  1. Consciousness: a unique way of processing information. (United States)

    Marchetti, Giorgio


    In this article, I argue that consciousness is a unique way of processing information, in that: it produces information, rather than purely transmitting it; the information it produces is meaningful for us; the meaning it has is always individuated. This uniqueness allows us to process information on the basis of our personal needs and ever-changing interactions with the environment, and consequently to act autonomously. Three main basic cognitive processes contribute to realize this unique way of information processing: the self, attention and working memory. The self, which is primarily expressed via the central and peripheral nervous systems, maps our body, the environment, and our relations with the environment. It is the primary means by which the complexity inherent to our composite structure is reduced into the "single voice" of a unique individual. It provides a reference system that (albeit evolving) is sufficiently stable to define the variations that will be used as the raw material for the construction of conscious information. Attention allows for the selection of those variations in the state of the self that are most relevant in the given situation. Attention originates and is deployed from a single locus inside our body, which represents the center of the self, around which all our conscious experiences are organized. Whatever is focused by attention appears in our consciousness as possessing a spatial quality defined by this center and the direction toward which attention is focused. In addition, attention determines two other features of conscious experience: periodicity and phenomenal quality. Self and attention are necessary but not sufficient for conscious information to be produced. Complex forms of conscious experiences, such as the various modes of givenness of conscious experience and the stream of consciousness, need a working memory mechanism to assemble the basic pieces of information selected by attention.

  2. Alpbach Summer School - a unique learning experience (United States)

    Kern, K.; Aulinas, J.; Clifford, D.; Krejci, D.; Topham, R.


    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. Epilog: Cajal's unique and legitimated school. (United States)

    Lerma, Juan; De Carlos, Juan A


    Santiago Ramón y Cajal is recognized as the founder of modern neuroscience, his discoveries representing the fundamental pillars of our current understanding of the nervous system. As Cajal's career spanned a critical period in Spanish history, he witnessed strong social demands for progress in culture, education, and science. Indeed, the life of Santiago Ramón y Cajal can be considered to reflect the gradual development of Spanish science from the last third of the 19th century. Cajal promoted a national movement that had important consequences for Spanish science, mainly triggered by the creation of the "Junta para Ampliación de Estudios e Investigaciones Científicas," an instrument he established to enrich scientific research and that was later to bear such abundant fruit. The school generated by Cajal profited from this development, through which all Cajal's disciples received fellowships to train in laboratories across Europe. Unfortunately, the Spanish Civil War disrupted this revitalization of Spanish science and provoked the diaspora of many Spanish scientists. However, a political impulse, mostly following this spirit, was resumed in Spain during the eighties that successfully led to a renaissance in Spanish science.

  4. How business schools lost their way. (United States)

    Bennis, Warren G; O'Toole, James


    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. Practical ways to abate air and water pollution worldwide including a unique way to significantly curb global warming

    Energy Technology Data Exchange (ETDEWEB)

    Snell, J.R.


    This paper points out that in the next 50 years it will largely be the developing countries of the world which will continue to industrialize rapidly and hence pollute the water and air of not only their countries but that this pollution is becoming global (80% of the World's population.) From the author's 25 years of consulting experience in the developing countries, their greatest need is to have available to them low cost, innovative processes for pollution abatement will be neglected and the whole world will suffer immensely. The paper discusses in some detail the type of innovative low cost methods which have successfully been used in the categories of wastewater and solid wastes and names 6 other categories where many others exist. All these innovative methods need to be discovered, listed, and tested for quality and dependability, and then made widely available. Large Environmental Engineering Universities and International Consulting Engineering firms need to be organized to undertake these important tasks. The paper also points out the connection between Global Warming and the Solid waste industry and shows how it can be controlled inexpensively by employing a new, unique, and rapid method of converting municipal refuse into methane and then using that to make electricity. Information given in this paper could lead to a vast reduction in future pollution, with the resulting better global health and at the same time save trillions of dollars.

