the pressure tubes in the Douglas Point (DP) reactor by taking into account measured diffences in texture and dislocation density. Using these elongation rates, and structural data unique to the DP reactor, the analysis predicts elongation behaviour which is in good agreement with pressure tube elongations measured during the ten years of reactor operation.

  4. Impact of energy efficiency gains on output and energy use with Cobb-Douglas production function

    International Nuclear Information System (INIS)

    Wei Taoyuan


    A special issue of Energy Policy-28 (2000)-was devoted to a collection of papers, edited by Dr. Lee Schipper. The collection included a paper entitled 'A view from the macro side: rebound, backfire, and Khazzoom-Brookes' in which it was argued that the impact of fuel efficiency gains on output (roughly, GDP) is likely to be relatively small by Cobb-Douglas production function. However, an error in the analysis leads to under-estimation of the long-term impact. This paper first provides a partial equilibrium analysis by an alternative method for the same case and then proceeds to an analysis on the issue in a two-sector general equilibrium system. In the latter analysis, energy price is internalized. Both energy use efficiency and energy production efficiency are involved

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

    Gaiotto, D. [Institute for Advanced Study (IAS), Princeton, NJ (United States); Teschner, J. [Deutsches Elektronen-Synchrotron (DESY), Hamburg (Germany)


    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{sup 4}. (orig.)

  6. Age-related variation in genetic control of height growth in Douglas-fir. (United States)

    Namkoong, G; Usanis, R A; Silen, R R


    The development of genetic variances in height growth of Douglas-fir over a 53-year period is analyzed and found to fall into three periods. In the juvenile period, variances in environmental error increase logarithmically, genetic variance within populations exists at moderate levels, and variance among populations is low but increasing. In the early reproductive period, the response to environmental sources of error variance is restricted, genetic variance within populations disappears, and populational differences strongly emerge but do not increase as expected. In the later period, environmental error again increases rapidly, but genetic variance within populations does not reappear and population differences are maintained at about the same level as established in the early reproductive period. The change between the juvenile and early reproductive periods is perhaps associated with the onset of ecological dominance and significant allocations of energy to reproduction.

  8. 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

  9. Investigating the factors effective on the acquaintance with and use of Information and Communication Technology (ICT in organizational responsibilities of the faculty members of the College of Agriculture and Natural Resources, University of Tehran

    Yeganeh Madadi


    Full Text Available Nowadays it is very unlikely to come across an organization in which Information and Communication Technology is not discussed and hasn't become one of the apprehensions of the organizational managers.To insure an effective competitive edge in educational organizations, universities from all across the world must consistently improve their Information and Communication Technology.The purpose of this research was to investigate the amount of knowledge and use of Information and Communication Technology by employees. Information gathering was done by developing a questionnaire. The population of interest consisted of all the faculty members of the College of Agriculture and Natural Resources, University of Tehran, and a random group of 124 members were selected for statistical analysis. The validity of the questionnaire was approved by the statistics professionals and the foundation of it was approved by calculating the Cronbach’s alpha to 0/95.The results show that the degree of ICT use is directly and positively proportional to the educational degrees and academic ranking, and negatively proportional to work experience, and showed no correlation to age.The results of mean analysis showed a difference between the amount of usage of and familiarity with ICT between men and women and the variance analysis results showed that the amount of familiarity with and usage of ICT is different between different levels of education, academic ranks and different types of employment. Finally the results of regression analysis showed that the three variables of level of education, type of employment and age had a meaningful effect on the dependent variable of amount of familiarity with ICT, and the three variables of familiarity, type of employment and gender had a meaningful effect on the dependent variable of amount of usage of ICT. In general increasing the amount of familiarity with ICT is the most important factor effecting organization usage.

