    The Alpbach Summer School is a ten-day program that provides a unique opportunity for young european science and engineering students, both undergraduate and graduate, to learn how to approach the entire design process of a space mission. The theme of the 2010 Summer School was "New Space Missions to Understand Climate Change", a current, challenging, very broad and complex topic. The program was established more than 35 years ago and is organised in two interrelated parts: a series of lectures held by renowned experts in the field (in the case of this specific year, climate change and space engineering experts) that provides a technical and scientific background for the workshops that follow, the core of the Summer School. For the workshops the students are split into four international, interdisciplinary teams of about 15 students. In 2010 every team had to complete a number of tasks, four in total: (1) identify climate change research gaps and design a space mission that has not yet been flown or proposed, (2) define the science objectives and requirements of the mission, (3) design a spacecraft that meets the mission requirements, which includes spacecraft design and construction, payload definition, orbit calculations, but also the satellite launch, operation and mission costs and (4) write up a short mission proposal and present the results to an expert review panel. Achieving these tasks in only a few days in a multicultural, interdisciplinary team represents a major challenge for all participants and provides an excellent practical learning experience. Over the course of the program, students do not just learn facts about climate change and space engineering, but scientists also learn from engineers and engineers from scientists. The participants have to deepen their knowledge in an often unfamiliar field, develop organisational and team-work skills and work under pressure. Moreover, teams are supported by team and roving tutors and get the opportunity to

  3. How business schools lost their way.

    Bennis, Warren G; O'Toole, James

    2005-05-01

    Business schools are facing intense criticism for failing to impart useful skills, failing to prepare leaders, failing to instill norms of ethical behavior--and even failing to lead graduates to good corporate jobs. These criticisms come not just from students, employers, and the media but also from deans of some of America's most prestigious B schools. The root cause oftoday's crisis in management education, assert Warren G. Bennis and James O'Toole, is that business schools have adopted an inappropriate--and ultimately self-defeating--model of academic excellence. Instead of measuring themselves in terms of the competence of their graduates, or by how well their faculty members understand important drivers of business performance, they assess themselves almost solely by the rigor of their scientific research. This scientific model is predicated on the faulty assumption that business is an academic discipline like chemistry or geology when, in fact, business is a profession and business schools are professional schools--or should be. Business school deans may claim that their schools remain focused on practice, but they nevertheless hire and promote research-oriented professors who haven't spent time working in companies and are more comfortable teaching methodology than messy, multidisciplinary issues--the very stuff of management. The authors don't advocate a return to the days when business schools were glorified trade schools. But to regain relevancy, they say, business schools must rediscover the practice of business and find a way to balance the dual mission of educating practitioners and creating knowledge through research.

  8. Definition and detection of data-based uniqueness in evaluating bilinear (two-way) chemical measurements.

    2015-01-15

    Multivariate curve resolution methods, frequently used in analyzing bilinear data sets, result in ambiguous decomposition in general. Implementing the adequate constraints may lead to reduce the so-called rotational ambiguity drastically, and in the most favorable cases to the unique solution. However, in some special cases, non-negativity constraint as minimal information of the system is a sufficient condition to resolve profiles uniquely. Although, several studies on exploring the uniqueness of the bilinear non-negatively constrained multivariate curve resolution methods have been made in the literature, it has still remained a mysterious question. In 1995, Manne published his profile-based theorems giving the necessary and sufficient conditions of the unique resolution. In this study, a new term, i.e., data-based uniqueness is defined and investigated in details, and a general procedure is suggested for detection of uniquely recovered profile(s) on the basis of data set structure in the abstract space. Close inspection of Borgen plots of these data sets leads to realize the comprehensive information of local rank, and these argumentations furnish a basis for data-based uniqueness theorem. The reported phenomenon and its exploration is a new stage (it can be said fundament) in understanding and describing the bilinear (matrix-type) chemical data in general. Our proposed detection tool is restricted to three-component systems because of the visual limitations of the Borgen plot, but the theorem is universal for systems with more than three components. A recently published experimental four-component system is used for illustrating this theorem in the case of systems with more than three components.

  11. Choosing school underachievement as a way to resist power

    Directory of Open Access Journals (Sweden)

    Džinović Vladimir

    2006-01-01

    Full Text Available Underachievement in school is seen as a failure in traditional theories of education. An alternative construction of school underachievement, from the point of view of Michel Foucault’ s approach to power and George Kelly's principle of elaborative choice, is offered as the subject matter of this paper. Instead of being construed exclusively as a measure of good education school success can be seen as the effect of normalization based on the power of discourses dominating in a society. In the same time, underachievement can be seen as a form of resistance to dominant discourse, as well as a way of defining identity in accordance with marginalized discourses whose significance is not recognized or respected from the point of school authorities. The prevailing tradition of European rationality treats poor achievement as a case of norm deviation. The individual perspectives are discounted as irrational and disordered behavior, requiring treatment. Kelly however, asserts that claims of irrationality reflect poor understanding of individual perspectives. When individuals resist the dominant discourse and underachieve despite their abilities, they are making an active choice which should be understood from their point of view. The choice someone makes is always an elaborative choice. Thus underachievement may be construed as resistance to power, based on the principle of elaborative choice.

    Erne, Cordula; Elfering, Achim

    2011-12-01

    Psychosocial stress and pain may relate to educational selection. At the end of primary school (International Standard Classification of Education: ISCED level 1) children are recommended for one of three performance-based lower secondary level types of school (ISCED level 2). The study examines the association of educational selection and other risk factors with pain in the upper back (UBP), lower back pain (LBP), peripheral (limb) pain (PP), and abdominal pain (AP). Teacher reports of unsatisfactory grades in mathematics, and official school-type recommendation are included as objective psychosocial risk factors. One hundred and ninety-two schoolchildren, aged between 10 and 13 from 11 classes of 7 schools in Switzerland participated in the cross-sectional study. In logistic regression analysis, predictor variables included age, sex, BMI, participation in sport, physical mobility, weight of satchel, hours of daily TV, video, and computer use, pupils' back pain reported by the mother and father, psychosocial strain, unsatisfactory grade in mathematics, and school-type recommendation. Analysis of pain drawings was highly reliable and revealed high prevalence rates of musculoskeletal pain in the last 4 weeks (UBP 15.3%, LBP 13:8%, PP 33.9%, AP 20.1%). Psychosocial risk factors were uniquely significant predictors of UBP (psychosocial strain), LBP (psychosocial strain, unsatisfactory grade in mathematics, school-type recommendation), and AP (school-type recommendation). In conclusion, selection in terms of educational school system was uniquely associated with LBP in schoolchildren. Stress caused by educational selection should be addressed in primary prevention of musculoskeletal pain in schoolchildren.

  3. A New Way of Using the Interactive Whiteboard in a High School Physics Classroom: A Case Study

    Science.gov (United States)

    Gregorcic, Bor; Etkina, Eugenia; Planinsic, Gorazd

    2017-02-01

    In recent decades, the interactive whiteboard (IWB) has become a relatively common educational tool in Western schools. The IWB is essentially a large touch screen, that enables the user to interact with digital content in ways that are not possible with an ordinary computer-projector-canvas setup. However, the unique possibilities of IWBs are rarely leveraged to enhance teaching and learning beyond the primary school level. This is particularly noticeable in high school physics. We describe how a high school physics teacher learned to use an IWB in a new way, how she planned and implemented a lesson on the topic of orbital motion of planets, and what tensions arose in the process. We used an ethnographic approach to account for the teacher's and involved students' perspectives throughout the process of teacher preparation, lesson planning, and the implementation of the lesson. To interpret the data, we used the conceptual framework of activity theory. We found that an entrenched culture of traditional white/blackboard use in physics instruction interferes with more technologically innovative and more student-centered instructional approaches that leverage the IWB's unique instructional potential. Furthermore, we found that the teacher's confidence in the mastery of the IWB plays a crucial role in the teacher's willingness to transfer agency within the lesson to the students.

  7. Cognitive, Parent and Teacher Rating Measures of Executive Functioning: Shared and Unique Influences on School Achievement.

    Science.gov (United States)

    Dekker, Marielle C; Ziermans, Tim B; Spruijt, Andrea M; Swaab, Hanna

    2017-01-01

    Very little is known about the relative influence of cognitive performance-based executive functioning (EF) measures and behavioral EF ratings in explaining differences in children's school achievement. This study examined the shared and unique influence of these different EF measures on math and spelling outcome for a sample of 84 first and second graders. Parents and teachers completed the Behavior Rating Inventory of Executive Function (BRIEF), and children were tested with computer-based performance tests from the Amsterdam Neuropsychological Tasks (ANT). Mixed-model hierarchical regression analyses, including intelligence level and age, showed that cognitive performance and teacher's ratings of working memory and shifting concurrently explained differences in spelling. However, teacher's behavioral EF ratings did not explain any additional variance in math outcome above cognitive EF performance. Parent's behavioral EF ratings did not add any unique information for either outcome measure. This study provides support for the ecological validity of performance- and teacher rating-based EF measures, and shows that both measures could have a complementary role in identifying EF processes underlying spelling achievement problems. The early identification of strengths and weaknesses of a child's working memory and shifting capabilities, might help teachers to broaden their range of remedial intervention options to optimize school achievement.

  10. The Ratio of Retrograde to Prograde Orbits: A Unique Way to test Kuiper Belt Binary Formation Theories

    CERN Document Server

    Schlichting, Hilke E

    2008-01-01

    With the discovery of Kuiper Belt binaries that have wide separations and roughly equal masses new theories were proposed to explain their formation. Two formation scenarios were suggested by Goldreich and collaborators: In the first, dynamical friction that is generated by the sea of small bodies enables a transient binary to become bound ($L^2s$ mechanism); in the second, a transient binary gets bound by an encounter with a third body ($L^3$ mechanism). We show that these different binary formation scenarios leave their own unique signatures in the relative abundance of prograde to retrograde binary orbits. This signature is due to stable retrograde orbits that exist much further out in the Hill sphere than prograde orbits. It provides an excellent opportunity to distinguish between the different binary formation scenarios observationally. We predict that if binary formation proceeded while sub-Hill velocities prevailed, the vast majority of all comparable mass ratio binaries have retrograde orbits. This do...

  1. Advanced Energy Retrofit Guide: Practical Ways to Improve Energy Performance, K-12 Schools (Book)

    Energy Technology Data Exchange (ETDEWEB)

    2013-12-01

    The U.S. Department of Energy developed the Advanced Energy Retrofit Guides (AERGs) to provide specific methodologies, information, and guidance to help energy managers and other stakeholders plan and execute energy efficiency improvements. Detailed technical discussion is fairly limited. Instead, we emphasize actionable information, practical methodologies, diverse case studies, and unbiased evaluations of the most promising retrofit energy efficiency measures for each building type. A series of AERGs is under development, addressing key segments of the commercial building stock. K-12 schools were selected as one of the highest priority building sectors, because schools affect the lives of most Americans. They also represent approximately 8% of the energy use and 10% of the floor area in commercial buildings nationwide. U.S. K-12 school districts spend more than $8 billion each year on energy - more than they spend on computers and textbooks combined. Most occupy older buildings that often have poor operational performance - more than 30% of schools were built before 1960. The average age of a school is about 42 years - which is nearly the expected serviceable lifespan of the building. K-12 schools offer unique opportunities for deep, cost-effective energy efficiency improvements, and this guide provides convenient and practical guidance for exploiting these opportunities in the context of public, private, and parochial schools.

    Although our country has attached great importance to English education, especially to the senior high schools ’Eng-lish teaching and learning, there still exist a great number of senior high school students who can ’t learn English well. Low learn-ing motivation is one of the major causes. Thus, it is urgent to improve the senior high school students ’English learning motiva-tion in the present English education process. In this paper, starting with the definition of learning motivation, and based on attri-bution theory, need theory, the author will roughly discuss the internal factors and external factors, which lead to the senior high school students’low English learning motivation, and then analyze the possible ways to motivate the students to learn English.

  4. Acoustic and social design of schools-ways to improve the school listening environment

    Results of noise research indicate that communication, and as a result, teaching, learning and the social atmosphere are impeded by noise in schools. The development of strategies to reduce noise levels has often not been effective. A more promising approach seems to be to pro-actively support the ability to listen and to understand. The presentation describes the approach to an acoustic and social school design developed and explored within the project ``GanzOhrSein'' by the Education Department of the Ludwig-Maximilians-University of Munich. The scope includes an analysis of the current ``school soundscape,'' an introduction to the concept of the project to improve individual listening abilities and the conditions for listening, as well as practical examples and relevant research results. We conclude that an acoustic school design should combine acoustic changes in classrooms with educational activities to support listening at schools and thus contribute to improving individual learning conditions and to reducing stress on both pupils and teachers.

  6. The Ultraviolet Sky: final catalogs of unique UV sources from GALEX, and characterization of the UV-emitting sources across the sky, and of the Milky Way extinction

    The legacy of the Galaxy Evolution Explorer (GALEX), which imaged the sky at Ultraviolet (UV) wavelengths for about 9 years, is its unprecedented database with more than 200 million source measurements in far-UV (FUV) and near-UV (NUV), as well as wide-field imaging of extended objects. GALEX's data, the first substantial sky surveys at UV wavelengths, offer an unprecedented view of the sky and a unique opportunity for an unbiased characterization of several classes of astrophysical objects, such as hot stars, QSOs at red-shift about 1, UV-peculiar QSOs, star-forming galaxies, among others. Bianchi et al. (2013, J. Adv. Space Res. (2013), DOI: http://dx.doi.org/10.1016/j.asr.2013.07.045) have constructed final catalogs of UV sources, with homogeneous quality, eliminating duplicate measurements of the same source ('unique' source catalogs), and excluding rim artifacts and bad photometry. The catalogs are constructed improving on the recipe of Bianchi et al. 2011 (MNRAS, 411, 2770, which presented the earlier version of these catalogs) and include all data for the major surveys, AIS and MIS. Considering the fields where both FUV and NUV detectors were exposed, the catalogs contain about 71 and 16.6 million unique sources respectively. We show several maps illustrating the content of UV sources across the sky, globally, and separately for bright/faint, hot, stellar/extragalactic objects. We matched the UV-source catalogs with optical-IR data from the SDSS, GSC2, 2MASS surveys. We are also in the process of matching the catalogs with preliminary PanSTARRS1 (PS1) 3pi survey photometry which already provides twice the sky coverage of SDSS, at slightly fainter magnitude limits. The sources' SED from FUV to optical wavelengths enables classification, derivation of the object physical parameters, and ultimately also a map of the Milky Way extinction. The catalogs will be available on MAST, Vizier (where the previous version already is), and in reduced form (for agile

  7. Unique and interactive effects of empathy, family, and school factors on early adolescents' aggression.

    Although research indicates that empathy inhibits youth aggression, little is known about the prospective associations between different components of empathy and aggression, as well as whether family and school factors moderate the aforementioned associations in early adolescents. Based on prior research, the current study examined whether empathic concern and perspective taking would contribute to subsequent overt and relational aggression over a 1-year period in middle school. Guided by the social development model, we also examined if positive family relations and school connectedness would differentially moderate the associations between both components of empathy and aggression. Participants were 481 10- to 14-year old students (54 % female; 78 % European American) who completed the first wave of a survey in 6th and 7th grades. Hierarchical regression analyses indicated that only for girls did lower levels of empathic concern, not perspective taking, contribute to increases in subsequent overt, not relational, aggression. Although neither positive family relations nor school connectedness played protective roles for girls, results indicated that boys' reports of positive family relations buffered the negative impact of low empathic concern on both forms of aggression 1 year later. Over and above the two components of empathy, school connectedness also contributed to a decline in boys' subsequent overt aggression. Recommendations are made to foster family and school relationships among boys, as well as to more heavily consider the role of emotion processes in the study and prevention of early adolescents' aggression.

  11. Which Way with Informatics in High Schools in the Netherlands? The Dutch Dilemma

    Directory of Open Access Journals (Sweden)

    Nico van DIEPEN

    2011-04-01

    Full Text Available Informatics is currently being taught in high schools all over the world. In the Dutch curriculum, computer literacy is taught in the lower grades as a compulsory subject, Informatics is taught as an elective in the higher grades of some schools. As a follow-up to the outline of Grgurina and Tolboom (2008, the discussion about the future of Informatics education in the Netherlands is investigated and elaborated in this paper. Our research brings forward four positions of the stakeholders in the field: the negative-critical view, the positive-realistic view, the no-nonsense view and the innovative view. Extreme positions are either `to terminate the school subject, because teachers are not qualified and there is little relation with Informatics as a scientific discipline', or `to strengthen the school subject because of its social relevance'. The latter position will be substantiated by a discussion of the novice-expert approach for teaching and the importance of enculturation and situated learning. As a way to strengthen secondary Informatics teaching, especially in the Netherlands, Schoenfeld's framework is advised (Schoenfeld, 2010.

    2015-12-01

    Full Text Available Transition Year is a unique and exciting programme situated in the middle of the six year second level education system in Ireland. Since its introduction in 1974, the programme has experienced unprecedented growth now being offered in over 80% of schools on the island. Transition Year seeks to emphasize alternative learning methodologies including self-directed learning and experiential learning; intellectual, social and personal development; community and inter-school communications; exposure to careers education and the world of work. The latter occurs predominantly through actual work experience. This paper situates and explains the Transition Year Programme in Irish education as well as outlining the significance of the essential work experience component. Transition Year work experience is the bridge that connects young people in the classroom with adult life and the world of work.

  15. The image in the visual arts. New ways of communications at school

    Directory of Open Access Journals (Sweden)

    Flor Ángela Gutiérrez Castro

    2015-07-01

    Full Text Available This is a reflexive article which explains other possibilities and acknowledgements to the use of the visual image in the new ways of communication used at school, through the development of some strategies of action related to the contemplation and the image production: first, negotiate the tendency to the images transmission as a transparent reflecting suggested reality; secondly, to go beyond the interpretation of the images in terms of the negative or positive; and finally, to consider the importance of visual arts in school in the construction of the individual. Based on this reflection some essential concepts are developed about the image as a component of subjectivity since distinctive features that reveal more about its content rather than its definition. The article concludes by outlining the need to build new pedagogical practices, in which beyond promoting the compliance of established academic programs other conditions are built to understand the image as a comprehensible occurrence through the cultural visual-visual arts relationship.

    Full Text Available The objective is to characterize the possible and invented ways and (re invented to provide teacher / to multigrade classes in rural Lomba Grande neighborhood of Novo Hamburgo/RS from 1940 to 1950. This is a study of history of education, and that relies on documentary analysis and narrative records of teachers whose teaching career has been developed in public schools. From the 1940s there was an increase in the number of schools in the city of Novo Hamburgo, effect of rural depopulation and political context of the period, especially in areas of German colonization. Throughout the analysis from the perspective of cultural history is evident in the appearance of the acquired knowledge in practice in everyday routines and cultural experiences accumulated by the subjects. Teachers who have drawn remember example of his teachers to plan and conduct their classes in the early days of teaching. In this sense, the possible way to be a teacher was to master the minimum knowledge of primary school. Due to the difficulties of getting the teacher to rural areas, the practice of appointing "to teach reading, writing and arithmetic" was a common feature in this place. In addition to the in-service training courses and building a professional culture was consolidated from mediations among the most experienced teachers with those just beginning their careers.