  9. The Unique and Interactive Effects of Parent and School Bonds on Adolescent Delinquency. (United States)

    Sabatine, Elaina; Lippold, Melissa; Kainz, Kirsten


    Parent and school bonds are protective against delinquency. This study used longitudinal data and multilevel Poisson regression models (MLM) to examine unique and interactive associations of parent and school bonds on youth delinquency in a sample of rural adolescents ( n = 945; 84% White). We investigated whether youth sex or transitioning to a new middle school moderated the linkages between parent and school bonds and later delinquency. Results indicated reduced delinquency was associated with positive parent and school relationships. Parent and school bonds interacted such that linkages between parent bonding and youth delinquency were stronger when youth also had high school bonding - suggesting an additive effect. However, interactive effects were only found when youth remained in the same school and became nonsignificant if they transitioned to a new school. Findings support prior evidence that parent and school bonds - and their interaction - play a unique role in reducing delinquency.

  14. University Involvement with Charter Schools: Unique Opportunities for Service and Support

    Directory of Open Access Journals (Sweden)

    Dr. Julie Hentges


    Full Text Available Charter schools are a controversial, but vibrant, component of the current educational landscape, now serving over 3.1 million students in approximately 6900 schools across the United States.  A unique aspect of this movement has been the establishment of alternative authorizers, and specifically universities, to approve and provide oversight to these public schools.  Campus leaders and policy makers must consider numerous variables regarding a university’s involvement with charter schools.  What are the implications of school choice on university policies and practices? Should universities be “authorizers”, granting charters to schools in direct competition with the traditional public school system? Can universities provide the required “oversight” mandated by the charter school laws, as well as providing “support” for the schools? What opportunities for partnerships and practicum experiences exist?  The article provides an overview of issues that arise with public charter schools authorized by universities.  With 18 years of experiences as a public university on the forefront of enabling charter legislation and the “sponsorship” of inner-city public charter schools, the authors provide a historical perspective of the role of universities within the school choice movement, including oversight roles and supportive programs within the unique and growing phenomenon of school choice.

  1. Unique Contributors to the Curriculum: From Research to Practice for Speech-Language Pathologists in Schools. (United States)

    Powell, Rachel K


    This lead article of the Clinical Forum focuses on the research that supports why speech-language pathologists (SLPs) are an integral part of the overarching curriculum for all students in schools. Focus on education has shifted to student performance in our global world, specifically in college and career readiness standards. This article reviews recommendations on best practice from the American Speech-Language-Hearing Association on SLPs' roles in schools, as well as data on school-based services. Implementation of these practices as it is applicable to school initiatives will be explored. Methods of interventions available in schools, from general education to special education, will be discussed based on national guidelines for a Response to Intervention and Multi-Tiered System of Support. Research regarding teacher knowledge of the linguistic principles of reading instruction will be explored, as well as correlation between teacher knowledge and student performance. The implications for how SLPs as the linguistic experts offer unique roles in curriculum and the evidence available to support this role will be explored. Implications for future research needs will be discussed. The demands of a highly rigorous curriculum allow SLPs a unique opportunity to apply their knowledge in linguistic principles to increase student performance and achievement. With the increased focus on student achievement, growth outcome measures, and value-added incentives, it is critical that SLPs become contributors to the curriculum for all students and that data to support this role are gathered through focused research initiatives.

  2. Low back pain at school: unique risk deriving from unsatisfactory grade in maths and school-type recommendation. (United States)

    Erne, Cordula; Elfering, Achim


    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.

  13. A New Way of Using the Interactive Whiteboard in a High School Physics Classroom: A Case Study (United States)

    Gregorcic, Bor; Etkina, Eugenia; Planinsic, Gorazd


    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.