  12. Sixth-order Douglas-Kroll: two-component reference data for one-electron ions from 1s12 through 4f72

    International Nuclear Information System (INIS)

    Wuellen, Christoph van


    Quasirelativistic Douglas-Kroll calculations including spin-orbit interaction have been performed for hydrogen-like (one-electron) ions. The Douglas-Kroll operators have been implemented up to the sixth order, and a huge even-tempered basis set has been applied that gives results to microhartree accuracy for the energy levels 1s 12 through 4f 72 for all ions with nuclear charge from Z=1 up to Z=100. Besides providing reference data for other implementations, these results can be used to analyse the performance of the Douglas-Kroll method. Such an analysis is presented for the 1s energy levels and the spin-orbit splitting of the 2p shell. The leading order of the error of the Douglas-Kroll result is different for 2s and 2p 12 although these levels are degenerate both at nonrelativistic and Dirac level

    Information technology (IT) is widely used in medical education. However, there are not enough studies about IT uses and preferences among traditional and problem-based learning (PBL) medical students. To compare IT skills, uses and preferences for education between traditional and PBL medical students'. A cross-sectional study; a modified Educause Center for Analysis and Research online survey was sent to traditional curriculum 5th and PBL 4th year medical students of King Saud University. Most of the responding 176 students prefer mobile devices and moderate amount of IT in education. Fourth and fifth year students perceived high academic value of Google (94.2 vs. 86.7%, p = 0.34), YouTube (90.7 vs. 92.2%, p = 0.83) and PubMed (83.7 vs. 86.7%, p = 0.06). More 4th year than 5th year students rated themselves as skilled in learning management system (54.7 vs. 21.1%, p = 0.0001) and Smartboard use (40.7 vs. 23.3%, p = 0.04). Most students rated faculty IT skills as effective. Students agreed that technology helps working faster (95.5%) and make learning creative (85.9%). More integration of information literacy and IT training in medical curricula is needed to enhance better utilization of full features of IT resources available for learning and problem solving. National multi-institutional studies are recommended.

  18. Fourth order Douglas implicit scheme for solving three dimension reaction diffusion equation with non-linear source term

    Directory of Open Access Journals (Sweden)

    Shahid Hasnain


    Full Text Available This research paper represents a numerical approximation to non-linear three dimension reaction diffusion equation with non-linear source term from population genetics. Since various initial and boundary value problems exist in three dimension reaction diffusion phenomena, which are studied numerically by different numerical methods, here we use finite difference schemes (Alternating Direction Implicit and Fourth Order Douglas Implicit to approximate the solution. Accuracy is studied in term of L2, L∞ and relative error norms by random selected grids along time levels for comparison with analytical results. The test example demonstrates the accuracy, efficiency and versatility of the proposed schemes. Numerical results showed that Fourth Order Douglas Implicit scheme is very efficient and reliable for solving 3-D non-linear reaction diffusion equation.

  19. Deconfinement at the Argyres-Douglas point in SU(2) gauge theory with broken N=2 supersymmetry

    International Nuclear Information System (INIS)

    Gorsky, A.; Vainshtein, A.; Yung, A.


    We consider chiral condensates in SU(2) gauge theory with broken N=2 supersymmetry. The matter sector contains an adjoint multiplet and one fundamental flavor. Matter and gaugino condensates are determined by integrating out the adjoint field. The only nonperturbative input is the Affleck-Dine-Seiberg (ADS) superpotential generated by one instanton plus the Konishi anomaly. These results are consistent with those obtained by the 'integrating in' procedure, including a reproduction of the Seiberg-Witten curve from the ADS superpotential. We then calculate monopole, dyon, and charge condensates using the Seiberg-Witten approach. We show that the monopole and charge condensates vanish at the Argyres-Douglas point where the monopole and charge vacua collide. We interpret this phenomenon as a deconfinement of electric and magnetic charges at the Argyres-Douglas point

    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.