    Suicide with hostile intent encompasses a wide range of behaviors, from self-killing by methods that can harm others, to the suicide that generally follows a spree-killing raid. Reports on school shooting, a highly dangerous and lethal behavior that is spreading from North America to European countries, are analyzed within the paradigm of suicide with hostile intent, with the purpose of discovering some elements that might prevent and limit the dissemination of this behavior by imitation. In school shooting, the perpetrators often register a message before their killing raid, as in an ancient form of suicidal assault, the devotio, that was widespread across ancient Mediterranean Roman, Greek, and Hebrew cultures. The development of a code of rules to report on these episodes, likely to attract the interest of the population for their bloody implications, could prevent the dissemination of cultural norms that encourage this behavior.

    Non-specific back pain in children and adolescents has a high prevalence. The aim of this study is to show a Juvenile Back School (JBS) programme and its results in our hospital. A total of 139 patients referred to a Juvenile Back School for advice due to of pain, deformity or back asymmetry were included in a prospective observational study. age, gender, pain, correct postures, sports activities, adherence to JBS and appreciation of these parameters by their parents. VARIABLES were measured with a numerical pain scale and with a survey completed in the first session and 3 months after finishing the JBS. A total of 119 patients finished the study (78 female and 41 male).The average was 13.97±2.29 years (9-20). Three months after JBS, the median pain intensity was reduced from 3 to 0 (P<.0001). There was an improvement in patient postures from 21% to 83% (P<.0001). Patients did not increase their sport activity after the JBS, although its regular practice was linked with pain improvement after JBS (P<.02).Performing exercises did not lead to a decrease in pain. There was a poor correlation between parents and children in the evaluation of post-JBS pain. A back school programme could probably contribute to reduce non-specific back pain and improve postural behaviour in young people. Copyright © 2012 Asociación Española de Pediatría.

    The present study tested whether a close relationship with the teacher would reduce, or a conflictual relationship would amplify, links between peer victimization and school maladjustment. Data on 352 3rd- and 4th-grade children (166 boys; 186 girls) were collected over a two-year period. Teachers provided data on their relationships with students and students' academic performance. Children completed measures assessing peer victimization and school liking. Latent growth curve analyses revealed that at high levels of peer victimization declines in school liking were reduced when student shared a close, low conflict, relationship with their teacher. Furthermore, a combination of peer victimization and poor teacher-child relationship quality predicted trajectories of sustained, low academic performance. These findings highlight the benefits of a close relationship with the teacher for victimized children and the cumulative impact stress within peer- and teacher-relationships can have on students.

    Recent advances in experimental practice, accompanying computational techniques and systems thinking, have advanced biological inquiry. However, current scientific practices do not typically resemble the science taught in schools. As a result, students are missing out on significant opportunities to develop the critical thinking that is needed both in science and many professions. As a potential solution to this ongoing problem in science education, we are using current scientific practices to create classroom activities, packaged in easy-to-use curriculum modules, which promote conceptual development of standards based instructional outcomes. By bringing together students, teachers, researchers, engineers, and programmers we bring needed systems thinking and engaging inquiry experiences to schools throughout Washington State and the nation. Teachers are trained and continuously supported as they learn needed content and methods to bring this new science into their classrooms. Current research on ocean acidification, changing biogeochemical cycles, and the complexity and interdisciplinary nature of ocean systems studies have been translated through our newest curriculum module. Developing this module presented a significant challenge due to the urgency and importance of instilling understanding in high school students as they prepare to make decisions on the highly charged political, economic, and scientific issues of climate change and ocean acidification. Challenges have been overcome through partnerships and through infusing the habits of sustainability, high level thinking, systems modeling, scientific design, and communication. The Next Generation Standards have opened the door for nationwide dissemination of the module as we embark enabling students to think, understand, and contribute to scientific research.

    In the latest decade the safety of the Italian schools against seismic risk is a crucial subject for the Italian legislation as well as to the UN Convention on the DRR and the more specific priorities adopted even within the OECD. Recently, the Italian Parliament approved a law (L98/2013) which launched the Commissioning Safety of School Buildings Plan and the Definition of a Unique Model, to be developed by the CGIAM, in order to improve monitoring network and seismic risk reduction (SRR). The objectives of such a law deals with increasing in the knowledge of public actions aimed to improve the effectiveness of the SRR policy on school buildings. The actions of the CGIAM will consist in the identification of a significant number of school buildings in Italy, mainly in terms of type of construction and material, on which calibrate specific synthetic parameters and test models. Furthermore, the activities are addressed to quantitatively evaluation of intervention efficacy, to set up simple systems of instrumental monitoring, even able to test the possibility of periodical checks of the state of general preservation. The main issues carried on by the CGIAM mainly concern the completion and enrichment of the existing data base of school buildings, even through the collaboration of the Ministries and other relevant Italian research institutions, the evaluation of seismic hazard and site condition analysis as well as the definition of other seismic risk factors. Nevertheless a cost-benefit analysis as well as application and dissemination of such tools are proposed too. At the same time, the CGIAM contributes to the definition of experimental installation and use of a Simplified Accelerometric Monitoring Network for school buildings comprehensive of testing phase on a limited number of structures. The work proposes a synthetic overview of the employed methodologies as well as the first results arising from the research and implementation activities.

    2011-03-01

    The purpose of the present study was to determine the coping strategies of medical students and to investigate the effects of coping strategies on student satisfaction and academic achievement with different instruction methods. A total of 152 medical students was followed throughout the first 2 yr of medical education between 2008 and 2010. Students completed a sociodemographic questionnaire and revised form of the Ways of Coping questionnaire both at the beginning of the first year and at the end of the second year. These forms provided data about the characteristics and main coping strategies (problem focused or emotion focused) of the students and revealed the change over time. At the end of the second year, participants also completed a satisfaction questionnaire asking their satisfaction with lectures, problem-based learning, and practicals. The authors used block, problem-based learning, and practical exam scores of the students attained in the past 2 yr as academic achievement indicators. No sociodemographic variable was related to coping strategy. The majority of students (80.9%) adopted problem-focused coping. A shift occurred in the main coping strategies of some students in both sides. Problem-focused coping scores decreased over time. Problem-focused coping positively correlated with satisfaction with practicals and practical exam scores, whereas emotion-focused coping showed the same correlation negatively. The main coping strategy also predicted satisfaction and exam success in practicals. In conclusion, a main coping strategy may be helpful to predict student satisfaction and academic achievement with some student-centered instruction methods. Determining undesired coping strategies may provide an opportunity for intervention to prevent relevant dissatisfaction and failure.

    Full Text Available Young people in Muslim majority countries are a valuable asset and investing in them can bring tremendous social and economic benefits. They also face many challenges that undermine their ability to develop and contribute to society. To make the most of the opportunity, these countries must find ways to increase the human and social capital of their respective youth populations. Youth participation in formal and non-formal educational settings such as schools and community programs has been identified as an effective approach to enhancing young people’s experiences. Building on initial findings from Malaysia, the current paper puts forth the concept of youth-adult partnership (Y-AP as a strategy for schools. Y-AP has been shown to enhance personal agency, empowerment and connection to community, three attributes that are critical for Muslim youth to play more substantive roles in national development. The paper further attempts to frame Y-AP within an Islamic socio-historical lens, drawing on examples from the Prophet Muhammad SAW and the early Muslim community to show how developmental relationships were central to the social and educational culture within the Prophet’s community. Permalink/DOI: http://dx.doi.org/10.15408/sd.v2i2.2810

    Meritocratic ideology can promote system justification and the perpetuation of inequalities. The present research tests whether priming merit in the school context enhances the effect of socioeconomic status (SES) on school achievement. French fifth graders read a text priming either school merit or a neutral content, reported their French and mathematics self-efficacy as well as their belief in school meritocracy (BSM), and then took French and mathematics tests. Compared to the neutral condition, the merit prime condition increased the SES achievement gap. Self-efficacy and BSM were tested as two potential mediators of the effect. The results support a mediated moderation model in which belief in school meritocracy is the mechanism through which the merit prime increased the SES achievement gap. © 2017 The British Psychological Society.

    Full Text Available  Recent movements of citizen participation have found on the Internet and the Social Networks a favorable environment for development, which should lead us to a pedagogical reflection about the potential of virtual spaces for citizenship education. This article presents the theoretical basis and the pilot project of a school work which allows us to promote a concept of digital literacy that includes digital and civic competence. From the classic Antigone, conceived as the first act of civil disobedience, we explore the categories of public and private, which are perceived on this narration as opposite areas. Then we propose to understand the school as a space of conversation between both contexts. For this task, the project brings together the provocative capacity of classic literature and the potential of transmedia storytelling, where pupils are not only consumers but also critical participants before the social reality.y.

    Baptista, Geilsa Costa Santos; El-Hani, Charbel Niño

    2009-04-01

    This paper reports results obtained in pedagogical interventions in a Brazilian public high school which aimed at promoting a dialogue between scientific and traditional knowledge in the context of biology teaching. The interventions were based on the use of a didactic material and teaching sequence elaborated on the grounds of school knowledge about botany, as presented in biology textbooks, and interviews with students who were also farmers, so as to gather data about their ethnobiological knowledge. Our goal was to develop and test resources that can offer support for teachers who wish to build a dialogue between different ways of knowing in multicultural settings. Our results indicate that the use of the didactic material and teaching sequence indeed created possibilities for a dialogue between the students’ ethnobiological knowledge and biology school knowledge. We observed some shortcomings in classroom practice, partly reflecting our very choice of subject matter to develop the teaching sequence. But the interventions also revealed important limitations that we regard as representative of problems that may generally make multicultural science teaching a hard goal to achieve. It was clear that important shortcomings were related to teachers’ difficulties to conduct a dialogue between ways of knowing in a science classroom, and, thus, called attention to the importance of introducing a multicultural dimension into teacher education. We also observed that the fact that students did not show much sensitivity towards dealing with cultural diversity was a factor constraining the success of the interventions. These results highlight the importance of proposing and testing teacher education initiatives aiming at preparing them to teach science in a culturally sensitive manner, and also managing classroom tensions and conflicts so as to make it possible an effective dialogue between different ways of knowing in a multicultural setting.

  2. Ways of incorporating photographic images in learning and assessing high school biology: A study of visual perception and visual cognition

    Science.gov (United States)

    Nixon, Brenda Chaumont

    This study evaluated the cognitive benefits and costs of incorporating biology-textbook and student-generated photographic images into the learning and assessment processes within a 10th grade biology classroom. The study implemented Wandersee's (2000) 20-Q Model of Image-Based Biology Test-Item Design (20-Q Model) to explore the use of photographic images to assess students' understanding of complex biological processes. A thorough review of the students' textbook using ScaleMaster R with PC Interface was also conducted. The photographs, diagrams, and other representations found in the textbook were measured to determine the percentage of each graphic depicted in the book and comparisons were made to the text. The theoretical framework that guided the research included Human Constructivist tenets espoused by Mintzes, Wandersee and Novak (2000). Physiological and cognitive factors of images and image-based learning as described by Robin (1992), Solso (1997) and Wandersee (2000) were examined. Qualitative case study design presented by Yin (1994), Denzin and Lincoln (1994) was applied and data were collected through interviews, observations, student activities, student and school artifacts and Scale Master IIRTM measurements. The results of the study indicate that although 24% of the high school biology textbook is devoted to photographic images which contribute significantly to textbook cost, the teacher and students paid little attention to photographic images other than as aesthetic elements for creating biological ambiance, wasting valuable opportunities for learning. The analysis of the photographs corroborated findings published by the Association American Association for the Advancement of Science that indicated "While most of the books are lavishly illustrated, these representations are rarely helpful, because they are too abstract, needlessly complicated, or inadequately explained" (Roseman, 2000, p. 2). The findings also indicate that applying the 20-Q

    “最是书香能致远”。多读书、读好书是一个人提高素质的重要方法。良好的阅读使学生能够感悟对世间情感、态度、生活观的不同认识,理性的形成对社会、对生活的正确看法。书香校园中浓浓书香会浸润师生的思想品质和道德情操。而强大的“书香”气场能为“立德树人”提供成长正能量。要加强中小学学校读书建设就要师生同读,形成良好的阅读环境;家校共育,培养良好的阅读习惯;书香养德,共育优秀的社会公民。%"Books are the most elegant thing that can let people reach further". Reading more good books is one important way to improve a person's quality. Good reading can make students feel the different understanding of emotion, attitude and outlook on world, rationally form the right ideas about society and life. Elegant thick book fragrance will infiltrate the teachers and students' ideological quality and moral sentiment in scholarly campus. And powerful "elegant book aura" can provide positive energy for growth. To strengthen reading construction of primary and secondary school, both teachers and students should read to form a good reading environment, to develop good reading habits by home and school co-culture. Reading books can cultivate virtue and produce outstanding social citizenship.

    2016-01-01

    I report the result of a which-way experiment based on Young's double-slit experiment. It reveals which slit photons go through while retaining the (self) interference of all the photons collected. The idea is to image the slits using a lens with a narrow aperture and scan across the area where the interference fringes would be. The aperture is wide enough to separate the slits in the images, i.e., telling which way. The illumination pattern over the pupil is reconstructed from the series of slit intensities. The result matches the double-slit interference pattern well. As such, the photon's wave-like and particle-like behaviors are observed simultaneously in a straightforward and thus unambiguous way. The implication is far reaching. For one, it presses hard, at least philosophically, for a consolidated wave-and-particle description of quantum objects, because we can no longer dismiss such a challenge on the basis that the two behaviors do not manifest at the same time. A bold proposal is to forgo the concep...

  14. On the Way of Educational Reform: Thai High School Physics Teachers' Conceptions of the Student-Centered Approach and Their Perceptions of Their Classroom Practices

    Science.gov (United States)

    Chaumklang, Kawin

    During the past two decades, the student-centered approach has been widely promoted and accepted by the educational community as one of the most effective instructional approaches. It has been continually developed and revised to match our current understanding of how humans learn (American Psychological Association, 1997). It is based upon the belief that students should take responsibility for their own learning. Thus, curriculum, instruction, and assessment should be carefully designed to stimulate, facilitate, and accelerate students' learning as much as possible. In order to do so, the teacher needs to take the following factors into consideration: students' cognitive structures, metacognitive and regulative skills, motivation and affective states, developmental and individual differences, and social supports. However, the term student-centered has been defined and described by researchers and scholars in many different ways. Little is known about how practicing teachers conceptualize this term and how they perceive their classroom practices in relation to these conceptions. The purpose of this study was to utilize a qualitative multiple-case study approach to investigate teachers' conceptions of the student-centered approach and their perceptions of their classroom practices. Four Thai high school physics teachers, who were considered products of the current student-centered educational reform movement in Thailand, participated in this study. Data were collected for one learning unit (three to eight weeks) through classroom observations, semi-structured interviews, and document analysis. The data analysis revealed that teachers' conceptions of student-centered curriculum, instruction, and assessment had three common characteristics: (a) students' active participation; (b) special emphasis on students' background knowledge, understanding, motivation, affective states, and learning capability; and (c) benefits to students. The results also indicated that there

This is the premise behind the Organization Zoo series. Valve Corporation (Valve is an unusual firm. It is a rare example of a firm that appears to operate without any formal hierarchy in its organization. What can we learn about the viability of authority hierarchies from Valve’s way of organizing? We wrote a brief account of Valve based on public information sources and asked several renowned organizational experts to comment on this unusual firm. We asked them to write a short commentary on what the Valve example means for organizational theorists and practitioners. Thankfully, they all accepted, and we are excited to present the results of their thinking in this first “exhibit” in the Organization Zoo.

    Ruy Antônio Wanderley Rodrigues de Miranda

    2016-03-01

    Full Text Available Historically, physical education in Brazil has been coming through a long process for achieving its position in regular schools. Conquering this place is owed to a large set of debates about the most varied pedagogical concepts.  This study aims at analyzing the body feelings of a blind student and phenomenologically describing this student’s perceptions of school spaces when influenced by the use of tactile maps. The study adopted a qualitative approach from a theoretical-methodological perspective of the case study with phenomenological-existential inspiration.  Based on the dialogues in this study, the authors understood that tactile maps, mediated by the student’s body feelings, represented significant importance to boost memorization of school spaces. This allowed more reliable guidance and safer mobility to that blind student and his own challenges of overcoming physical and attitudinal barriers when he needed to move around daily at school and during physical education classes.

    Sangeet S Khemlani

    Full Text Available Many theorists argue that the probabilities of unique events, even real possibilities such as President Obama's re-election, are meaningless. As a consequence, psychologists have seldom investigated them. We propose a new theory (implemented in a computer program in which such estimates depend on an intuitive non-numerical system capable only of simple procedures, and a deliberative system that maps intuitions into numbers. The theory predicts that estimates of the probabilities of conjunctions should often tend to split the difference between the probabilities of the two conjuncts. We report two experiments showing that individuals commit such violations of the probability calculus, and corroborating other predictions of the theory, e.g., individuals err in the same way even when they make non-numerical verbal estimates, such as that an event is highly improbable.

Forty boys and girls took part and we selected over 400 photographs they had taken. The article draws attention to the importance of student ‘voices’ to show the interaction processes and the value of participatory photography as an approach that encourages their participation beyond the traditional interviews and field observations. The results acknowledge the value of photography to reflect the relationships among adolescents. However, while the experiment was positively rated by the participants, the study recognises the risks taken and the achievements, constraints, dilemmas and difficulties encountered by the investigators carrying out the research.

Adolescence is a unique phenomenon, varying according to culture, social class, race, gender and age, configuring distinctive ways of experiencing it. All this diversity, however, enables to develop relations with teenagers, including attention, nurturing, comfort, patience and sensitiveness, besides getting across curricular contents.