  14. Unique contributions of dynamic versus global measures of parent-child interaction quality in predicting school adjustment. (United States)

    Bardack, Sarah; Herbers, Janette E; Obradović, Jelena


    This study investigates the unique contribution of microsocial and global measures of parent-child positive coregulation (PCR) in predicting children's behavioral and social adjustment in school. Using a community sample of 102 children, ages 4-6, and their parents, we conducted nested path analytic models to identify the unique effects of 2 measures of PCR on school outcomes. Microsocial PCR independently predicted fewer externalizing and inattention/impulsive behaviors in school. Global PCR did not uniquely relate to children's behavioral and social adjustment outcomes. Household socioeconomic status was related to both microsocial and global measures of PCR, but not directly associated with school outcomes. Findings illustrate the importance of using dynamic measures of PCR based on microsocial coding to further understand how the quality of parent-child interaction is related to children's self-regulatory and social development during school transition.

  1. Podcasting as a novel way to communicate with medical school applicants. (United States)

    Ferguson, Benjamin D; Bister, Mary K; Krapec, Joni N


    Podcasting in medical education is becoming more widely used and may be a useful tool for communicating with applicants to medical school. Given recent trends in the popularity of podcasting and mobile media, we created a podcast to communicate more effectively with applicants to our medical school as well as with the broader premedical community. The purpose of this study was to characterize the listening habits and motivations of our audience and compare the podcast's benefits to those of other resources. We additionally sought to understand patterns by which our podcast was consumed by a premedical audience. We surveyed medical school applicants who interviewed at the University of Chicago Pritzker School of Medicine for matriculation in 2013. Forty-one percent of those surveyed had listened to the podcast prior to their interview. Only 12 % of listeners accessed the podcast using a mobile device. Ninety-two percent of listeners felt that it faithfully represented the medical school, and 81 % felt that listening would encourage the decision to matriculate. A majority of listeners responded that the podcast was more helpful than other traditional resources. This is the first use of podcasting in medical school admissions and represents a novel way to communicate with prospective students. Our findings demonstrate that podcasting can be an effective tool for communicating with applicants to medical school and highlight its usefulness in recruitment. This method of communication could be adopted by other medical schools to enhance the ways in which they inform their own prospective medical students.

  3. Plutonium uniqueness

    International Nuclear Information System (INIS)

    Silver, G.L.


    A standard is suggested against which the putative uniqueness of plutonium may be tested. It is common folklore that plutonium is unique among the chemical elements because its four common oxidation states can coexist in the same solution. Whether this putative uniqueness appears only during transit to equilibrium, or only at equilibrium, or all of the time, is not generally made clear. But while the folklore may contain some truth, it cannot be put to test until some measure of 'uniqueness' is agreed upon so that quantitative comparisons are possible. One way of measuring uniqueness is as the magnitude of the product of the mole fractions of the element at equilibrium. A 'coexistence index' is defined and discussed. (author)

    Energy Technology Data Exchange (ETDEWEB)


    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.

  6. Acoustic and social design of schools-ways to improve the school listening environment (United States)

    Hagen, Mechthild


    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.

  9. The Transition Year: A Unique Programme in Irish Education Bridging The Gap Between School and The Workplace

    Directory of Open Access Journals (Sweden)

    Joseph A. MOYNIHAN


    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.

  10. Public Politics and Democratic Administration: the way school board works with the Municipal Secretary of Education

    Directory of Open Access Journals (Sweden)

    Celso Conti


    Full Text Available The great depth of changes in the capitalism system beginning in the middle of the twentieth century has produced a total new way of life, which encloses from social behavior patterns to the relationship between capital, employment and the State. International organisms have been created to organize the changing process in the Nations’ agenda around the world, including the educational area that begins to be understood as priority justifying the needs of a new social pact, which implies the participation of the whole society. In Brazil, the municipal, state and federal laws sanction the principle of “democratic administration”. What we need to verify, though, is how this principle has been put in practice. Hence, the text intends to analyze the school board performance within the education system of São Carlos/SP, identifying the participation possibilities of the community inside the school. For that, we used the statements given by the municipal school counselors, and, as a result we identified two important obstacles regarding the democratic inner workings of the school board: one related to parity and power sharing; and the other regarding the representation.