  3. Foliar nitrogen metabolism of adult Douglas-fir trees is affected by soil water availability and varies little among provenances. (United States)

    The coniferous forest tree Douglas-fir (Pseudotsuga menziesii) is native to the pacific North America, and is increasingly planted in temperate regions worldwide. Nitrogen (N) metabolism is of great importance for growth, resistance and resilience of trees. In the present study, foliar N metabolism of adult trees of three coastal and one interior provenance of Douglas-fir grown at two common gardens in southwestern Germany (Wiesloch, W; Schluchsee, S) were characterized in two subsequent years. Both the native North American habitats of the seed sources and the common garden sites in Germany differ in climate conditions. Total and mineral soil N as well as soil water content were higher in S compared to W. We hypothesized that i) provenances differ constitutively in N pool sizes and composition, ii) N pools are affected by environmental conditions, and iii) that effects of environmental factors on N pools differ among interior and coastal provenances. Soil water content strongly affected the concentrations of total N, soluble protein, total amino acids (TAA), arginine and glutamate. Foliar concentrations of total N, soluble protein, structural N and TAA of trees grown at W were much higher than in trees at S. Provenance effects were small but significant for total N and soluble protein content (interior provenance showed lowest concentrations), as well as arginine, asparagine and glutamate. Our data suggest that needle N status of adult Douglas-fir is independent from soil N availability and that low soil water availability induces a re-allocation of N from structural N to metabolic N pools. Small provenance effects on N pools suggest that local adaptation of Douglas-fir is not dominated by N conditions at the native habitats.

  8. Five-Year Impacts of Swiss Needle Cast on Douglas-fir in Interior Forests of Oregon, USA

    Directory of Open Access Journals (Sweden)

    FILIP, Gregory


    Full Text Available In 2001 and 2006, we examined 590 Douglas-firs in 59 stands age 10-23 years in the northern Cascade Mountain foothills in Oregon, USA. Mean 5-year-dbh growth was 6.1 cm and total-height growth was 3.6 m. Mean needle-retention index increased by 3.4 over 5 years, and mid-crown retention increased by 1.2 years. Mean percentages of stomata occluded by pseudothecia of Phaeocryptopus gaeumannii were 13.6% for 2000-(2-year-old needles and 1.7% for 2001-(1-year-old needles sampled in 2002, and 13.3% for 2004 (2-year-old needles sampled in 2006. Mean crown-length to sapwood-area ratio was 5.2 cm/cm2 in 2006. There were poor correlations (R2 <0.3 among all variables except for a moderate correlation between stand elevation and either 2000-stomata occluded (R2 = 0.43 or 2004-stomata occluded (R2 = 0.50, where there were fewer pseudothecia at the higher elevations. Either 5 years is not enough time to evaluate the affects of Swiss needle cast on Douglas-fir growth in the Oregon Cascades or there was no significant effect of Swiss needle cast during the latest outbreak on Douglas-fir growth. Based on our results and their interpretation, forest managers may need not alter their current practices in the northern Oregon Cascades, and managing a mix of Douglas-fir and western hemlock at lower elevations and noble fir at higher elevations will help offset any future stand-growth declines due to Swiss needle cast.

  14. Seasonal carbohydrate dynamics and growth in Douglas-fir trees experiencing chronic, fungal-mediated reduction in functional leaf area. (United States)

    Saffell, Brandy J; Meinzer, Frederick C; Woodruff, David R; Shaw, David C; Voelker, Steven L; Lachenbruch, Barbara; Falk, Kristen


    Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which NSCs can be mobilized under natural conditions of low water stress and restricted carbon supply in relation to potential demands for growth. We analyzed the concentrations of starch, sucrose, glucose and fructose in foliage, twig wood and trunk sapwood of 15 co-occurring Douglas-fir trees expressing a gradient of Swiss needle cast symptom severity quantified as previous-year functional foliage mass. Growth (mean basal area increment, BAI) decreased by ∼80% and trunk NSC concentration decreased by 60% with decreasing functional foliage mass. The ratio of relative changes in NSC concentration and BAI, an index of the relative priority of storage versus growth, more than doubled with increasing disease severity. In contrast, twig and foliage NSC concentrations remained nearly constant with decreasing functional foliage mass. These results suggest that under disease-induced reductions in carbon supply, Douglas-fir trees retain NSCs (either actively or due to sequestration) at the expense of trunk radial growth. The crown retains the highest concentrations of NSC, presumably to maintain foliage growth and shoot extension in the spring, partially compensating for rapid foliage loss in the summer and fall.