    Three undergraduate students, from Leiden University in the Netherlands, have discovered an extrasolar planet. The extraordinary find, which turned up during their research project, is about five times as massive as Jupiter. This is also the first planet discovered orbiting a fast-rotating hot star. Omega Centauri ESO PR Photo 45a/08 A planet around a hot star The students were testing a method of investigating the light fluctuations of thousands of stars in the OGLE database in an automated way. The brightness of one of the stars was found to decrease for two hours every 2.5 days by about one percent. Follow-up observations, taken with ESO's Very Large Telescope in Chile, confirmed that this phenomenon is caused by a planet passing in front of the star, blocking part of the starlight at regular intervals. According to Ignas Snellen, supervisor of the research project, the discovery was a complete surprise. "The project was actually meant to teach the students how to develop search algorithms. But they did so well that there was time to test their algorithm on a so far unexplored database. At some point they came into my office and showed me this light curve. I was completely taken aback!" The students, Meta de Hoon, Remco van der Burg, and Francis Vuijsje, are very enthusiastic. "It is exciting not just to find a planet, but to find one as unusual as this one; it turns out to be the first planet discovered around a fast rotating star, and it's also the hottest star found with a planet," says Meta. "The computer needed more than a thousand hours to do all the calculations," continues Remco. The planet is given the prosaic name OGLE2-TR-L9b. "But amongst ourselves we call it ReMeFra-1, after Remco, Meta, and myself," says Francis. The planet was discovered by looking at the brightness variations of about 15 700 stars, which had been observed by the OGLE survey once or twice per night for about four years between 1997 and 2000.

    CYP1B1, a recently described dioxin inducible oxidoreductase, is a member of the cytochrome P450 superfamily involved in the metabolism of estradiol, retinol, benzo[a]pyrene, tamoxifen, melatonin, sterols etc. It plays important roles in numerous physiological processes and is expressed at mRNA level in many tissues and anatomical compartments. CYP1B1 has been implicated in scores of disorders. Analyses of the recent studies suggest that CYP1B1 can serve as a universal/ideal cancer marker and a candidate gene for predictive diagnosis. There is plethora of literature available about certain aspects of CYP1B1 that have not been interpreted, discussed and philosophized upon. The present analysis examines CYP1B1 as a peculiar gene with certain distinctive characteristics like the uniqueness in its chromosomal location, gene structure and organization, involvement in developmentally important disorders, tissue specific, not only expression, but splicing, potential as a universal cancer marker due to its involvement in key aspects of cellular metabolism, use in diagnosis and predictive diagnosis of various diseases and the importance and function of CYP1B1 mRNA in addition to the regular translation. Also CYP1B1 is very difficult to express in heterologous expression systems, thereby, halting its functional studies. Here we review and analyze these exceptional and startling characteristics of CYP1B1 with inputs from our own experiences in order to get a better insight into its molecular biology in health and disease. This may help to further understand the etiopathomechanistic aspects of CYP1B1 mediated diseases paving way for better research strategies and improved clinical management.

    The InSIGHT mission to Mars (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) supported by NASA, IPGP and CNES, is a great opportunity for teachers and pupils to study the Red planet, but also to study other fields of geology at school, such as seismology. With our pupils, we are following the InSight mission and we look forward to analyze seismic data registered by the SEIS seismometer , once it will be available (the InSight mission will launch in 2018 from California, and will land to Mars in 2018 or 2019). As this mission needs meteorite impacts to generate seismic waves ( to discover the Martian interior structure) , we've decided to model those meteorite strikes in the classroom. With our pupils, we've modeled meteorite impact craters with different impactors , such as tennis balls, baseballs, or pingpong balls, and used an analogue substratum made by flour and cocoa. Then, we kept on going our geophysical investigation , studying several parameters. For instance, we've studied the link between size of impactor and size of crater , the link between mass of impactor and Crater Formation, and the link between velocity of impactor and crater formation. In this geophysical approach , potential energy and kinetic energy can be introduced in terms of energy transfer as the impactor falls ( calculation of the velocity of impact and plotting that against crater diameter using v = (2gh)1/2). For each crater formation made in class by students, we have registered seismological data thanks to Audacity software, and study the seismic signal propagation. This exemple of hands-on activity with pupils, and its wide range of geophysical calculation shows how we can do simple experiment modeling meteorite crater impact and exploit registered seismological data at school. We've finaly focused our work with the very famous example of the astroblema of Rochechouart in the South-west of France ( crater formation : - 214 My) , in which it's easy to

In particular, it has turned out that not all black-hole-equilibrium configurations are characterized by their mass, angular momentum and global charges. Moreover, the high degree of symmetry displayed by vacuum and electro vacuum black-hole spacetimes ceases to exist in self-gravitating non-linear field theories. This text aims to review some developments in the subject and to discuss them in light of the uniqueness theorem for the Einstein-Maxwell system.

  17. Fingerprinting the Milky Way

    2007-03-01

    Using ESO's Very Large Telescope, an international team of astronomers has shown how to use the chemical composition of stars in clusters to shed light on the formation of our Milky Way. This discovery is a fundamental test for the development of a new chemical tagging technique uncovering the birth and growth of our Galactic cradle. The formation and evolution of galaxies, and in particular of the Milky Way - the 'island universe' in which we live, is one of the major puzzles of astrophysics: indeed, a detailed physical scenario is still missing and its understanding requires the joint effort of observations, theories and complex numerical simulations. ESO astronomer Gayandhi De Silva and her colleagues used the Ultraviolet and Visual Echelle Spectrograph (UVES) on ESO's VLT to find new ways to address this fundamental riddle. ESO PR Photo 15/07 ESO PR Photo 15/07 The Cluster Collinder 261 "We have analysed in great detail the chemical composition of stars in three star-clusters and shown that each cluster presents a high level of homogeneity and a very distinctive chemical signature," says De Silva, who started this research while working at the Mount Stromlo Observatory, Australia. "This paves the way to chemically tagging stars in our Galaxy to common formation sites and thus unravelling the history of the Milky Way," she adds. "Galactic star clusters are witnesses of the formation history of the Galactic disc," says Kenneth Freeman, also from Mount Stromlo and another member of the team. "The analysis of their composition is like studying ancient fossils. We are chasing pieces of galactic DNA!" Open star clusters are among the most important tools for the study of stellar and galactic evolution. They are composed of a few tens up to a few thousands of stars that are gravitationally bound, and they span a wide range of ages. The youngest date from a few million years ago, while the oldest (and more rare) can have ages up to ten billion years. The well

    Full Text Available Abstract Background There is limited knowledge as to whether obesity prevention interventions are able to produce change in the determinants hypothesized to precede change in energy balance-related behaviors in young people. The aim of this study was to evaluate the effect of a multi-component intervention on a wide range of theoretically informed determinants of physical activity (PA and sedentary behavior (SB. Moderation effects of gender, weight status and parental education level and whether the perceived intervention dose received influenced the effects were also explored. Methods The HEIA study was a 20-month school-based, randomized controlled trial to promote healthy weight development. In total, 1418 11-year-olds participated at baseline and post-intervention assessment. Enjoyment, self-efficacy, perceived social support from parents, teachers and friends related to PA, perceived parental regulation of TV-viewing and computer/game-use and perceived social inclusion at schools were examined by covariance analyses to assess overall effects and moderation by gender, weight status and parental education, mid-way and post-intervention. Covariance analyses were also used to examine the role of intervention dose received on change in the determinants. Results At mid-way enjoyment (p = .03, perceived social support from teachers (p = .003 and self-efficacy (p = .05 were higher in the intervention group. Weight status moderated the effect on self-efficacy, with a positive effect observed among the normal weight only. At post-intervention results were sustained for social support from teachers (p = .001, while a negative effect was found for self-efficacy (p = .02. Weight status moderated the effect on enjoyment, with reduced enjoyment observed among the overweight. Moderation effects for parental education level were detected for perceived social support from parents and teachers. Finally, positive effects on several

  2. The Lasso Problem and Uniqueness

    CERN Document Server

    Tibshirani, Ryan J

    2012-01-01

    The lasso is a popular tool for sparse linear regression, especially for problems in which the number of variables p exceeds the number of observations n. But when p>n, the lasso criterion is not strictly convex, and hence it may not have a unique minimum. An important question is: when is the lasso solution well-defined (unique)? We review results from the literature, which show that if the predictor variables are drawn from a continuous probability distribution, then there is a unique lasso solution with probability one, regardless of the sizes of n and p. We also show that this result extends easily to $\\ell_1$ penalized minimization problems over a wide range of loss functions. A second important question is: how can we deal with the case of non-uniqueness in lasso solutions? In light of the aforementioned result, this case really only arises when some of the predictor variables are discrete, or when some post-processing has been performed on continuous predictor measurements. Though we certainly cannot c...

    Optometric education has been faced with ever-increasing expectations. These include the ability to educate students and practitioners to care for new patient populations, deal with more diverse and complex clinical problems, to be significant participants in the research community and to fulfill leadership positions within the profession. To fulfill this expectation, schools and colleges need to diversify their program offerings to attract and educate unique student populations who come from diverse backgrounds and bring a range of pre-existing knowledge and skills. This paper provides an overview of The New England College of Optometry's efforts in this area and two programs, the "Advanced Standing International Program" and the "Accelerated Doctor of Optometry Degree Program," are examined in detail. An emphasis is placed on outcomes assessment to ensure the programs are fulfilling their purpose and the results of a retrospective analysis of the two programs is provided.

  6. Uniqueness theorems in linear elasticity

    CERN Document Server

    Knops, Robin John

    1971-01-01

    The classical result for uniqueness in elasticity theory is due to Kirchhoff. It states that the standard mixed boundary value problem for a homogeneous isotropic linear elastic material in equilibrium and occupying a bounded three-dimensional region of space possesses at most one solution in the classical sense, provided the Lame and shear moduli, A and J1 respectively, obey the inequalities (3 A + 2 J1) > 0 and J1>O. In linear elastodynamics the analogous result, due to Neumann, is that the initial-mixed boundary value problem possesses at most one solution provided the elastic moduli satisfy the same set of inequalities as in Kirchhoffs theorem. Most standard textbooks on the linear theory of elasticity mention only these two classical criteria for uniqueness and neglect altogether the abundant literature which has appeared since the original publications of Kirchhoff. To remedy this deficiency it seems appropriate to attempt a coherent description ofthe various contributions made to the study of uniquenes...

    We examine numerically a sequence of free data for the conformal thin sandwich (CTS) equations representing non-linearly perturbed Minkowski spacetimes. We find only one solution for the standard (four) CTS equations; however, we find {\\em two} distinct solutions for the same free data when the lapse is determined by a fifth elliptic equation arising from specification of the time derivative of the mean curvature. For a given {\\em physical} (conformally scaled) amplitude of the perturbation, the solution for the physical data $g_{ij}, K_{ij}$ nevertheless appears to be unique.

    2006-01-01

    We study the appearance of multiple solutions to certain decompositions of Einstein's constraint equations. Pfeiffer and York recently reported the existence of two branches of solutions for identical background data in the extended conformal thin-sandwich decomposition. We show that the Hamiltonian constraint alone, when expressed in a certain way, admits two branches of solutions with properties very similar to those found by Pfeiffer and York. We construct these two branches analytically for a constant-density star in spherical symmetry, but argue that this behavior is more general. In the case of the Hamiltonian constraint this non-uniqueness is well known to be related to the sign of one particular term, and we argue that the extended conformal thin-sandwich equations contain a similar term that causes the breakdown of uniqueness.

    In this session, we discuss different approaches to reaching large audiences. In addition to star parties and astronomy events, the audiences for some of the events include music concerts or festivals, sick children and their families, minority communities, American Indian reservations, and tourist sites such as the National Mall. The goal is to bring science directly to the public—to people who attend astronomy events and to people who do not come to star parties, science museums, or science festivals. These programs allow the entire community to participate in astronomy activities to enhance the public appreciation of science. These programs attract large enthusiastic crowds often with young children participating in these family learning experiences. The public will become more informed, educated, and inspired about astronomy and will also be provided with information that will allow them to continue to learn after this outreach activity. Large and unique audiences often have common problems, and their solutions and the lessons learned will be presented. Interaction with the participants in this session will provide important community feedback used to improve astronomy outreach for large and unique audiences. New ways to expand astronomy outreach to new large audiences will be discussed.

  10. Realities of teaching in a multiethnic school

    1991-03-01

    New attitudes in education systems to minority languages and cultures are evident in many places. This welcome change in social values presents problems of a new kind for the management of modern schools. This article begins by arguing that the starting point for solving these problems is an understanding of the realities of the cultural community immediately beyond the school's boundaries. It continues by examining two component variables affecting the school's multiethnic reality: the attitudes and professional knowledge that teachers possess relevant to the languages and cultures of the school; and the linguistic and cultural diversity of the children themselves. It recommends that the one comprehensive method for coping with the many unique problems that these factors can introduce into a school is for the staff to develop coherent policies that deliberately set out to solve the multiethnic school's problems. A later section discusses the two major approaches to providing language instruction for children in multiethnic schools: bilingual schooling, which is of special value when there are many culturally different children in large single language/culture groups; and school organisation for second language teaching, which is a partial solution in providing for a diversity of culturally different children in smaller numbers. Discussion covers practices that are already operating successfully in pluralist schools in many places. To suggest how it might be possible to modify and build on the foundations of contemporary schooling to make the school more organic to its cultural community, the article reports a case study of one contemporary innercity school which has made major organisational and curricular changes with considerable success. The article concludes that great advantages can come from well-run multiethnic schools, not just for the institution of education itself. It also suggests that multiethnic schools controlled and run by remote bureaucracies and

    Full Text Available Abstract Background Inconsistent effects of school-based obesity prevention interventions may be related to how different subgroups receive them. The aim of this study was to evaluate the effect of an intervention program, including fact sheets to parents and classroom components, on intake of sugar-sweetened beverages (SSB and screen time. Further, to explore whether potential effects and parental involvement varied by adolescents' gender, weight status (WS and parental educational level. Methods In total, 1465 11-year-olds participated at the pre-test and the 8 month mid-way assessment of the HEIA study. Parents (n = 349 contributed with process evaluation data. Self-reported intake of SSB was collected from the 11-year-olds assessing frequency and amount, while time used on watching TV/DVD and computer/game-use (weekday and weekend day were assed by frequency measures. Data on awareness of the intervention and dose received were collected from parents. Covariance analyses (ANCOVA were conducted testing for effects by gender and for moderation by WS and parental education. Results Time spent on TV/DVD (week p = 0.001, weekend p = 0.03 and computer/game-use (week p = 0.004, weekend p Conclusions The preventive initiatives appeared to change behaviour in girls only. This study suggests that exploration of potential beneficial or negative effects of intervention in subgroups is important. In formative evaluation of obesity prevention studies it seems warranted to include issues related to gender, WS and parental involvement in order to enhance the effectiveness of preventive initiatives.

Through data analysis, the main result is as follows:①Test anxiety has negative correlation with the attribution about success or failure.②The one with high-text anxiety is easy to attribute success to the facts which is external and instability and attribute failure to the facts which is internal and stability. The one with low-text anxiety is opposite with it.

  13. The Fourth Way in Finland

    2008-01-01

    Full Text Available This article focuses on the general history of the Fourth Way in Finland. The Fourth Way, or simply ‘the Work’, began as a Greco-Armenian man named Georges Ivanovich Gurdjieff (1866?–1949 gathered groups of pupils in St Petersburg and Moscow in 1912. To these groups, Gurdjieff started to teach what he had learned and synthesized between ca 1896 and 1912 during his travels on spiritual search of Egypt, Crete, Sumeria, Assyria, the Holy Land, Mecca, Ethiopia, Sudan, India, Afghanistan, the northern valleys of Siberia, and Tibet. Neither Gurdjieff nor any of his disciples called themselves a church, a sect, or anything alike, but referred to themselves simply as ‘the Work’, or as ‘the Fourth Way’. The name ‘the Fourth Way’ originates in a Gurdjieffian view that there are essentially three traditional ways of spiritual work: those of a monk, a fakir, and a yogi. These ways do not literally refer to the activities of a monk, a fakir, and a yogi, but to similar types of spiritual work emphasizing exercise of emotion, body, or mind. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West.

    Di Salvo, Donald N; Park, Joseph; Laing, Faye C

    2012-04-01

    This case series describes a unique sonographic appearance consisting of numerous microcysts and punctate echogenic foci seen on renal sonograms of 10 adult patients receiving chronic lithium therapy. Clinically, chronic renal insufficiency was present in 6 and nephrogenic diabetes insipidus in 2. Sonography showed numerous microcysts and punctate echogenic foci. Computed tomography in 5 patients confirmed microcysts and microcalcifications, which were fewer in number than on sonography. Magnetic resonance imaging in 2 patients confirmed microcysts in each case. Renal biopsy in 1 patient showed chronic interstitial nephritis, microcysts, and tubular dilatation. The diagnosis of lithium nephropathy should be considered when sonography shows these findings.

    2014-12-01

    Mucormycosis remains a devastating invasive fungal infection, with high mortality rates even after active management. The disease is being reported at an alarming frequency over the past decades from India. Indian mucormycosis has certain unique features. Rhino-orbito-cerebral presentation associated with uncontrolled diabetes is the predominant characteristic. Isolated renal mucormycosis has emerged as a new clinical entity. Apophysomyces elegans and Rhizopus homothallicus are emerging species in this region and uncommon agents such as Mucor irregularis and Thamnostylum lucknowense are also being reported. This review focuses on these distinct features of mucormycosis observed in India.

    1995-01-01

    An oral drug delivery system using proteinoid microspheres is discussed with respect to its unique dependence on pH. It has been found that certain drugs such as insulin and heparin can be encapsulated in proteinoid spheres at stomach pH's (1-3). These spheres also dissemble at intestinal pH's (6-7) releasing the drug for absorption. Using this technique low molecular weight heparin and human growth hormone have been orally delivered successfully to several animal species. Future work has been proposed to study the interaction and binding of the specific drugs with synthesized oligopeptides.

  10. Unique features of space reactors

    Science.gov (United States)

    Buden, David

    Space reactors are designed to meet a unique set of requirements; they must be sufficiently compact to be launched in a rocket to their operational location, operate for many years without maintenance and servicing, operate in extreme environments, and reject heat by radiation to space. To meet these restrictions, operating temperatures are much greater than in terrestrial power plants, and the reactors tend to have a fast neutron spectrum. Currently, a new generation of space reactor power plants is being developed. The major effort is in the SP-100 program, where the power plant is being designed for seven years of full power, and no maintenance operation at a reactor outlet operating temperature of 1350 K.

  11. The Evolution of Human Uniqueness.

    The human species is an outlier in the natural world. Two million years ago our ancestors were a slightly odd apes. Now we occupy the largest ecological and geographical range of any species, have larger biomass, and process more energy. Usually, this transformation is explained in terms of cognitive ability-people are just smarter than all the rest. In this paper I argue that culture, our ability to learn from each other, and cooperation, our ability to make common cause with large groups of unrelated individuals are the real roots of human uniqueness, and sketch an evolutionary account of how these crucial abilities co-evolved with each other and with other features of our life histories.

    measured (by obtaining spectra of the arcs and measuring their redshift). The masses of galaxy clusters are important for the determination, for instance of the mean density and distribution of matter in the universe. This is because these clusters are the most massive, clearly defined objects known and as such trace these parameters in the universe on very large scales. Another possibility to derive the cluster mass is offered by X-ray observations, because the distribution of the hot, X-ray emitting gas traces the gravitational field of the cluster. Recently, in some clusters there has been a discrepancy between the mass determined in this way and that found from gravitational lensing effects. The team of astronomers now hopes that follow-up X-ray observations of RXJ1347.5-1145 will help to solve this puzzle. Moreover, the combination of extremely high X-ray brightness and the possibility to perform a rather accurate mass determination by the gravitational lensing effect makes this particular cluster a truly unique object. In view of the exceptional X-ray brightness, a very high mass is expected. The exact determination will be possible, as soon as spectra have been obtained of the two arcs. Contrary to what is the case in other clusters, this will not be so difficult, due to their unusual brightness and their ideal geometrical configuration.