    Full Text Available Personal financial education is primordial in society, as it influences directly the economic decisions of individuals. This way, the present survey, based on a project that developed and implemented a financial education course for young people, aims to measure the financial literacy level of the students, before and after the course. The sample comprised 302 elementary school students from public schools in Santa Maria, aged between 11 and 17. The results show that the students had a low financial knowledge, which improved after the course, and the variables “math grades”, “parental education” and “total household monthly incomes” are significant to the financial literacy level of students.

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

    Directory of Open Access Journals (Sweden)

    Flor Ángela Gutiérrez Castro


    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.

  18. Managerialism and performativity: is it the only way to quality public school?

    Directory of Open Access Journals (Sweden)

    Mauricio de Sousa


    Full Text Available This article presents a research on editorials of the two main printed newspapers with the largest circulation and reach in Brazil: “Folha de São Paulo” and “O Estado de São Paulo”. The editorials were published between 2007 and 2016, and their analysis refer to the relationship between Basic Education Development Index (IDEB and school management. The concepts of performativity and managerialism developed by Stephen Ball were used to analyze the educational reforms that took place in Europe in the last decades, which have resulted in the introduction of market values and the definition of quality, which is achieved through competition, efficiency, performance and professional accountability. As a consequence of these reforms, we have disqualified public service management, especially in education. Using the analysis of the discourses as a methodology, 30 editorials were studied, and we found that, like in Europe, Brazilian public education is of poor quality, since the students performance in national and international external evaluations is very low. Thus, it is considered that the way to improve the quality of public education would be to reform school management in an efficient and competitive manner. Consequently, the editorials analyzed stated that quality education is what qualifies students for the job market and not for a social transformation, in a perspective of social quality education, valuing the integral formation of the human being.

  20. The Utah Nuclear Engineering Program and DevonWay are Developing One and Unique Approach to PLiM for Securing the Nation's Nuclear Future

    International Nuclear Information System (INIS)

    Jevremovic, Tatjana; Choe, Dongok; Yang, Haori; White, Sally; Kelly, Mike


    The safety culture involving a comprehensive training of the employed engineers at the power plant facilities is neither a simple nor a straightforward task. With aging management and operators, impact of the Fukushima nuclear event, unforeseen and timely unpredictable effects of nuclear memories (Three Mile Island, Chernobyl, Second World War) as evoked every time we have worldwide challenges or discussions of where the nuclear technology will/would further develop, we face a fearful question - is our educational and training approach the right one; is it going to assure continuous and secured practices in providing safe operation of our nuclear power plants?... We at the University of Utah with our just recently revitalized Nuclear Engineering Program, find that the root of securing the safety culture and providing its sustainability in our existing and future nuclear power plants, lies in very early educational practices. We believe that every program in nuclear engineering education shall include training in nuclear safety. That training shall certainly include industrial based practices and involve experts from the companies that develop and contribute to nuclear power safety to add to class practices at the University teaching settings. Working with DevonWay, a leading company in developing software to improve the safety cultures at nuclear power plants in the country, we have implemented the 'Track and Trace' software into our nuclear engineering program, emphasizing high quality training of our undergraduate and graduate students, and promoting a higher level safety culture practices at our nuclear engineering facilities.

  4. Instant messaging: The way to improve access for young people to their school nurse. (United States)

    Schuller, Lynne; Thaker, Kelly


    Children and young people require ease of access to their school nurse. Alongside this, school nurses are charged with the need to work smarter, being cost-effective and timely in response. School nursing teams across the country provide access through text messaging, however, there is presently no access provided to young people to have a consultation as a web-based chat facility. Using digital media, Doncaster school nurses have worked closely with young people to redesign and launch a totally interactive web- based clinic facility. This allows for improved access, reduction in travel costs and consultations to take place outside of the traditional times for accessing school nurses. This paper discusses a pilot project around the establishment of an e-clinic connecting young people and school nurses. It outlines the journey towards providing this innovative service in an attempt to provide cost-effective, timely services while reducing the barriers for service users.