    2014-01-01

    Tibetan medicine is known as the knowledge of healing in the Four Tantras, the main medical text studied by Tibetan doctors. In the 8th century, King Trisong Deutsen (718-785 CE) invited eminent physicians from India, China, Persia, East Turkestan, Mongolia, and Nepal for the First International Medical Symposium in Samye, Tibet and ordered his personal physician Elder Yuthog Yonten Gonpo (708-833 CE), who lived 125 years, and participated in this conference to summarize. By combining all the information available and presented during this symposium, he compiled the Four Tantras. He established the Tanadug medical school at Menlung in Kongpo, Southern Tibet in 763 CE, and worked for the propagation of Tibetan medicine. He is considered an emanation of Medicine Buddha, who is a symbol of mental and physical well being. In his left hand, the Medicine Buddha clasps a begging bowl with long-life nectar, signifying immortality, and in his right, the Chebulic myrobalan (Haritaki), a symbol of good health. Chebulic myrobalan, Belleric myrobalan, and Emblic myrobalan are together called the "3 Fruits" and are common ingredients in Tibetan medicines. Prof. Omura, Y of NY Medical College evaluated these "3 Fruits" and found that one of them available as a "Haritaki," had the highest normal cell telomere increasing effect by optimal dose, with improvement of circulation all over the body, which in turn inhibits cancer activity. He considered Tibetan medicine to be the most advanced medicine in the world before the 19th Century with its well-organized systematic method as described by colorful Tibetan medical paintings by Sangye Gyamtso (1653-1705 CE). During a typical diagnosis, the physician examines the patients' tongue, radial arteries for pulse beats by the index, middle, and ring fingers of both hands and the urine for features like color, vapor, and bubbles, etc.

    We describe an experiment to measure the mass of the Milky Way galaxy. The experiment is based on calculated light travel times along orthogonal directions in the Schwarzschild metric of the Galactic center. We show that the difference is proportional to the Galactic mass. We apply the result to light travel times in a 10cm Michelson type interferometer located on Earth. The mass of the Galactic center is shown to contribute 10^-6 to the flat space component of the metric. An experiment is proposed to measure the effect.

    Culture, in a wide sense, is the sum total of material and spiritual products created by man in the historical process of a socialpractice. In a narrow sense, it refers to a social ideology and the political system and constitutional organization corresponding to the ideology.Language has a very special position in this big culture and it cannot be well taught and learnt without the introducing of cultural knowledge. One ofthe effective ways to increase awareness of the euhural is to learn the patterns of western everyday life.

    2012-01-01

    We investigate the physical properties of the progenitors of today living Milky Way-like galaxies that are visible as Damped Lya Absorption systems and Lya Emitters at higher redshifts (z ~ 2.3,5.7). To this aim we use a statistical merger-tree approach that follows the formation of the Galaxy and its dwarf satellites in a cosmological context, tracing the chemical evolution and stellar population history of the progenitor halos. The model accounts for the properties of the most metal-poor stars and local dwarf galaxies, providing insights on the early cosmic star-formation. Fruitful links between Galactic Archaeology and more distant galaxies are presented.

  8. Some unique superconductive Properties of Cuprates

    Science.gov (United States)

    Müller, K. A.

    2013-04-01

    Copper oxides are the only materials that show transition temperatures, Tc, above the boiling point of liquid nitrogen, with a maximum Tmc of 162 K under pressure. Their structure is layered, with one to several CuO2 planes, and upon hole doping, their transition temperature follows a dome-shaped curve with a maximum at Tmc. In the underdoped regime, i.e., below Tmc, a pseudogap T* is found, with T* always being larger than Tc, a property unique to the copper oxides [1]. In the superconducting state, Cooper pairs (two holes with antiparallel spins) are formed that exhibit coherence lengths on the order of a lattice distance in the CuO2 plane and one order of magnitude less perpendicular to it. Their macroscopic wave function is parallel to the CuO2 plane near 100% d at their surface, but only 75% d and 25 % s in the bulk, and near 100% s perpendicular to the plane in YBCO. There are two gaps with the same Tc [2]. As function of doping, the oxygen isotope effect is novel and can be quantitatively accounted for by a two-band vibronic theory [3] near Tmc, and underdoped below it till Tc = 0 with by a formula valid for (bi)polarons [4]. These cuprates are intrinsically heterogeneous in a dynamic way. In terms of quasiparticles, Jahn-Teller bipolarons are present at low doping, and aggregate upon cooling [1], so that probably ramified clusters and/or stripes are formed, leading over to a more Fermi-liquid-type behavior at large carrier concentrations above Tmc.

    Full Text Available The Mediterranean area have a special concept of competitiveness topic. Normally is that region not so industrial and knowledge based oriented as a North Europe.That countries can't reach the same development level as the north one. Lisbon's and Goethenburg's strategies create the main framework of development programme. Mediterranean programme is such a case. European internal market has forced the EU countries to increase competitiveness. The economic prosperity of countries is associated with their ability to generate or attract economic activities which are able to increase income by performing well on themarket. Financial crisis in the EU has changed the look on the competitiveness research. Economy in the main countries has to find way of recovery. Former giants of the financial world have found themselves suddenly facing bankruptcy.Inevitably, the crisis is also having an effect on households and businesses - economic growth has slowed sharply and in some EU countries unemployment has begun to increase for the first time in several years. Form that perspective we have to find the right solution of European competitiveness.

    2014-05-01

    The talk describes the main hallmarks in my nearly half a century activity in the field of archaeomagnetism. Beginning from zero in my country in 1967, now the Bulgarian database is the longest data set comprising the three geomagnetic characteristics. I consider that the determination of the direction and absolute palaeointensity from one and the same material is the most valuable input data for the important geomagnetic field modeling. The recovered full geomagnetic vector gives much more opportunities for different geophysical applications. The maintenance, filling up and revision of the local database remained my principle obligation during my professional way. As a result taking the advantage of our country to have plenty of prehistoric single and multilevel sites the knowledge of the geomagnetic field behavior was prolonged deeply in the past going to 6000 yrs BC. The usage of 14C dates will be discussed describing possible difficulties which can be encountered. The specific multilevel prehistoric sites, found mostly in the Near East and the Balkans, with clear stratigraphy are particularly useful for archaeomagnetic discovery of the past geomagnetic field behavior. In this respect the well-timed activity of geophysical teams following the archaeological excavations is very important for the future elucidation of geomagnetic secular variations. The constant tight contact with the archaeological community of each country during this process is crucial. Examples of most valuable topics of interest for archaeologists will be given in the talk as synchronizations, magnetic characteristics related to the type of ceramics, archaeomagnetic dating etc. This is an important task because we should keep their interest towards our studies giving us the necessary materials. Some obtained questionable results will be discussed parallel with the progress in understanding the physical processes in baked clay and its magnetic mineralogy. Going deeply in diagnosis of the

    contraction in that gas, many heavier elements were built up by nuclear processes in their interiors. As time passed, many of the stars of this and following stellar generations returned the processed matter to their surroundings at the ends of their lives, either during violent supernova explosions or via strong "stellar winds". In this way, the interstellar gas in the Milky Way system has ever since been continuously enriched with heavier elements. Stars of later generations like our Sun now contain those elements produced by their ancestors and we are indeed ourselves made up of them. Consequently, the early (and hence, old) stars in the Milky Way mainly differ from younger stars by containing very small amounts of such elements . Hunting the earliest stars Have some of those earliest stars survived to our days? In theory, at least, it would be possible that some of the lighter ones - having the longest lifetimes - are still around. But if so, where are they? During the past three decades, astronomers have desperately tried to find bona-fide representatives of the very first stellar generation(s) in the Milky Way, i.e. stars with no or, at most, extremely low abundance of elements other than hydrogen and helium. The researchers usually refer to such objects as Population III stars , the other two populations being stars with heavy-element abundances like the Sun (Population I) or somewhat less (Population II) [3]. The Hamburg/ESO survey Now, a group of astronomers from Germany, Sweden, Australia, Brazil and the USA [2] has found a giant star that has a concentration of heavy elements 200,000 times lower than the Sun, or about 20 times less than the previous "record" for this kind of star. It thus provides the researchers with a unique window towards the early stages of the formation of the Milky Way and a fine opportunity to study stellar gas with a composition close to that produced during the Big Bang. This is one important outcome of a systematic search for the most

    School violence has evolved into an identifiably pervasive public health problem. Adverse consequences of school violence vary from bullying to death. In 2007, 457,700 youth (ages 12-18) were victims of serious crimes with 34% occurring on school grounds or on the way to school. A concept analysis of school violence can expand and enhance awareness of the pervasive phenomenon of school violence. Rodgers and Knafl (1993) evolutionary concept analysis method was used to provide a guiding framework for examination of school violence. Related manuscripts from the extant interdisciplinary school violence literature were obtained from relevant health science databases, the Education Resources Information Center, and various governmental and specialty websites within the contemporary time frame of 2000-2010. Analysis revealed the enormous scope and complexity of the problem of school violence including bullying, physical fighting, weapon carrying, alcohol/substance use and street gang presence on school property, school-associated violent death, safe schools legislation, and violence prevention strategies. Forensic nurses across practice settings are uniquely positioned to intervene to improve health of these youth through identification, assessment, treatment, and referral. © 2012 International Association of Forensic Nurses.

    Unique mode of perception, or the ability to see things differently from others, is one of the psychological resources required for creative mental activities. Behavioral studies using ambiguous visual stimuli have successfully induced diverse responses from subjects, and the unique responses defined in this paradigm were observed in higher frequency in the artistic population as compared to the nonartistic population. However, the neural substrates that underlie such unique perception have yet to be investigated. In the present study, ten ambiguous figures were used as stimuli. The subjects were instructed to say what the figures looked like during functional MRI scanning. The responses were classified as "frequent", "infrequent" or "unique" responses based on the appearance frequency of the same response in an independent age- and gender-matched control group. An event-related analysis contrasting unique vs. frequent responses revealed the greatest activation in the right temporal pole, which survived a whole brain multiple comparison. An alternative parametric modulation analysis was also performed to show that potentially confounding perceptual effects deriving from differences in visual stimuli make no significant contribution to this temporopolar activation. Previous neuroimaging and neuropsychological studies have shown the involvement of the temporal pole in perception-emotion linkage. Thus, our results suggest that unique perception is produced by the integration of perceptual and emotional processes, and this integration might underlie essential parts of creative mental activities.

    This study tested the unique and joint effects of three significant relationships in young children's social lives, namely their relationships with mother, teacher, and peers, on three dimensions of self-concept (general, academic, and social). A sample of 113 children participated. Mother-child attachment quality was observed in preschool. In first grade, teacher ratings of teacher-child relationship quality, peer ratings of peer acceptance, and child reports of self-concept were administered. The results revealed domain-specific links between social relationships and self-concept dimensions. Specifically, academic self-concept related to teacher-child relationship quality, social self-concept to peer acceptance, and general self-concept to the quality of attachment to mother. Moreover, an indirect effect was revealed of earlier mother-child attachment quality on the academic dimension of self through its effect on current adult-child relationships in school. This way, the study uncovered the pathways through which significant social relationships shape the formation of young children's self-concept.

    2015-12-01

    On average, French children spend 18.5 years n schools. Improving the effectiveness of interventions in school setting aiming at promoting children's health and reducing health inequities is critical in public health. Evidence shows that a whole school approach, where there is coherence between the school's policies and practices that promote social inclusion and commitment to education, actually facilitates improved learning outcomes, increases emotional wellbeing and reduces health risk behaviours. Many factors govern the ways in which school health education is implemented and within these factors, staff commitment and partnership with local health professionals play a crucial role. The effectiveness of health promotion in schools is directly linked to the way in which school environment is supportive. There is a need to improve school organisation, ethos and environment as well as to invest in partnerships with local organisations and services especially the health professionals who are in charge of children's health.

  1. Amygdalar enlargement associated with unique perception.

    Asari, Tomoki; Konishi, Seiki; Jimura, Koji; Chikazoe, Junichi; Nakamura, Noriko; Miyashita, Yasushi

    2010-01-01

    Interference by amygdalar activity in perceptual processes has been reported in many previous studies. Consistent with these reports, previous clinical studies have shown amygdalar volume change in multiple types of psychotic disease presenting with unusual perception. However, the relationship between variation in amygdalar volume in the normal population and the tendency toward unusual or unique perception has never been investigated. To address this issue, we defined an index to represent the tendency toward unique perception using ambiguous stimuli: subjects were instructed to state what the figures looked like to them, and "unique responses" were defined depending on the appearance frequency of the same responses in an age- and gender-matched control group. The index was defined as the ratio of unique responses to total responses per subject. We obtained structural brain images and values of the index from sixty-eight normal subjects. Voxel-based morphometry analyses revealed a positive correlation between amygdalar volume and the index. Since previous reports have indicated that unique responses were observed at higher frequency in the artistic population than in the nonartistic normal population, this positive correlation suggests that amygdalar enlargement in the normal population might be related to creative mental activity.

  5. Applications for unique identifiers in the geological sciences

    Even though geology has always been a generalist discipline in many parts, approaches towards questions about Earth's past have become increasingly interdisciplinary. At the same time, a wealth of samples has been collected, the resulting data have been stored in in disciplinary databases, the interpretations published in scientific literature. In the past these resources have existed alongside each other, semantically linked only by the knowledge of the researcher and his peers. One of the main drivers towards the inception of the world wide web was the ability to link scientific sources over the internet. The Uniform Resource Locator (URL) used to locate resources on the web soon turned out to be ephemeral in nature. A more reliable way of addressing objects was needed, a way of persistent identification to make digital objects, or digital representations of objects, part of the record of science. With their high degree of centralisation the scientific publishing houses were quick to implement and adopt a system for unique and persistent identification, the Digital Object Identifier (DOI) ®. At the same time other identifier systems exist alongside DOI, e.g. URN, ARK, handle ®, and others. There many uses for persistent identification in science, other than the identification of journal articles. DOI are already used for the identification of data, thus making data citable. There are several initiatives to assign identifiers to authors and institutions to allow unique identification. A recent development is the application of persistent identifiers for geological samples. As most data in the geosciences are derived from samples, it is crucial to be able to uniquely identify the samples from which a set of data were derived. Incomplete documentation of samples in publications, use of ambiguous sample names are major obstacles for synthesis studies and re-use of data. Access to samples for re-analysis and re-appraisal is limited due to the lack of a central

    世界卫生组织指出:“健康不仅是没有疾病或者衰弱,而是身体、心理和社会适应处于完好的状态。”我国在2011年新颁布的《体育与健康课程标准》中也明确提出了社会适应目标。由此可见,社会适应对个体健康及发展的重要性。那么,对正处于生长发育关键时期的青少年学生培养社会适应性教学目标,更是具有现实性和时代性,为实现这一学习领域的水平目标,提高学生社会适应能力,学校体育教学将利用体育与健康课程、课外体育活动、课余体育竞赛、课余体育训练培养学生的自信心、人际交往能力、竞争意识和挫折承受能力,为适应未来的学习、工作和生活打下良好的基础。%World Health Organization has pointed out that:"health is not only the state without weakness or disease,but also the good condition that body and psychology are with social adaptation.The newly promulgated‘Curriculum Standards of Sports and Health’in 2011 also clearly put forward the goal of social adaptation.Thus, the importance of social adaptation to individual health and development can be revealed.Therefore,for those teenagers in their critical period of growing up,cultivating the teaching goal of social adaptation has more significance with reality and the times.In order to realize the goal of this study field and improve students’social adaptation ability,school physical education will take advantage of sports and health courses,extracurricular sports activities,extracurricular sports competitions and extracurricular sports training to develop students’ confidence,interpersonal skills,competitive consciousness and frustration tolerance to lay a good foundation for adapting to future learning,work and life.

  9. Political Explanation on Music by Confucian School from "The Way of Music Connects Politics"%由“声音之道,与政通矣”看儒家对音乐的政治化诠释

    2012-01-01

    Specialized in discussing on music education,the Book of Music is an important constituent part of the Confucian classical work,the Book of Rites.By the Book of Music,the Confucian school explains the influence of music to individuals and to society,and explains the idea of educating people to carry on political reforms by music.But the political function and the educating effect of music proper have been inappropriately exaggerated in their explanations to the effect of misleading the evolution of political thinking in feudal society,and of fairly negative influence to the development of music proper.Only by correct cognition of the essential property of music,and by clearing up the relations between music and its influence to morality and social politics,can the cognition be made on how to enable music develop correctly,and on how the state politics should be rationally carried out in balance.%《乐记》是儒家重要经典著作《礼记》中专门论述乐教的重要部分,儒家通过《乐记》诠释了音乐对个人对社会的影响,阐述了儒家通过音乐教化世人改良政治的理念。但音乐本身的政治功能和教化效果在儒家的诠释中被不恰当地夸大了,不仅误导了封建社会政治思想的演化,而且对音乐本身的发展造成了比较消极的影响。只有正确认识音乐的本质属性,将音乐与人性道德社会政治的影响关系厘清主次轻重,才能认识到音乐应当如何正确合理地发展,才能认识到国家政治应当如何理性平衡地运作。

    终身体育是目前最为先进的一种体育教育理念,在国家大力推行素质教育和全民健身计划的今天,为越来越多的人所重视。高校体育在终身体育系统(包括学前体育、学校体育和社会体育)中占有无与伦比的地位,它是学校体育和社会体育的衔接点,起着承前启后的“桥梁”作用。而高校体育作为我国学校体育(包括小学体育、中学体育和大学体育)的一个重要组成部分,是学校体育的最末阶段和学生体育的最高层次,也是培养大学生终身体育意识最为关键的时期。高校体育教学理应抓住此关键时期,努力探寻培养学生终身体育意识之途径,如加强对体育的理性认识,培养大学生的体育意识;采用灵活多样教学方法,培养大学生的体育兴趣;改变传统体育教材内容,养成体育锻炼良好习惯;开展多彩课外体育活动,发展大学生体育能力。%Life-long PE, the most advanced educational idea at present, is increasingly stressed today when quality education and mass fitness plan are promoted in our country. PE in higher school, a joining point between school PE and social PE higher plays an incom-parable role in life-long PE system. As an important part of School PE(PE in elementary school, PE in high school and PE in higher school), PE in high school is the last stage of school PE, the highest level of student PE and the key period of life-long PE of undergradu-ates;and the key period should be stressed in high school with a view to seeking the way to cultivate the consciousness of life-long PE for students such as strengthening the rational understanding of PE, cultivating the PE consciousness of undergraduates, etc.

  7. Unraveling the evolution of uniquely human cognition.

    Science.gov (United States)

    MacLean, Evan L

    2016-06-07

    A satisfactory account of human cognitive evolution will explain not only the psychological mechanisms that make our species unique, but also how, when, and why these traits evolved. To date, researchers have made substantial progress toward defining uniquely human aspects of cognition, but considerably less effort has been devoted to questions about the evolutionary processes through which these traits have arisen. In this article, I aim to link these complementary aims by synthesizing recent advances in our understanding of what makes human cognition unique, with theory and data regarding the processes of cognitive evolution. I review evidence that uniquely human cognition depends on synergism between both representational and motivational factors and is unlikely to be accounted for by changes to any singular cognitive system. I argue that, whereas no nonhuman animal possesses the full constellation of traits that define the human mind, homologies and analogies of critical aspects of human psychology can be found in diverse nonhuman taxa. I suggest that phylogenetic approaches to the study of animal cognition-which can address questions about the selective pressures and proximate mechanisms driving cognitive change-have the potential to yield important insights regarding the processes through which the human cognitive phenotype evolved.

    González-Rodríguez, Pedro; Ilan, Boaz; Kim, Arnold D.

    2016-06-01

    We introduce the one-way radiative transfer equation (RTE) for modeling the transmission of a light beam incident normally on a slab composed of a uniform forward-peaked scattering medium. Unlike the RTE, which is formulated as a boundary value problem, the one-way RTE is formulated as an initial value problem. Consequently, the one-way RTE is much easier to solve. We discuss the relation of the one-way RTE to the Fokker-Planck, small-angle, and Fermi pencil beam approximations. Then, we validate the one-way RTE through systematic comparisons with RTE simulations for both the Henyey-Greenstein and screened Rutherford scattering phase functions over a broad range of albedo, anisotropy factor, optical thickness, and refractive index values. We find that the one-way RTE gives very good approximations for a broad range of optical property values for thin to moderately thick media that have moderately to sharply forward-peaked scattering. Specifically, we show that the error made by the one-way RTE decreases monotonically as the anisotropic factor increases and as the albedo increases. On the other hand, the error increases monotonically as the optical thickness increases and the refractive index mismatch at the boundary increases.

    We describe an ongoing effort to communicate what is known about the Milky Way, and how our understanding of the Galaxy has advanced in recent decades with observations across the electromagnetic spectrum. Our aim is to help students, educators, and the general public understand the structure of the Milky Way, and our location within it. Inspired by the warm reception to our Multiwavelength Milky Way poster (26,000 copies distributed; requested by people in over 50 countries) we created several related products and a new version of the poster. The updated poster contains ten Galactic plane maps and a legend that points out prominent features and objects. The Multiwavelength Milky Way web site at http://adc.gsfc.nasa.gov/mw provides an image browsing capability, links to data files and journal articles, lesson plans and suggested activities for teachers, and a poster order form. We created a slide set comprised of multiwavelength all-sky maps and a ``Multiwavelength Milky Way'' image corresponding to the poster. The Galactic plane maps featured on the poster raise questions in the minds of many non-astronomers: ``Where are we in this picture?'' and ``How do we know what we know?'' To help answer these questions we developed a realistic three-dimensional model of the Milky Way and used state-of-the-art animation techniques to create a 28-minute video called The Milky Way's Invisible Light. The viewer is taken on a tour of the Galaxy that ends at the Sun's location, from which the 3-D model is shown to resemble the Galactic plane surveys depicted on the Multiwavelength Milky Way poster. The video can be ordered on the web at http://space.gsfc.nasa.gov/astro/education/mw_film or from the ASP catalog. The Multiwavelength Milky Way project is sponsored by the Astrophysics Data Facility at NASA's Goddard Space Flight Center.

    Full Text Available Many efforts to improve healthcare safety have focused on redesigning processes of care or retraining clinicians. Far less attention has been focused on the use of new technologies to improve safety. We present the results of a unique collaboration between the VA National Center for Patient Safety (NCPS and the Thayer School of Engineering at Dartmouth College. Each year, the NCPS identifies safety problems across the VA that could be addressed with newly-engineered devices. Teams of Thayer students and faculty participating in a senior design course evaluate and engineer a solution for one of the problems. Exemplar projects have targeted surgical sponge retention, nosocomial infections, surgical site localization, and remote monitoring of hospitalized patients undergoing diagnostic testing and procedures. The program has served as an avenue for engineering students and health care workers to solve problems together. The success of this academic-clinical partnership could be replicated in other settings.

    2013-09-24

    The Food and Drug Administration (FDA) is issuing a final rule to establish a system to adequately identify devices through distribution and use. This rule requires the label of medical devices to include a unique device identifier (UDI), except where the rule provides for an exception or alternative placement. The labeler must submit product information concerning devices to FDA's Global Unique Device Identification Database (GUDID), unless subject to an exception or alternative. The system established by this rule requires the label and device package of each medical device to include a UDI and requires that each UDI be provided in a plain-text version and in a form that uses automatic identification and data capture (AIDC) technology. The UDI will be required to be directly marked on the device itself if the device is intended to be used more than once and intended to be reprocessed before each use.

    2012-01-01

    There is unique and groundbreaking science to be done with a new generation of UV spectrographs that cover wavelengths in the "Lyman Ultraviolet" (LUV; 912 - 1216 Ang). There is no astrophysical basis for truncating spectroscopic wavelength coverage anywhere between the atmospheric cutoff (3100 Ang) and the Lyman limit (912 Ang); the usual reasons this happens are all technical. The unique science available in the LUV includes critical problems in astrophysics ranging from the habitability of exoplanets to the reionization of the IGM. Crucially, the local Universe (z <= 0.1) is entirely closed to many key physical diagnostics without access to the LUV. These compelling scientific problems require overcoming these technical barriers so that future UV spectrographs can extend coverage to the Lyman limit at 912 Ang.

Such injuries presenting in a single or adjacent dual rays have been described in few cases previously. We describe such an injury in adjacent three metatarsals of a polytrauma patient. These injuries are likely to be missed in the initial assessment of a polytrauma patient.

    Full Text Available Classical studies on pre-modern Indian social structure have suggested apparent differences between the Indian caste system and social stratification as one can discern in other parts of the world. However, one needs to question such dogmatic assertions that such vast differences really existed. An endeavor is made in this research paper to reflect on the nature of caste hierarchy in pre-modern India. The caste system forms the significant basis of pre-modern Indian social structure. Early writers conceived the caste system of pre-modern India as something unique to India. An attempt is made to question this application of theory of uniqueness in the case of India.

    2007-01-01

    The uniqueness problem of entire functions concerning weighted sharing was discussed, and the following theorem was proved. Let f and g be two non-constant entire functions, m, n and k three positive integers, and n>2k+4. If Em(1,(f n)(k))= Em(1,(gn)(k)), then either f (z)=c1ecz and g(z)= c2e-cz, or f =tg, where c, c1 and c2 are three constants satisfying (-1)k(c1c2)n(nc)2k=1, and t is a constant satisfying t n=1. The theorem generalizes the result of Fang [Fang ML, Uniqueness and value sharing of entire functions, Computer & Mathematics with Applications, 2002, 44: 823-831].

    We introduce a BCFW shift which can be used to recursively build the full Yang-Mills amplitude as a function of polarization vectors. Furthermore, in line with the recent results of arXiv:1612.02797, we conjecture that the Yang-Mills scattering amplitude is uniquely fixed by locality and demanding the usual asymptotic behavior under a sufficient number of shifts. Unitarity therefore emerges from locality and constructability. We prove this statement at the leading order in the soft expansion.

  11. Evolutionary theory, human uniqueness and the image of God

    Directory of Open Access Journals (Sweden)

    Gijsbert van den Brink

    2012-09-01

    Full Text Available In this article, I examined what might be called the evolutionary argument against human uniqueness and human dignity. After having rehearsed briefly the roots of the classical Judeo- Christian view on human uniqueness and human dignity in the first chapters of Genesis, I went on to explore and delineate the nature of the evolutionary argument against this view. Next, I examined whether Christian theology might widen the concept of imago Dei so as to include other beings as well as humans, thus giving up the idea of human uniqueness. I concluded, however, that this move is deeply problematic. Therefore, I turned to a discussion of some recent attempts to define both human uniqueness and the image of God in theological rather than empirical terms. One of these, which is based on the concept of incarnation, is found wanting, but another one is construed in such a way that it enables us to reconcile the idea of human uniqueness as encapsulated in the doctrine of the imago Dei with contemporary evolutionary theory. Thus, this article can be seen as an exercise in bringing classical Christian theology to terms with evolution, further highlighting this theology’s ongoing vitality.Evolusieteorie, menslike uniekheid and die beeld van God. In hierdie artikel ondersoek ek die sogenaamde evolusionêre argument teen menslike uniekheid en menswaardigheid. Na ‘n kort oorsig oor die oorsprong van die klassieke Joods-Christelike siening van menslike uniekheid en menswaardigheid soos uit die eerste vyf hoofstukke van Genesis blyk, ondersoek en beeld ek die aard van die evolusionêre argument hierteenoor uit. Vervolgens word die vraag ondersoek of die Christelike teologie die konsep van imago Dei sodanig kan verbreed dat dit ook ander wesens behalwe mense kan insluit, waardeur die idee van menslike uniekheid dus prysgegee word. Ek kom egter tot die slotsom dat hierdie skuif hoogs problematies is. Daarom wend ek my tot ’n bespreking van onlangse pogings om

  12. Violence in the School Setting: A School Nurse Perspective.

    2014-01-31

    Violence in schools has become a significant public health risk and is not limited to violent acts committed in the school setting. Violence in homes, neighborhoods, and communities also affects the learning and behaviors of children while at school. School violence, such as shootings, weapons in schools, assaults, fights, bullying; other witnessed violence in non-school settings; and violence as a cultural norm of problem solving can all impact the ability of children to function in school. School nurses serve on the front-line of problem identification and intervene to diminish the effects of violence on both school children as individuals and on populations in schools and the community. This article describes ways in which school nurses deal with violence and concludes with discussion of potential responses to violence, including the school nurse response to violence and implications for other healthcare professionals.

    2015-01-16

    Combining dendritic cell vaccination with the adjuvant effect of a strain of dengue virus may be a way to overcome known tumor immune evasion mechanisms. Dengue is unique among viruses as primary infections carry lower mortality than the common cold, but secondary infections carry significant risk of hypovolemic shock. While current immuno-therapies rely on a single axis of attack, this approach combines physiological (hyperthermic reduction of tumor perfusion), immunological (activation of effector cells of the adaptive and innate immune system), and apoptosis-inducing pathways (sTRAIL) to destroy tumor cells. The premise of using multiple mechanisms of action in synergy with a decline in the ability of the tumor cells to employ resistance methods suggests the potential of this combination approach in cancer immunotherapy.

    In addition to the Affordable Care Act, states are more frequently turning to Medicaid waivers to achieve the "Triple Aim" goals of improving the experience of care, improving population health, and reducing per capita costs. These demonstration waivers provide opportunities to test innovative ways to finance and deliver care. Texas is currently implementing a waiver known as the Transformation and Quality Improvement Program. Its inclusion of public health agencies is a unique approach to a system typically limited to traditional providers. San Antonio Metropolitan Health District is one public health agency taking advantage of this new funding opportunity to implement 6 new or expanded programs targeting health issues of highest priority in this south Texas region. This article discusses the use of Medicaid waivers and the advantages and challenges of public health agency participation.

  15. Objective Nontensor Rheology: Unique Flow Decompositions from Correlated Microscopic Motions

    CERN Document Server

    Chafin, Clifford

    2014-01-01

    The use of continuum mechanics and invariants built from the deviator as an adequate foundation for rheology has been recently disputed by this author. Here we give a specific example of the kind of parcel deformations that are uniquely decomposed by way of microscopic motions into a maximal rotation, a pure shear and an extension. The construction of these equations depends on only one free material parameter but they have no nice form in terms of the operations of vector and tensor calculus which may be why they were overlooked. Although the first order flow is often sufficient to give the rheological information, finite sized parcel deformations can give confusion because of boundary effects, the relevance of which are highly dependent on the global geometry of the experiment.

  3. Arm coordination in octopus crawling involves unique motor control strategies.

    Levy, Guy; Flash, Tamar; Hochner, Binyamin

    2015-05-04

    To cope with the exceptional computational complexity that is involved in the control of its hyper-redundant arms [1], the octopus has adopted unique motor control strategies in which the central brain activates rather autonomous motor programs in the elaborated peripheral nervous system of the arms [2, 3]. How octopuses coordinate their eight long and flexible arms in locomotion is still unknown. Here, we present the first detailed kinematic analysis of octopus arm coordination in crawling. The results are surprising in several respects: (1) despite its bilaterally symmetrical body, the octopus can crawl in any direction relative to its body orientation; (2) body and crawling orientation are monotonically and independently controlled; and (3) contrasting known animal locomotion, octopus crawling lacks any apparent rhythmical patterns in limb coordination, suggesting a unique non-rhythmical output of the octopus central controller. We show that this uncommon maneuverability is derived from the radial symmetry of the arms around the body and the simple pushing-by-elongation mechanism by which the arms create the crawling thrust. These two together enable a mechanism whereby the central controller chooses in a moment-to-moment fashion which arms to recruit for pushing the body in an instantaneous direction. Our findings suggest that the soft molluscan body has affected in an embodied way [4, 5] the emergence of the adaptive motor behavior of the octopus.

    A suite of vast stellar surveys mapping the Milky Way, culminating in the Gaia mission, is revolutionizing the empirical information about the distribution and properties of stars in the Galactic stellar disk. We review and lay out what analysis and modeling machinery needs to be in place to test mechanisms of disk galaxy evolution and to stringently constrain the Galactic gravitational potential, using such Galactic star-by-star measurements. We stress the crucial role of stellar survey selection functions in any such modeling; and we advocate the utility of viewing the Galactic stellar disk as made up from `mono-abundance populations' (MAPs), both for dynamical modeling and for constraining the Milky Way's evolutionary processes. We review recent work on the spatial and kinematical distribution of MAPs, and lay out how further study of MAPs in the Gaia era should lead to a decisively clearer picture of the Milky Way's dark matter distribution and formation history.

    Surgically treated patients with arteriovenous malformations (AVMs) are considered cured when the postoperative angiogram proves complete resection. However, despite no residual nidus or early draining vein on postoperative angiogram, rare instances of AVM recurrence have been reported in adults. In this paper, the authors present a case of a 24-year-old woman with asymptomatic double recurrence of her cerebral AVM after angiographically proven complete resection. To the authors' knowledge, this patient represents the first case with double de novo asymptomatic recurrence of Spetzler-Martin grade I AVM. Also, she represents the first case with unique AVM criteria in each recurrence.

    Analysis to discriminate Centauro events from normal events is made without previous identification of secondary emitted particles. For this purpose their energy and derived quantities like distance from the center of momenta it were mainly used. As a result we found in a sample of (280+87) experimental events only 3 were compatible with 5 Centauro events, but none of them dad a high content of hadrons, characteristic of Centauro events. With this result we are confident about the uniqueness of Centauro events, especially for two events that have vertex directly determined. Comparing with some interaction models features we depict a possible scenario to explain Centauro events.

    It is shown that the only functionals, within a natural class, which are monotonic in time for all solutions of the vacuum Einstein equations admitting a smooth ``piece'' of conformal null infinity Scri, are those depending on the metric only through a specific combination of the Bondi `mass aspect' and other next--to--leading order terms in the metric. Under the extra condition of passive BMS invariance, the unique such functional (up to a multiplicative factor) is the Trautman--Bondi energy. It is also shown that this energy remains well-defined for a wide class of `polyhomogeneous' metrics.

    Consider a market where producers submit supply functions to a procurement auction with uncertain demand, e.g. an electricity auction. In the Supply Function Equilibrium (SFE), every firm commits to the supply function that maximises expected profit in the one-shot game given the supply functions of competitors. A basic weakness of the SFE is the presence of multiple equilibria. This paper shows that with (i) symmetric producers, (ii) perfectly inelastic demand, (iii) a price cap, and (iv) capacity constraints that bind with a positive probability, there exists a unique, symmetric SFE.

    2007-01-01

    We consider two-way wire-tap channels, where two users are communicating with each other in the presence of an eavesdropper, who has access to the communications through a multiple-access channel. We find achievable rates for two different scenarios, the Gaussian two-way wire-tap channel, (GTW-WT), and the binary additive two-way wire-tap channel, (BATW-WT). It is shown that the two-way channels inherently provide a unique advantage for wire-tapped scenarios, as the users know their own transmitted signals and in effect help encrypt the other user's messages, similar to a one-time pad. We compare the achievable rates to that of the Gaussian multiple-access wire-tap channel (GMAC-WT) to illustrate this advantage.

    Full Text Available This article describes the ways in which homework in the subject of Spanish travels from classrooms to students’ homes in first and second grade. The research is based on an ethnographic perspective that can show how homework is an object of school culture, which is constructed and re-constructed by educational actors, leading to various appropriations of homework according to the social networks and relationships involved as it navigates between school and home. Therefore, homework can also be viewed as a series of cultural practices that simultaneously enable and impeded the links between school and family. The manner in which homework navigates will vary depending on school and family contexts. Family members responsible for picking up and supporting children are a major point of reference, as are the diverse cultural practices through which the teachers make explicit the homework and the supports used for its transit. This article is published in Spanish.

  14. Unmanned Aerial Vehicles unique cost estimating requirements

    Science.gov (United States)

    Malone, P.; Apgar, H.; Stukes, S.; Sterk, S.

    Unmanned Aerial Vehicles (UAVs), also referred to as drones, are aerial platforms that fly without a human pilot onboard. UAVs are controlled autonomously by a computer in the vehicle or under the remote control of a pilot stationed at a fixed ground location. There are a wide variety of drone shapes, sizes, configurations, complexities, and characteristics. Use of these devices by the Department of Defense (DoD), NASA, civil and commercial organizations continues to grow. UAVs are commonly used for intelligence, surveillance, reconnaissance (ISR). They are also use for combat operations, and civil applications, such as firefighting, non-military security work, surveillance of infrastructure (e.g. pipelines, power lines and country borders). UAVs are often preferred for missions that require sustained persistence (over 4 hours in duration), or are “ too dangerous, dull or dirty” for manned aircraft. Moreover, they can offer significant acquisition and operations cost savings over traditional manned aircraft. Because of these unique characteristics and missions, UAV estimates require some unique estimating methods. This paper describes a framework for estimating UAV systems total ownership cost including hardware components, software design, and operations. The challenge of collecting data, testing the sensitivities of cost drivers, and creating cost estimating relationships (CERs) for each key work breakdown structure (WBS) element is discussed. The autonomous operation of UAVs is especially challenging from a software perspective.