  12. Is scratch-cooking a cost-effective way to prepare healthy school meals with US Department of Agriculture foods? (United States)

    Woodward-Lopez, Gail; Kao, Janice; Kiesel, Kristin; Lewis Miller, Markell; Boyle, Maria; Drago-Ferguson, Soledad; Braff-Guajardo, Ellen; Crawford, Patricia


    Despite the resurgence of interest in scratch-cooking as a way to increase the quality and appeal of school meals, many school districts are concerned about the cost implications of switching to scratch-cooking. US Department of Agriculture (USDA) Foods are the single largest source of ingredients for school meals, and about half of USDA Foods are diverted for processing before being sent to the school district. We aimed to determine whether school lunch entrées made in a district from basic or raw USDA Foods ingredients can be healthier and less expensive to prepare than those sent to external processors. This cross-sectional study examined the relationship between the extent of scratch-cooking and the nutritional content and cost to prepare entrées. Information was gathered by interview with school foodservice personnel and from school foodservice records from a convenience sample of 10 school districts in California that employed varying degrees of scratch-cooking and is diverse in terms of geographic location and the sociodemographics of the student body. The sample included all elementary school lunch entrées that contain USDA Foods offered during October 2010 for a total sample of 146 entrées. Ordinary least squares regressions were used to test for statistically significant differences in cost and nutrient content of entrées according to the level of scratch-cooking. There was no significant relationship between total costs and level of scratch-cooking. Entrées with the highest scratch-cooking scores had significantly lower food costs, higher labor costs, and not significantly different total costs compared with entrées with no scratch-cooking. Nutrient content was not consistently associated with scratch-cooking, but scratch-cooked entrées did include a larger variety of non-fast-food-type entrées. The findings suggest that scratch-cooking can be a cost-effective way to expand the variety of healthy school lunches prepared with USDA Foods

  13. Beyond corporate-style downsizing: a better way for medical schools to succeed in a changing world. (United States)

    Bland, C J


    There is a critical need for medical schools and universities to consider strategies beyond corporate-style downsizing to address revenue needs and reposition their organizations. The author presents considerable evidence and three reasons to reject downsizing as a way to facilitate long-term organizational success. Instead, she recommends that institutions use a comprehensive approach to individual and organizational development to assure a flexible, enduring organization. Specifically, medical schools and universities should take an institution-wide perspective and approach to continually training, retraining, or reassigning faculty and should continually adapt their organizational structures and procedures as necessary to achieve changing institutional goals. The result will be the retention of able and dedicated faculty, who will be crucial in helping their schools continue to be successful while adapting to a changing world.

    In the wide range of PLS activities, one on semiconductors was realized with high-school 4th- and 5th-year students. After an introduction on semiconductor and electromagnetic radiation concepts, students assembled circuits, observed photoresistor and LED behavior and compared experimental and theoretical results. We especially paid attention to energy conversions and devices applications. An important point of the project is that it can be easily realized in our schools because low-cost devices are used. Moreover, discussing experimental results, it is possible to correct or complete students phenomena interpretation.

In this context, it addresses the implementation of a system harnessing rainwater for non-potable purposes in a school unit. This article aimed to evaluate the results obtained from the use of tanks to capture and use of rainwater in a state school of Paraná, in the city of Marechal Cândido Rondon. It is a descriptive exploratory research, qualitative and quantitative approach. Based on data from historical series water consumption of the College Eron Domingues, a relationship between the consumption of water and the monthly rainfall for the period was established. The results confirmed the efficiency of the capture of rain water system, reducing the consumption of treated water supplied by the Water and Sewage Company, up 57.2%. Thus, while stimulating in students an awareness focused on sustainability, inclusion of knowledge and environmental practices at school, comprise the prospect of a multiplier effect on society.