  15. Event Segmentation Ability Uniquely Predicts Event Memory

    Sargent, Jesse Q.; Zacks, Jeffrey M.; Hambrick, David Z.; Zacks, Rose T.; Kurby, Christopher A.; Bailey, Heather R.; Eisenberg, Michelle L.; Beck, Taylor M.

    2013-01-01

    Memory for everyday events plays a central role in tasks of daily living, autobiographical memory, and planning. Event memory depends in part on segmenting ongoing activity into meaningful units. This study examined the relationship between event segmentation and memory in a lifespan sample to answer the following question: Is the ability to segment activity into meaningful events a unique predictor of subsequent memory, or is the relationship between event perception and memory accounted for by general cognitive abilities? Two hundred and eight adults ranging from 20 to 79 years old segmented movies of everyday events and attempted to remember the events afterwards. They also completed psychometric ability tests and tests measuring script knowledge for everyday events. Event segmentation and script knowledge both explained unique variance in event memory above and beyond the psychometric measures, and did so as strongly in older as in younger adults. These results suggest that event segmentation is a basic cognitive mechanism, important for memory across the lifespan. PMID:23942350

    We experimentally study Lowest Unique Integer Games (LUIGs) to determine if and how subjects self-organize into different behavioral classes. In a LUIG, N(≥ 3) players submit a positive integer up to M and the player choosing the smallest number not chosen by anyone else wins. LUIGs are simplified versions of real systems such as Lowest/Highest Unique Bid Auctions that have been attracting attention from scholars, yet experimental studies are scarce. Furthermore, LUIGs offer insights into choice patterns that can shed light on the alleviation of congestion problems. Here, we consider four LUIGs with N = { 3 , 4 } and M = { 3 , 4 } . We find that (a) choices made by more than 1/3 of subjects were not significantly different from what a symmetric mixed-strategy Nash equilibrium (MSE) predicts; however, (b) subjects who behaved significantly differently from what the MSE predicts won the game more frequently. What distinguishes subjects was their tendencies to change their choices following losses.

  15. The core and unique proteins of haloarchaea

    Directory of Open Access Journals (Sweden)

    Capes Melinda D

    2012-01-01

    Full Text Available Abstract Background Since the first genome of a halophilic archaeon was sequenced in 2000, biologists have been advancing the understanding of genomic characteristics that allow for survival in the harsh natural environments of these organisms. An increase in protein acidity and GC-bias in the genome have been implicated as factors in tolerance to extreme salinity, desiccation, and high solar radiation. However, few previous attempts have been made to identify novel genes that would permit survival in such extreme conditions. Results With the recent release of several new complete haloarchaeal genome sequences, we have conducted a comprehensive comparative genomic analysis focusing on the identification of unique haloarchaeal conserved proteins that likely play key roles in environmental adaptation. Using bioinformatic methods, we have clustered 31,312 predicted proteins from nine haloarchaeal genomes into 4,455 haloarchaeal orthologous groups (HOGs. We assigned likely functions by association with established COG and KOG databases in NCBI. After identifying homologs in four additional haloarchaeal genomes, we determined that there were 784 core haloarchaeal protein clusters (cHOGs, of which 83 clusters were found primarily in haloarchaea. Further analysis found that 55 clusters were truly unique (tucHOGs to haloarchaea and qualify as signature proteins while 28 were nearly unique (nucHOGs, the vast majority of which were coded for on the haloarchaeal chromosomes. Of the signature proteins, only one example with any predicted function, Ral, involved in desiccation/radiation tolerance in Halobacterium sp. NRC-1, was identified. Among the core clusters, 33% was predicted to function in metabolism, 25% in information transfer and storage, 10% in cell processes and signaling, and 22% belong to poorly characterized or general function groups. Conclusion Our studies have established conserved groups of nearly 800 protein clusters present in all

  16. Pinning down the Milky Way's spin

    Science.gov (United States)

    2008-09-01

    New, very precise measurements have shown that the rotation of the Milky Way is simpler than previously thought. A remarkable result from the most successful ESO instrument HARPS, shows that a much debated, apparent 'fall' of neighbourhood Cepheid stars towards our Sun stems from an intrinsic property of the Cepheids themselves. First Light of the PRIMA Instrument ESO PR Photo 30/08 Cepheids in the Solar Neighbourhood The result, obtained by a group of astrophysicists led by Nicolas Nardetto, will soon appear in the journal Astronomy & Astrophysics. Since Henrietta Leavitt's discovery of their unique properties in 1912, the class of bright, pulsating stars known as Cepheids has been used as a distance indicator. Combined with velocity measurements, the properties of Cepheids are also an extremely valuable tool in investigations of how our galaxy, the Milky Way, rotates. "The motion of Milky Way Cepheids is confusing and has led to disagreement among researchers," says Nardetto. "If the rotation of the Galaxy is taken into account, the Cepheids appear to 'fall' towards the Sun with a mean velocity of about 2 km/s." A debate has raged for decades as to whether this phenomenon was truly related to the actual motion of the Cepheids and, consequently, to a complicated rotating pattern of our galaxy, or if it was the result of effects within the atmospheres of the Cepheids. Nardetto and his colleagues observed eight Cepheids with the high precision HARPS spectrograph, attached to the 3.6-m ESO telescope at La Silla, 2400 m up in the mountains of the Chilean Atacama Desert. HARPS, or the High Accuracy Radial Velocity Planetary Searcher, is best known as a very successful planet hunter, but it can also be used to resolve other complicated cases, where its ability to determine radial velocities - the speed with which something is moving towards or away from us - with phenomenally high accuracy is invaluable. "Our observations show that this apparent motion towards us almost

  18. Conditional and Unique Coloring of Graphs

    CERN Document Server

    Reddy, P Venkata Subba

    2011-01-01

    For integers $k, r > 0$, a conditional $(k,r)$-coloring of a graph $G$ is a proper $k$-coloring of the vertices of $G$ such that every vertex $v$ of degree $d(v)$ in $G$ is adjacent to at least $\\min\\{r, d(v)\\}$ differently colored vertices. Given $r$, the smallest integer $k$ for which $G$ has a conditional $(k,r)$-coloring is called the $r$th order conditional chromatic number $\\chi_r(G)$ of $G$. We give results (exact values or bounds for $\\chi_r(G)$, depending on $r$) related to the conditional coloring of some graphs. We introduce \\emph{unique conditional colorability} and give some related results. (Keywords. cartesian product of graphs; conditional chromatic number; gear graph; join of graphs.)

  19. Computational Transition at the Uniqueness Threshold

    CERN Document Server

    Sly, Allan

    2010-01-01

    The hardcore model is a model of lattice gas systems which has received much attention in statistical physics, probability theory and theoretical computer science. It is the probability distribution over independent sets $I$ of a graph weighted proportionally to $\\lambda^{|I|}$ with fugacity parameter $\\lambda$. We prove that at the uniqueness threshold of the hardcore model on the $d$-regular tree, approximating the partition function becomes computationally hard on graphs of maximum degree $d$. Specifically, we show that unless NP$=$RP there is no polynomial time approximation scheme for the partition function (the sum of such weighted independent sets) on graphs of maximum degree $d$ for fugacity $\\lambda_c(d) 0$. Weitz produced an FPTAS for approximating the partition function when $0<\\lambda < \\lambda_c(d)$ so this result demonstrates that the computational threshold exactly coincides with the statistical physics phase transition thus confirming the main conjecture of [28]. We further analyze the s...

  20. Organizing the spatially and temporally unique hydrosphere

    Berghuijs, Wouter

    2016-04-01

    Growing anthropogenic activity is quickly changing the hydrosphere. Panta Rhei calls for improved understanding of changing hydrosphere dynamics in their connection with human systems. I argue that progress within the Panta Rhei initiative is strongly limited by the absence of hydrological principles that help to organise our spatially and temporally unique hydrosphere; without guiding principles (e.g. classification systems) hydrology will continue to be a case study dominated science that will have a hard time to efficiently improve understanding, estimation and prediction of human affected systems. Exposing such organising principles should not be considered as a step backwards into the recent PUB decade. Instead, it should be regarded as an exciting scientific challenge that is becoming increasingly relevant now the hydrosphere is quickly changing.

    Bachy, Romain; Dias, Jérôme; Alleysson, David; Bonnardel, Valérie

    2012-02-01

    The hue discrimination curve (HDC) that characterizes performances over the entire hue circle was determined by using sinusoidally modulated spectral power distributions of 1.5 c/300 nm with fixed amplitude and twelve reference phases. To investigate relationship between hue discrimination and appearance, observers further performed a free color naming and unique hue tasks. The HDC consistently displayed two minima and two maxima; discrimination is optimal at the yellow/orange and blue/magenta boundaries and pessimal in green and in the extra-spectral magenta colors. A linear model based on Müller zone theory correctly predicts a periodical profile but with a phase-opponency (minima/maxima at 180° apart) which is inconsistent with the empirical HDC's profile.

    A concentrated fish soup could be gelled in the winter and re-solled upon heating. In contrast, some synthetic copolymers exhibit an inverse sol-gel transition with spontaneous physical gelation upon heating instead of cooling. If the transition in water takes place below the body temperature and the chemicals are biocompatible and biodegradable, such gelling behavior makes the associated physical gels injectable biomaterials with unique applications in drug delivery and tissue engineering etc. Various therapeutic agents or cells can be entrapped in situ and form a depot merely by a syringe injection of their aqueous solutions at target sites with minimal invasiveness and pain. This tutorial review summarizes and comments on this soft matter, especially thermogelling poly(ethylene glycol)-(biodegradable polyester) block copolymers. The main types of injectable hydrogels are also briefly introduced, including both physical gels and chemical gels.

  8. The bacterial magnetosome: a unique prokaryotic organelle.

    Science.gov (United States)

    Lower, Brian H; Bazylinski, Dennis A

    2013-01-01

    The bacterial magnetosome is a unique prokaryotic organelle comprising magnetic mineral crystals surrounded by a phospholipid bilayer. These inclusions are biomineralized by the magnetotactic bacteria which are ubiquitous, aquatic, motile microorganisms. Magnetosomes cause cells of magnetotactic bacteria to passively align and swim along the Earth's magnetic field lines, as miniature motile compass needles. These specialized compartments consist of a phospholipid bilayer membrane surrounding magnetic crystals of magnetite (Fe3O4) or greigite (Fe3S4). The morphology of these membrane-bound crystals varies by species with a nominal magnetic domain size between 35 and 120 nm. Almost all magnetotactic bacteria arrange their magnetosomes in a chain within the cell there by maximizing the magnetic dipole moment of the cell. It is presumed that magnetotactic bacteria use magnetotaxis in conjunction with chemotaxis to locate and maintain an optimum position for growth and survival based on chemistry, redox and physiology in aquatic habitats with vertical chemical concentration and redox gradients. The biosynthesis of magnetosomes is a complex process that involves several distinct steps including cytoplasmic membrane modifications, iron uptake and transport, initiation of crystallization, crystal maturation and magnetosome chain formation. While many mechanistic details remain unresolved, magnetotactic bacteria appear to contain the genetic determinants for magnetosome biomineralization within their genomes in clusters of genes that make up what is referred to as the magnetosome gene island in some species. In addition, magnetosomes contain a unique set of proteins, not present in other cellular fractions, which control the biomineralization process. Through the development of genetic systems, proteomic and genomic work, and the use of molecular and biochemical tools, the functions of a number of magnetosome membrane proteins have been demonstrated and the molecular

    Gaia is an ESA cornerstone mission set to revolutionise our understanding of the Milky Way. Gaia is scheduled for launch in 2013, and is designed to map over one billion stars with three instruments to collect astrometric, photometric and spectroscopic data on stars in the Milky Way and in galaxies belonging to the Local Group, distant galaxies, quasars and solar system objects. Gaia builds on the expertise established in Europe through the successful ESA Hipparcos mission. This contribution provides updated information on the Gaia mission and notes the science performance capability of the mission. The GREAT (Gaia Research for European Astronomy Training) research network, which is taking a role in promoting scientific networking of the community building awareness and readiness in advance of the Gaia launch, is discussed.

  12. Wrong way recollement for schemes

    OpenAIRE

    Jorgensen, Peter

    2005-01-01

    A recollement of triangulated categories makes it possible to view one such category as being glued together from two others. The prototypical example is that D(X), a suitable derived category of sheaves on the topological space X, has a recollement in terms of D(Z) and D(U) when Z is a closed subset of X and U is the open complement. This note gives a different, "wrong way" recollement in the scheme case.

  13. Ways of Viewing Pictorial Plasticity

    2017-03-01

    Full Text Available The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture is physically flat. Although various viewing modes have been proposed in the literature, their effects have never been compared. In the current study, we compared three viewing modes: monocular blur, synoptic viewing, and free viewing (using a placebo synopter. By designing a physical embodiment that was indistinguishable for the three experimental conditions, we kept observers naïve with respect to the differences between them; 197 observers participated in an experiment where the three viewing modes were compared by performing a rating task. Results indicate that synoptic viewing causes the largest plastic effect. Monocular blur scores lower than synoptic viewing but is still rated significantly higher than the baseline conditions. The results strengthen the idea that synoptic viewing is not due to a placebo effect. Furthermore, monocular blur has been verified for the first time as a way of experiencing the plastic effect, although the effect is smaller than synoptic viewing. We discuss the results with respect to the theoretical basis for the plastic effect. We show that current theories are not described with sufficient details to explain the differences we found.

    Full Text Available We propose a public IR variability survey, named \\Vista Variables in the V a L ctea" (V V V , of the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. This would take 1920 hours, covering 109 point sources within an area of 520 sq deg, including 33 known globular clusters and 350 open clusters. The nal products will be a deep IR atlas in 5 passbands and a catalogue of 106 variable point sources. These will produce a 3-D map of the surveyed region (unlike single-epoch surveys that only give 2-D maps using well-understood primary distance indicators such as RR Lyrae stars. It will yield important information on the ages of the populations. The observations will be combined with data from MACHO, OGLE, EROS, VST, SPITZER, HST, CHANDRA, INTEGRAL, and ALMA for a complete understanding of the variable sources in the inner Milky Way. Several important implications for the history of the Milky Way, for globular cluster evolution, for the population census of the bulge and center, and for pulsation theory would follow from this survey.

    Sapropel from inland Russian water reservoirs is becoming a popular raw material for medicinal purposes, production of sorbents, organomineral fertilizers, and food supplements. A comparative study of the granulometric and biological properties of humic substances obtained from sapropel in a typical way and using ultrasonic treatment of the relevant reaction masses was performed at the Institute of Limnology of the Russian Academy of Sciences. It is shown that the humic substances of sapropel with an increased content of nanoparticles used as veterinary preparations lead to a significant economic effect without using imported preparations.

    March 23, Wednesday, Wuhan. It was a raining and cloudy day. One month passed but still more than 20 students had yet registered in Lingzhi Elementary School in Jianghan District, Wuhan, capital city of central Hubei Province. Zhu Zhongfan habitually looked out to the stairway of the building. “Whenever a new semester begins, a dozen of students will not come. They either go back to their hometowns or transfer to other school or even drop out.” Zhu, 49 years old, is the headmaster of the school. He began teaching at 19 and founded this school in 1999. Currently, there are 406 registered students, most of which are children of migrant workers from the countryside. As it is extremely hard to find a cheap place for school, Zhu had to locate his school on the roof of a vegetable fair building. Everyday, student's reciting of textbooks mixes with shouting of vendors, orchestrating unique symphonic melodies.

    In the last decades, the demand and acknowledged importance of science outreach, in general and geophysics in particular, has grown, as demonstrated by many international and national projects and other activities performed by research institutes. The National Institute for Earth Physics (NIEP) from Romania is the leading national institution on earthquake monitoring and research, having at the same time a declared focus on informing and educating a wide audience about geosciences and especially seismology. This is more than welcome, since Romania is a very active country from a seismological point of view, but not too reactive when it comes to diminishing the possible effect of a major earthquake. Over the last few decades, the country has experienced several major earthquakes which have claimed thousands of lives and millions in property damage (1940; 1977; 1986 and 1990 Vrancea earthquakes). In this context, during a partnership started in 2014 together with the National Art University and Siveco IT company, a group of researchers from NIEP initiated the MOBile Earthquake Exhibition (MOBEE) project. The main goal was to design a portable museum to bring on the road educational activities focused on seismology, seismic hazard and Earth science. The exhibition is mainly focused on school students of all ages as it explains the main topics of geophysics through a unique combination of posters, digital animations and apps, large markets and exciting hand-on experiments, 3D printed models and posters. This project is singular in Romania and aims to transmit properly reviewed actual information, regarding the definition of earthquakes, the way natural hazards can affect people, buildings and the environment and the measures to be taken for prevent an aftermath. Many of the presented concepts can be used by teachers as a complementary way of demonstrating physics facts and concepts and explaining processes that shape the dynamic Earth features.

    More and more companies struggle with growing competition by introducing improvements into every aspect of performance. But the treadmill keeps moving faster, the companies keep working harder, and results improve slowly or not at all. The problem here is not the improvement programs. The problem is that the whole burden of change typically rests on so few people. Companies achieve real agility only when every function and process--when every person--is able and eager to rise to every challenge. This type and degree of fundamental change, commonly called revitalization or transformation, is what many companies seek but rarely achieve because they have never before identified the factors that produce sustained transformational change. The authors identify three interventions that will restore companies to vital agility and then keep them in good health: incorporating employees fully into the principal business challenges facing the company, leading the organization in a different way in order to sharpen and maintain incorporation and constructive stress, and instilling mental disciplines that will make people behave differently and then help them sustain their new behavior. The authors discovered these basic sources of revitalization by tracking the change efforts of Sears, Roebuck & Company, Royal Dutch Shell, and the United States Army. The organizations used these interventions to alter the way their people experienced their own power and identity, as well as the way they dealt with conflict and learning. As at Sears, Shell, and the U.S. Army, any major shift in those four elements will create a landmark shift in any organization's operating state or culture.

    A teaching/learning strategy that I have developed over the years for high school students involves the use of photographic images of ordinary objects or scenes to help engage students in the intrigue and beauty of physics. The images help focus classroom discussions, raise curiosity levels among students, and promote creativity of thinking. The photographs can be used in a variety of ways, including assessment, framing discussions, homework assignment, and constructive classroom games. This presentation will describe the various ways photography can be used and will model some techniques. Dozens of ``physics images'' will be shown.

  7. Arachnoiditis ossificans and syringomyelia: A unique presentation

    Science.gov (United States)

    Opalak, Charles F.; Opalak, Michael E.

    2015-01-01

    Background: Arachnoiditis ossificans (AO) is a rare disorder that was differentiated from leptomeningeal calcification by Kaufman and Dunsmore in 1971. It generally presents with progressive lower extremity myelopathy. Though the underlying etiology has yet to be fully described, it has been associated with various predisposing factors including vascular malformations, previous intradural surgery, myelograms, and adhesive arachnoiditis. Associated conditions include syringomyelia and arachnoid cyst. The preferred diagnostic method is noncontrast computed tomography (CT). Surgical intervention is still controversial and can include decompression and duroplasty or durotomy. Case Description: The authors report the case of a 62-year-old male with a history of paraplegia who presented with a urinary tract infection and dysautonomia. His past surgical history was notable for a C4–C6 anterior fusion and an intrathecal phenol injection for spasticity. A magnetic resonance image (MR) also demonstrated a T6-conus syringx. At surgery, there was significant ossification of the arachnoid/dura, which was removed. After a drain was placed in the syrinx, there was a significant neurologic improvement. Conclusion: This case demonstrates a unique presentation of AO and highlights the need for CT imaging when a noncommunicating syringx is identified. In addition, surgical decompression can achieve good results when AO is associated with concurrent compressive lesions. PMID:26693389

    Full Text Available Abstract Background Amyloid deposition in heart is a common occurrence in systemic amyloidosis. But localised valvular amyloid deposits are very uncommon. It was only in 1922 that the cases of valvular amyloidosis were reported. Then in 1980, Goffin et al reported another type of valvular amyloidosis, which he called the dystrophic valvular amyloidosis. We report a case of aortic valve amyloidosis which is different from the yet described valvular amyloidosis. Case presentation A 72 years old gentleman underwent urgent aortic valve replacement. Intraoperatively, a lesion was found attached to the inferior surface of his bicuspid aortic valve. Histopathology examination of the valve revealed that the lesion contained amyloid deposits, identified as AL amyloidosis. The serum amyloid A protein (SAP scan was normal and showed no evidence of systemic amyloidosis. The ECG and echocardiogram were not consistent with cardiac amyloidosis. Conclusion Two major types of cardiac amyloidosis have been described in literature: primary-myelomatous type (occurs with systemic amyolidosis, and senile type(s. Recently, a localised cardiac dystrophic valvular amyloidosis has been described. In all previously reported cases, there was a strong association of localised valvular amyloidosis with calcific deposits. Ours is a unique case which differs from the previously reported cases of localised valvular amyloidosis. In this case, the lesion was not associated with any scar tissue. Also there was no calcific deposit found. This may well be a yet unknown type of isolated valvular amyloidosis.

  9. Unique Ganglioside Recognition Strategies for Clostridial Neurotoxins

    Energy Technology Data Exchange (ETDEWEB)

    Benson, Marc A.; Fu, Zhuji; Kim, Jung-Ja P.; Baldwin, Michael R. (MCW); (UMC)

    2012-03-15

    Botulinum neurotoxins (BoNTs) and tetanus neurotoxin are the causative agents of the paralytic diseases botulism and tetanus, respectively. The potency of the clostridial neurotoxins (CNTs) relies primarily on their highly specific binding to nerve terminals and cleavage of SNARE proteins. Although individual CNTs utilize distinct proteins for entry, they share common ganglioside co-receptors. Here, we report the crystal structure of the BoNT/F receptor-binding domain in complex with the sugar moiety of ganglioside GD1a. GD1a binds in a shallow groove formed by the conserved peptide motif E ... H ... SXWY ... G, with additional stabilizing interactions provided by two arginine residues. Comparative analysis of BoNT/F with other CNTs revealed several differences in the interactions of each toxin with ganglioside. Notably, exchange of BoNT/F His-1241 with the corresponding lysine residue of BoNT/E resulted in increased affinity for GD1a and conferred the ability to bind ganglioside GM1a. Conversely, BoNT/E was not able to bind GM1a, demonstrating a discrete mechanism of ganglioside recognition. These findings provide a structural basis for ganglioside binding among the CNTs and show that individual toxins utilize unique ganglioside recognition strategies.

  10. Unique biosynthesis of sesquarterpenes (C35 terpenes).

    Science.gov (United States)

    Sato, Tsutomu

    2013-01-01

    To the best of my knowledge, only 19 cyclic and 8 linear C35 terpenes have been identified to date, and no family name was assigned to this terpene class until recently. In 2011, it was proposed that these C35 terpenes should be called sesquarterpenes. This review highlights the biosynthesis of two kinds of sesquarterpenes (C35 terpenes) that are produced via cyclization of a linear C35 isoprenoid in Bacillus and Mycobacterium species. In Bacillus species, a new type of terpene cyclase that has no sequence homology with any known terpene synthases, as well as a bifunctional terpene cyclase that biosynthesizes two classes of cyclic terpenes with different numbers of carbons as natural products, have been identified. On the other hand, in Mycobacterium species, the first bifunctional Z-prenyltransferase has been found, but a novel terpene cyclase and a unique polyprenyl reductase remain unidentified. The identification of novel enzyme types should lead to the discovery of many homologous enzymes and their products including novel natural compounds. On the other hand, many enzymes responsible for the biosynthesis of natural products have low substrate specificities in vitro. Therefore, to find novel natural products present in organisms, the multifunctionality of enzymes in the biosynthetic pathway of natural products should be analyzed.

    The primary objective of this study was to evaluate the existing conditions and the stability of a mining site in which the unique features of seismicity, mining activity, hydrological conditions, geological con-ditions, environmental conditions, and future development plans were considered. In particular, the potential subsidence locations near the proposed construction site, the effects of mining boundary profile, and the influence scope of the mining activity on the neighboring areas were investigated using the finite element method. The study results indicate:(1) the overlying sandstone layer to the coal layer is the key to the stability of the mining roof; (2) the broken boundary has the most effect, followed by the arc boundary and linear boundary; (3) the safe distance from the mining boundary should be at least 400 m if the proposed structure is to be built near an active mining site. Other relevant engineering rec-ommendations are also proposed. The concluded results from this study may serve as a guide to other similar sites in the world.

    2011-01-01

    Suppose you find the same username on different online services, what is the probability that these usernames refer to the same physical person? This work addresses what appears to be a fairly simple question, which has many implications for anonymity and privacy on the Internet. One possible way of estimating this probability would be to look at the public information associated to the two accounts and try to match them. However, for most services, these information are chosen by the users themselves and are often very heterogeneous, possibly false and difficult to collect. Furthermore, several websites do not disclose any additional public information about users apart from their usernames (e.g., discus- sion forums or Blog comments), nonetheless, they might contain sensitive information about users. This paper explores the possibility of linking users profiles only by looking at their usernames. The intuition is that the probability that two usernames refer to the same physical person strongly depends on t...

    Directory of Open Access Journals (Sweden)

    Robert W. McMeekin

    2003-05-01

    Full Text Available The study proposes: (1 that the institutional climate in schools, which includes formal rules, informal rules, mechanisms for enforcing both kinds of rules, clear objectives and an atmosphere of cooperation and trust, has a strong influence on school performance; (2 that “networks” of schools such as the Accelerated Schools Project in the U.S. and the Fe y Alegría schools in Latin America help improve school performance in a variety of ways, and have been successful in providing good education to disadvantaged children; and (3 that one of the reasons some networks are successful is that they promote the creation of sound institutional environments in member schools. The argument draws on New Institutional Economics and especially on the role of institutions inside school organizations in reducing agency problems and facilitating transactions between actors in school communities. Three examples of networks with a specific orientation toward improving equity—the Matte Schools of Santiago, Chile, the Fe y Alegría schools in multiple Latin American countries, and the Accelerated Schools Project in the U.S.—are presented and analyzed in terms of how they influence intra-organizational institutions.

The INL’s Systems Engineering organization supports all of the various programs under this wide array of missions. As with any multifaceted organization, strategic planning is essential to establishing a consistent culture and a value discipline throughout all levels of the enterprise. While an organization can pursue operational excellence, product leadership or customer intimacy, it is extremely difficult to excel or achieve best-in-class at all three. In fact, trying to do so has resulted in the demise of a number of organizations given the very intricate balancing act that is necessary. The INL’s Systems Engineering Department has chosen to focus on customer intimacy where the customer’s needs are first and foremost and a more total solution is the goal. Frequently a total solution requires the employment of specialized tools to manage system complexity. However, it is only after understanding customer needs that tool selection and use would be pursued. This results in using both commercial-off-the-shelf (COTS) tools and, in some cases, requires internal development of specialized tools. This paper describes how a unique systems engineering capability, through the development of customized tools, evolved as a result of this customer-focused culture. It also addresses the need for a common information model or analysis framework and presents an overview of the tools developed to manage and display relationships between entities, support trade studies through the application of utility theory, and facilitate the development of a technology roadmap to manage system risk and uncertainty.

    The hybrid pathway for heme biosynthesis in the malarial parasite proposes the involvement of parasite genome-coded enzymes of the pathway localized in different compartments such as apicoplast, mitochondria, and cytosol. However, knowledge on the functionality and localization of many of these enzymes is not available. In this study, we demonstrate that porphobilinogen deaminase encoded by the Plasmodium falciparum genome (PfPBGD) has several unique biochemical properties. Studies carried out with PfPBGD partially purified from parasite membrane fraction, as well as recombinant PfPBGD lacking N-terminal 64 amino acids expressed and purified from Escherichia coli cells (DeltaPfPBGD), indicate that both the proteins are catalytically active. Surprisingly, PfPBGD catalyzes the conversion of porphobilinogen to uroporphyrinogen III (UROGEN III), indicating that it also possesses uroporphyrinogen III synthase (UROS) activity, catalyzing the next step. This obviates the necessity to have a separate gene for UROS that has not been so far annotated in the parasite genome. Interestingly, DeltaPfP-BGD gives rise to UROGEN III even after heat treatment, although UROS from other sources is known to be heat-sensitive. Based on the analysis of active site residues, a DeltaPfPBGDL116K mutant enzyme was created and the specific activity of this recombinant mutant enzyme is 5-fold higher than DeltaPfPBGD. More interestingly, DeltaPfPBGDL116K catalyzes the formation of uroporphyrinogen I (UROGEN I) in addition to UROGEN III, indicating that with increased PBGD activity the UROS activity of PBGD may perhaps become rate-limiting, thus leading to non-enzymatic cyclization of preuroporphyrinogen to UROGEN I. PfPBGD is localized to the apicoplast and is catalytically very inefficient compared with the host red cell enzyme.

  5. Counterconformity: an attribution model of adolescents' uniqueness-seeking behaviors in dressing.

    2008-01-01

    This article explores how an attribution model will illustrate uniqueness-seeking behavior in dressing in the Taiwanese adolescent subculture. The study employed 443 senior high school students. Results show that the tendency of uniqueness-seeking behavior in dressing is moderate. However, using cluster analysis to segment the counterconformity behavior of the subjects, the study demonstrates that there are two conspicuous types of segmentation "markets": rubber stamp and self-determined. The attribution models investigate the susceptibilities to informational and normative influence which have different direction impacts and weights on the adolescents' counterconformity behavior. More interestingly, path analyses indicate that consumer self-confidence mediates the relationship between informational influence and counterconformity behavior only on the rubber stamp type. This study then discusses how the adolescent consumers' need for uniqueness could be used in better understanding consumer behavior and the role consumption plays in their expression of identity.

    2015-08-01

    We describe a dual-process theory of how individuals estimate the probabilities of unique events, such as Hillary Clinton becoming U.S. President. It postulates that uncertainty is a guide to improbability. In its computer implementation, an intuitive system 1 simulates evidence in mental models and forms analog non-numerical representations of the magnitude of degrees of belief. This system has minimal computational power and combines evidence using a small repertoire of primitive operations. It resolves the uncertainty of divergent evidence for single events, for conjunctions of events, and for inclusive disjunctions of events, by taking a primitive average of non-numerical probabilities. It computes conditional probabilities in a tractable way, treating the given event as evidence that may be relevant to the probability of the dependent event. A deliberative system 2 maps the resulting representations into numerical probabilities. With access to working memory, it carries out arithmetical operations in combining numerical estimates. Experiments corroborated the theory's predictions. Participants concurred in estimates of real possibilities. They violated the complete joint probability distribution in the predicted ways, when they made estimates about conjunctions: P(A), P(B), P(A and B), disjunctions: P(A), P(B), P(A or B or both), and conditional probabilities P(A), P(B), P(B|A). They were faster to estimate the probabilities of compound propositions when they had already estimated the probabilities of each of their components. We discuss the implications of these results for theories of probabilistic reasoning.

The log is more like a stiffness accompanied by a metaphoric chain saw buzz from my apparently loud snoring. Insomnia, habitual sleeplessness, fortunately is not a friend of mine, but that’s because I have experimented with different ways to make my forty winks longer, waken with an attitude to seize the day and not feel tired an hour after breakfast.

    This paper explores the essential features of recovery and the need for an existential approach in psychiatry. The biopsychosocial model often fails to sufficiently validate the existential suffering of patients. We review the major principles of recovery and the philosophical and psychiatric principles of existentialism. The ontological or intrinsic existential issues of death, isolation, freedom and meaninglessness are described and their manifestations are explored in clinical syndromes. When ultimate existential concerns are recognised, patients have an opportunity to understand their life on a deeper level that is not defined as a medical disorder but as a part of human existence. Understanding that existential concerns underlie a great deal of human behaviour helps to free patients from the stigma of psychiatric labels. An existential approach is a humanistic way toward recovery.

    . On this basis, we hypothesized that dietary nitrate (NO3-) could influence the brain's hemodynamic response to neuronal stimulation. In the present study, 20 healthy male participants were given either sodium nitrate (NaNO3) or sodium chloride (NaCl) (saline placebo) in a crossover study and were shown visual.......9±4%, respectively), and the variation across activated voxels of both measures decreased (12.3±4% and 15.3±7%, respectively). The baseline cerebral blood flow was not affected by nitrate. Our experiments demonstrate, for the first time, that dietary nitrate may modulate the local cerebral hemodynamic response...... to stimuli. A faster and smaller BOLD response, with less variation across local cortex, is consistent with an enhanced hemodynamic coupling during elevated nitrate intake. These findings suggest that dietary patterns, via the nitrate-nitrite-NO pathway, may be a potential way to affect key properties...

  11. Ways of standardizing mining regulations

    Macionga, R.

    1990-07-01

    Deals with ways of improving and standardizing mining regulations in Poland. Shortcomings of existing mining regulations and legal rules are discussed, their main disadvantage being their great multitude and variety. Apart from institutional faults there are also constitutional failures, e.g. exaggerated safety requirements. Another weakness of the existing regulations is the terminology used that is not compatible with standardized mining terminology. Conversion of all regulations, directions and legal acts into standards is recommended as the best means of improvement and the best methods of standarization are suggested. The standards should be issued by only one institution which should be the Higher Mining Office. Establishing Higher and District Mining Offices as the only control structures and a standarized mining law is postulated.

    2002-12-01

    Loss, failure and desertion are those words, which better describe the most frequent difficulties incurred by teenagers, and their relation to the school environment, and indicate, as well, the lack of connection between individual aspirations and school achievements obtained. Despite the likelihood of school difficulties throughout the entire educational career, from the kindergarten to the college, we are able to recognize certain specific "disturbances" which come out during the adolescence, basically relating to the school experiences. School failure, school desertion and school abandonment are, in fact, issues mainly discussed in coincidence with the beginning of the adolescent age and the attending of the high school. The aetiopathogenesis of school discomfort is mostly determined by more than only one factor: psychological, physical, cognitive and environmental aspects, all together, contribute in various ways, to the rise and persisting of the above described problems. Suggesting a univocal characterization of the adolescent with school difficulties, is indeed a hard task, since school failure is not an exclusive feature of only one kind of personality or the expression of only one type of conflict. Once identified the individuals more subject to risk, and the warning signs of actual uneasiness, it is important therefore to intervene timely and in different ways in order to avoid the worsening or the excessive extension of the school difficulties and of their frequent and serious consequences on the teenagers' individual and domestic well-being. Such type of prevention definitely belongs to the Adolescent Medicine, and must be developed on different levels, by involving not only the teenagers, but also their families, the school, and the whole social environment in which the teenagers live and with which they interact.

    2017-06-01

    The Unique Minds Program (Stern, Unique Minds Program, 1999) addresses the socio-emotional needs of children with learning disabilities (LD) and their families. Children and their parents work together in a multiple family group to learn more about LD and themselves as people with the capacity to solve problems in a collaborative way, including problems in family school relationships. This article reports the cultural adaptation of the program for use in Spain and findings from a feasibility study involving three multiple family groups and a total of 15 children and 15 mothers, using a pre-post design. This Spanish adaptation of the program is called "Mentes Únicas". Standardized outcome measures indicated an overall statistically significant decrease in children's self-rated maladjustment and relationship difficulties by the end of the program. Improvements were endorsed by most mothers, although they were not always recognized by the children's teachers. The program had a high level of acceptability: Mothers and children felt safe, understood, and helped throughout the sessions. The efficacy of the adapted intervention for the context of Spain remains to be tested in a more rigorous study. © 2016 Family Process Institute.

    Recent observational evidence suggests that the atmospheric chemical system over China could be more complex than expected, possibly as a result of the rapid increasing anthropogenic emissions. During the CAREBeijing-2007 Experiment in August of 2007, up to 14 ppbv of peroxyacetyl nitrate (PAN, CH3C(O)OONO2) and 4.5 ppbv of glyoxal (CHOCHO) were observed, among the highest levels observed in the world in recent years. Elevated nitrous acid (HNO2) (~1.0 ppbv on average) was also observed in the early afternoon despite of the moderate amount of its precursors, i.e. nitrogen oxides (NOx=NO + NO2). We employ a 1-D photochemical model (REAM) to analyze the observations. The results indicate that reactive aromatics are the dominating source of PAN (55%-75%) and glyoxal (90%), and methylglyoxal is the major precursor of peroxy acetyl radical (50%). Downward transport from boundary layer is found to contribute ~50% of the PAN observed at surface. Photolysis of HNO2 is by far the largest primary OH source (more than 50%) throughout the daytime, and yet the fast formation rate of HNO2 inferred from the observations could not be explained by current known mechanisms. Detailed photochemical analysis is conducted to understand the controlling factors for O3 formation. O3 formation chemistry is strongly affected by aromatics and HNO2. By providing a large primary OH source, HNO2 leads to ~25% enhancement of the average O3 production rate, and aromatics contribute ~40% by serving as a major source of RO2 and HO2 radicals. Due to the large abundance of reactive hydrocarbons, O3 formation is generally NOx limited, although the sensitivity is low that a 50% reduction of NOx could only result in less than 25% reduction of the O3 production rate. Future research targeting HNO2 formation mechanism and emission sources of aromatics is necessary for better understanding the unique photochemical environment in China under significant anthropogenic impacts and the regional pollution

    2016-01-01

    Full Text Available Background: The use of electronic health records (EHRs has continued to increase within healthcare systems in the developed and developing nations. EHRs allow for increased patient safety, grant patients easier access to their medical records, and offer a wealth of data to researchers. However, various bioethical, financial, logistical, and information security considerations must be addressed while transitioning to an EHR system. The need to encrypt private patient information for data sharing is one of the foremost challenges faced by health information technology. Method: We describe the usage of the message digest-5 (MD5 and secure hashing algorithm (SHA as methods for encrypting electronic medical data. In particular, we present an application of the MD5 and SHA-1 algorithms in encrypting a composite message from private patient information. Results: The results show that the composite message can be used to create a unique one-way encrypted ID per patient record that can be used for data sharing. Conclusion: The described software tool can be used to share patient EMRs between practitioners without revealing patients identifiable data.

  19. Mast Cells Produce a Unique Chondroitin Sulfate Epitope.

    The granules of mast cells contain a myriad of mediators that are stored and protected by the sulfated glycosaminoglycan (GAG) chains that decorate proteoglycans. Whereas heparin is the GAG predominantly associated with mast cells, mast cell proteoglycans are also decorated with heparan sulfate and chondroitin sulfate (CS). This study investigated a unique CS structure produced by mast cells that was detected with the antibody clone 2B6 in the absence of chondroitinase ABC digestion. Mast cells in rodent tissue sections were characterized using toluidine blue, Leder stain and the presence of mast cell tryptase. The novel CS epitope was identified in rodent tissue sections and localized to cells that were morphologically similar to cells chemically identified as mast cells. The rodent mast cell-like line RBL-2H3 was also shown to express the novel CS epitope. This epitope co-localized with multiple CS proteoglycans in both rodent tissue and RBL-2H3 cultured cells. These findings suggest that the novel CS epitope that decorates mast cell proteoglycans may play a role in the way these chains are structured in mast cells.

    1989-06-01

    An overview of the distinctive milieu regarding contraceptive methods available in the U.S. considers declining method options, future prospects, reasons for the poor current climate, factors affecting future options, global ramifications, and proposed reforms that may improve the U.S. situation. In the last 3 years, the U.S. lost 3 safe IUDs, and lawsuits now threaten the existence of both spermicides and their associated barrier methods. Meanwhile 2 new IUDs and the cervical cap have been introduced. Future possible methods include Norplant, transdermal patches and a disposable spermicide-releasing diaphragm. The chief reason for loss of contraceptives is the legal system in the U.S. which permits peer juries to evaluate a method's side effects relative to the claimant's former health, rather than actual risk- benefit ratios or medical data. Adverse legal decisions have escalated or eliminated liability insurance. The public is ignorant of the benefits of contraceptives, but misinformed by prominent coverage in the media of preliminary adverse findings. Even the F.D.A., for unstated political reasons, has failed on 2 occasions to approve Depo-Provera, used safely in over 80 countries and approved by the drug agencies of most western nations. Other political factors have cut government funding for contraceptive development steadily for 15 years. Apathy for contraceptive research extends from congress to donor support to numbers of new Ph.D.s entering the field. Ramifications include the highest unplanned pregnancy rate, abortion rate and adolescent pregnancy rate in the developed world in the U.S., and a suspicious stance on the part of developed countries toward U.S. contraceptives, especially those not approved here. Proposed ways of reversing the legal and insurance blocks include reform of tort law and no-fault compensation decided by arbitration.

Subject not only to the same inspections and monitoring as any school, they are also uniquely accountable to their local communities.

    The LHC operations teams are preparing the machine for circulating beams and things are going very smoothly. ALICE and LHCb are getting used to observing particle tracks coming from the LHC beams. During the weekend of 7-8 November, CMS also  saw its first signals from beams dumped just upstream of  the experiment cavern.   Operators in the CMS control room observe the good performance of their detector. Particles are smoothly making their way around the 27 km circumference of the LHC. Last weekend (7-8 November), the first bunches of injection energy protons completed their journey (anti-clockwise) through three octants of the LHC’s circumference and were dumped in a collimator just before entering the CMS cavern. The particles produced by the impact of the protons on the tertiary collimators (used to stop the beam) left their tracks in the calorimeters and the muon chambers of the experiment. The more delicate inner detectors were switched off for protection reasons....

    Boonen, Annemie; Bijnens, Helena

    European higher education institutions will need significant reforms, in order to guarantee their leading role in a globalized knowledge economy. These reforms can be enhanced by improving the way in which traditional universities integrate new technologies both in their educational activities and throughout their strategic and operational processes. The UNIQUe institutional accreditation scheme, analyzed and described in this chapter, intends to support this process of integrating the use of new technologies in higher education. With its specific open approach to quality in e-Learning, UNIQUe emphasizes innovation and creativity in a process that includes self-assessment and constructive dialog with peers and stakeholders involved. UNIQUe intends to use the institutional quality label as a catalyst for continuous improvement and change while setting up collaborative bench learning processes among universities for the adoption and integration of e-Learning.

  9. New ways of insulin delivery.

    Science.gov (United States)

    Heinemann, L

    2010-02-01

    When Exubera (EXU), the first inhaled insulin formulation to make it through the clinical development process, was introduced to the market some years ago it was hoped that this would be the first in a series of novel insulin formulations applied by this route. In addition, it was hoped that inhaled insulin would pave the way for other alternative routes of insulin administration (ARIA), i.e. oral insulin, nasal insulin or transdermal insulin to mention only some of the different attempts that have been studied in the last 90 years. The failure of EXU, i.e. its withdrawal from the market due to insufficient market success, was followed by the cessation of nearly all other attempts to develop inhaled insulin formulations. Currently there is only one company (MannKind) which moves sturdily ahead with their Technosphere insulin. This company has submitted an NDA for their product recently and hopes to bring it to the market by the end of 2010 or early 2011. Even if the product is able to pass the approval hurdles in the USA and Europe, this does not guarantee that it will become a market success. Many diabetologists were sceptical about the need/advantages of inhaled insulin/EXU from the start and the introduction of this product has raised even more scepticism. Reports about 'side effects' (development of lung cancer in patients treated with EXU) of inhaled insulin are also not helpful, even if the causality of the appearance of cancer with this type of insulin therapy is not proven. One of the very negative consequences of stopping EXU are the huge financial losses to Pfizer. The managers in charge in other pharmaceutical companies and also most venture capitalists are reluctant to invest in ARIA nowadays. This in turn means that many of the small companies that try to develop new forms of insulin administration have issues when they try to find a big brother and/or sufficient financial support. Clearly the economic crisis has further aggravated this issue. One can

    Zero energy schools are possible and practical, and architects are leading the way. Imagine a school so inviting that students want to come to school. Now imagine this school housed in a beautiful, light-filled building that produces more energy on an annual basis than it uses. Finally, imagine that the district built this school on the same budget as a conventional school, using typical materials, equipment, and tradespeople. Sound too good to be true Discovery Elementary School in Arlington, Virginia, is living proof that zero energy (ZE) schools are feasible, affordable, and sensible.

    During the summer of 2010, Integrated Ocean Drilling Program (IODP) Expedition 327 conducted coring and observatory installations on the Juan de Fuca Plate to characterize the hydrogeology of ridge-flank ocean crust. Due to the nature of the expedition, a smaller science party than usual was needed. IODP took this opportunity to expand education, outreach, and communication (EOC) activities with a previously untested model. Up to now, the IODP U.S. Implementing Organization had sailed either individual teachers on regular (2-month long) expeditions or groups of teachers and informal educators during short (2-week long) transits (School of Rock workshops). After two shipboard (Expeditions 312 and 321T) and two shore-based (Gulf Coast Repository) programs, we have recognized that sailing a group of educators is a beneficial model for IODP and the participants. What has been unavoidable is that these workshops took place outside typical expedition activities. Expedition 327 provided a unique opportunity to sail a diverse group of outreach officers on a regular expedition with a full range of scientific activities. The group included individuals with a wide variety of skills and backgrounds. US participants included a late-career high school physics teacher, a visualization graduate student, an undergraduate engineering student from an historically black university, and an artist. French participants included two middle and high school earth and life science teachers. This diversity made the group more dynamic but it also posed a challenge. Numerous scientific and technical staff also participated in EOC activity design and leadership, including development of dedicated web sites and blogs. After a seminar on constructivist and inquiry-based methods, we spent the first few weeks investigating earth science concepts so EOC participants could gain a basic understanding of the regional geology and the scientific objectives of the expedition.

    The Qiang are one of the most ancient ethnic groups in China,whose rich culture is an important part of Chinese culture.Beichuan Qiang Autonomous County, Sichuan is a unique Qiang Autonomous County in China,which has an exceptional foundation for transmitting Qiang ethnic culture through school education,no matter whether we speak of its location,talents,policies,or knowl-edge.The transmission of ethnic culture must ad-here to objective laws of cultural development, and,moreoever,the concern for cultural inheritance cannot just be superficial,but should enter and dig deeply into the richness of the content of ethnic culture.This article suggests that in order to trans-mit Qiang culture effectively through school educa-tion in the Qiang areas,the strength of government, school,parents,students and ordinary people should be mobilized.Practical ways to do this include:1 ) The government plays the leading role,and ensures the transmisstion of Qiang culture in school educa-tion;2 ) The schools pay attention to cultural trans-mission and provide space for this work;3 ) The teachers participate actively and provide the“knowledge” needed for transmitting Qiang culture in the schools;4 ) The parents and students give their understanding to these actions, and sweep a-way barriers for transmitting cultural traditions in the schools;5 ) The ordinary people provide support for transmitting Qiang cultural traditions in the schools;and 6 ) The media publicizes this work widely,and provides a voice ” for the transmission of Qiang cultural traditions.

    Canonical Polyadic (also known as Candecomp/Parafac) Decomposition (CPD) of a higher-order tensor is decomposition in a minimal number of rank-1 tensors. In Part I, we gave an overview of existing results concerning uniqueness and presented new, relaxed, conditions that guarantee uniqueness of one factor matrix. In Part II we use these results for establishing overall CPD uniqueness in cases where none of the factor matrices has full column rank. We obtain uniqueness conditions involving Khat...

  1. The Italian Way to Carsharing

    Full Text Available Carsharing (CS is increasing its role worldwide as an alternative transport mode, often more sustainable than private transport with self-owned vehicles. We first focus on the main characteristics of those services and on the impacts they generated, starting from the analysis of  the literature on this topic. CS initiatives are growing everywhere, however numbers are still minor and impacts are still far from a level that can deliver significant aggregate benefits. This paper studies the existing Italian carsharing experiences, trying to understand its strengths, that have allowed its development, but also possible limits and weaknesses. The presence of a national coordination structure (Iniziativa Carsharing - ICS, unique in Europe and created to boost local initiatives providing standardisation and interoperability, surely helped the development of the system. Some initiatives have been successful in terms of membership (in particular Milan, Venice and Turin, but others have been discontinued. Italian users’ characteristics are similar to the ones of users abroad: the majority of users are well educated male, living in small households having one or no cars and using public transport every day. At present, Italian drivers generally still show a scarce propensity to share their cars, considered more as “goods” than as “services”. A case study in Milan, the first and most successful initiative in Italy, shows a significant increase in CS membership after the implementation of a city charging scheme (“Ecopass” at first, then “Area C”. Moving shared cars from garages to “on the street parking” has proved successful too. The usage of the service has changed in time: users have increased (+151% more than runs (+137% – 2006 to 2009, while average length and duration of each run have decreased (-30% and -43% respectively, 2006 to 2010. Milan’s initiative also put s into practice many incentives for users that likely

    2015-03-01

    To present the case of 2 adolescent high school student-athletes who developed postconcussion syndrome with protracted and limiting visual complaints that markedly affected academic, social, and athletic activity for a year after the onset of symptoms. Both had significant improvement soon after a unique intervention was administered. A 14-year-old female soccer and softball player sustained 2 concussions in the same week. She had persistent symptoms for a year that affected her grades and precluded athletic participation. A 15-year-old male football player sustained a concussion during an altercation with 2 other male adolescents. He continued to have symptoms 1 year later, with a marked decrease in academic performance and restriction from athletics. Both adolescents reported blurry vision, photophobia, and associated headache as significant components of the postconcussion syndrome. Concussion, postconcussion syndrome, skull fracture, subdural hematoma, epidural hematoma, second-impact syndrome, and visually sensitive migraine. Both patients were advised to obtain computer gaming glasses to use throughout the day. The female patient was diligent in her use of the glasses, with marked lessening of symptoms. The male patient was less accepting of the glasses but did report lessening of symptoms when using the glasses. We hypothesized that postconcussion syndrome with marked visual complaints would respond to and improve with decreased stimulation of the visual system. This was attempted with the addition of computer gaming glasses. Both adolescent athletes responded well to the filtering of visual stimuli by off-the-shelf computer gaming glasses. Postconcussion syndrome is a persistent condition with a myriad of symptoms. Two young athletes developed postconcussion syndrome with prominent visual symptoms that lasted a year. The addition of computer gaming glasses markedly lessened symptoms in both patients.

The named is the mother of ten thousand things. Ever desireless, one can see the mystery. Ever desiring, one can see the manifestations. These two spring from the same source but differ in name; this appears as darkness. Darkness within darkness. The gate to all mystery."–Lao Tsu (B.C. 2500 The above is an English translation of the first verse of the book "Tao Te Ching" by Lao Tsu. A working meaning of the word "Tao" is "way". The technical jargon "multidisciplinary research" or "interdisciplinary research" are research in many named established areas (i.e. chemistry, physics, sociology, mathematics, statistics, theology, philosophy, political science etc. by an individual or a group of individuals. This type of research has a mysterious common theme that cannot be isolated but is present in the manifestations in various research disciplines. One example of a common theme can be the goal of a new technological innovation. In this article, the problems and solutions of such endeavors are identified by practical analogies of living and nonliving natural phenomena to the above quoted verse by Lao Tsu.

Estudié hermenéutica con los teólogos Gerhard Ebeling y Erns Fuchs en Tübingen, con Philipp Vielhauer en Bonn y con el filósofo Hans-Georg Gadameren Heidelberg durante los años 50. A través de la lectura de Hegel y Marx llegué a aceptar la posición de la dialéctica materialista. Mi autor preferido era Ernst Bloch, quien combina su dialéctica materialista con una interpretación crítica de la religión, especialmente la judeo-cristiana.

    Deaths of initiates occurring in the circumcision initiation schools are preventable. Current studies list dehydration as one of the underlying causes of deaths among traditional male circumcision initiates in the Eastern Cape, a province in South Africa, but ways to prevent dehydration in the initiation schools have not been adequately explored. The goals of this study were to (a) explore the underlying determinants of dehydration among initiates aged from 12 to 18 years in the traditional male circumcision initiation schools and (b) determine knowledge of participants on the actions to be taken to prevent dehydration. The study was conducted at Libode, a rural area falling under Nyandeni municipality. A simple random sampling was used to select three focus group discussions with 36 circumcised boys. A purposive sampling was used to select 10 key informants who were matured and experienced people with knowledge of traditional practices and responsible positions in the communities. The research findings indicate that the practice has been neglected to inexperienced, unskillful, and abusive traditional attendants. The overall themes collated included traditional reasons for water restriction, imbalanced food nutrients given to initiates, poor environmental conditions in the initiation hut, and actions that should be taken to prevent dehydration. This article concludes with discussion and recommendation of ways to prevent dehydration of initiates in the form of a comprehensive circumcision health promotion program.

    Full Text Available One of the most contentious urban education policy issues in the United States today is the expansion of charter schools and its repercussions. Does the expansion of charter schools affect the racial and socioeconomic composition of traditional public schools in the United States? This study provides empirical evidence on this question by relying on a panel design that uses school-level data from two states that have experimented with charter schools for more than 15 years: Ohio and Texas. Using county-level, spatial, and enrollment-based measures of charter exposure, the changes from pre- to post-charter-legislation stages in the student compositions of public schools that do and do not face competition from charters are examined. The results suggest that charter school presence contributes to aggregate-level changes in the share of non-Hispanic White and free-lunch-eligible students in traditional public schools in both states in different ways.

    Full Text Available Education is the means by which society provides for the transmission or advancement of its culture and it is formally done at schools that are the arena of human interaction aimed at producing learning. But some people in that interaction aimed at producing learning cannot achieve as much as the others due to some social or individual factors especially when the society is not homogeneous in terms of culture, language, etc.All cultures do not require the same kinds of knowledge and all may have distinct goals and expectations in education. This study aims at presenting the consensus and conflict in perspectives of students of different ethnic origins on general goals of education and expectations from schools in East and Southeast Turkey. The results will be used to generate a rationale to assume that the failure of students in East and Southeast Turkey where majority of population is ethnically diverse, may be because of the lack of divergent goals and expectations set for school curriculum or that the failure of students is dependent on some other factors except the unique school curriculum unresponsive to cultural or ethnic diversity. For this purpose, the goals of general education (1973, Law number 1739, Item number 2, and school expectations developed by House (1973 were prepared as questionnaire items, piloted, validated and administered to 9373 secondary school students in east and southeast Turkey. The findings of this study were that the students of different ethnic origins value the goals and expectations set for school curriculum in Turkey in significantly different ways.

    2004-11-01

    On June 8, 2004, Venus - the Earth's sister planet - passed in front of the Sun. This rare event - the last one occurred in 1882 - attracted the attention of millions of people all over the world. In a few days' time, on November 5-7, 2004, about 150 educators, media representatives, as well as amateur and professional astronomers will gather in Paris (France) at the international conference "The Venus Transit Experience" to discuss the outcome of the related Venus Transit 2004 (VT-2004) public education programme. This unique project was set up by the European Southern Observatory (ESO), together with the European Association for Astronomy Education (EAAE), the Institut de Mécanique Céleste et de Calcul des Éphémérides (IMCCE) and the Observatoire de Paris in France, as well as the Astronomical Institute of the Academy of Sciences of the Czech Republic. It was also supported by the European Commission in the framework of the European Science and Technology Week, cf. ESO PR 03/04. The VT-2004 programme successfully exposed the broad public to a number of fundamental issues at the crucial interface between society and basic science. It ensured the most comprehensive real-time coverage of the event via an extremely dynamic Central Display that was updated a short intervals. Thanks to the prior establishment of hundreds of mirror sites, the VT-2004 website was easily accessible all through the transit, even though it experienced about 55 million webhits during a period of 8 hours. The VT-2004 programme established a wide international network of individuals (including school teachers and their students, amateur astronomers, interested laypeople, etc.) and educational institutions (astronomical observatories, planetaria, science centres, etc.), as well as 25 National Nodes with their own websites about the Venus Transit in as many local languages. It collected a large number of photos and drawings. It also included an international Video Contest, inviting all