  9. Organ transplant education: the way to form altruistic behaviors among secondary school students toward organ donation. (United States)

    Milaniak, I; Przybylowski, P; Wierzbicki, K; Sadowski, J


    Organ shortage for transplantation is a crucial problem all over the world. Educational intervention may appeal to young people's altruism, increasing organ donation and decreasing the opposition. This study assessed the influence of an educational program, including organ donation and transplantation, to forming students' altruistic behaviors. A total 680 students of 25 secondary schools were asked about their attitudes, intentions, and knowledge about organ donation and transplantation from September 2008 to June 2009 during a 45-minute lesson. In this study, altruistic attitudes were measured through questions about the expression of will to give organs away after death; to give one kidney to relatives; to use the bone marrow from a foreign person; and to sign a donor card. Attitudes were assessed by questions about conversations with relatives, an evaluation of the educational project. More than 1500 donor card were distributed and more than 90% of students wanted to sign them; 73.6% agreed to sign a donor card with the ID card. Before the project, only 8% of students had a signed donor card. Almost everybody is ready to agree to give their organs after death (80.6% male; 92.2% female), or to relatives (100% male; 90.38% female), or bone marrow (80% male; 55.7% female). The students talked to their family, informing them about their decision (36.9% male; 45.9% female). The proposed educational project successfully encouraged teenagers to make well-considered choices with regard to organ donation and created altruistic behaviors.

  12. Coteaching with senior students – a way to refine teachers' PCK for teaching chemical bonding in upper secondary school (United States)

    Schultze, Felix; Nilsson, Pernilla


    During the last decade there has been on-going discussions about students' declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers' and students' different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students' frames of references. The teachers' PCK was refined which in turn lead to improved teaching strategies.

  14. Educational outcomes of the Harvard Medical School-Cambridge integrated clerkship: a way forward for medical education. (United States)

    Hirsh, David; Gaufberg, Elizabeth; Ogur, Barbara; Cohen, Pieter; Krupat, Edward; Cox, Malcolm; Pelletier, Stephen; Bor, David


    The authors report data from the Harvard Medical School-Cambridge Integrated Clerkship (CIC), a model of medical education in which students' entire third year consists of a longitudinal, integrated curriculum. The authors compare the knowledge, skills, and attitudes of students completing the CIC with those of students completing traditional third-year clerkships. The authors compared 27 students completing the first three years of the CIC (2004-2007) with 45 students completing clerkships at other Harvard teaching hospitals during the same period. At baseline, no significant between-group differences existed (Medical College Admission Test and Step 1 scores, second-year objective structured clinical examination [OSCE] performance, attitudes toward patient-centered care, and plans for future practice) in any year. The authors compared students' National Board of Medical Examiners Subject and Step 2 Clinical Knowledge scores, OSCE performance, perceptions of the learning environment, and attitudes toward patient-centeredness. CIC students performed as well as or better than their traditionally trained peers on measures of content knowledge and clinical skills. CIC students expressed higher satisfaction with the learning environment, more confidence in dealing with numerous domains of patient care, and a stronger sense of patient-centeredness. CIC students are at least as well as and in several ways better prepared than their peers. CIC students also demonstrate richer perspectives on the course of illness, more insight into social determinants of illness and recovery, and increased commitment to patients. These data suggest that longitudinal integrated clerkships offer students important intellectual, professional, and personal benefits.

  1. [Infant moods and the chronicity of depressive symptoms: the co-creation of unique ways of being together for good or ill. Paper 1: The normal process of development and the formation of moods]. (United States)

    Tronick, Edward Z


    The ontogenesis of moods and the process that establishes them is addressed. Moods arise out of normal developmental processes at both a macro- and micro-developmental level. Moods are part of normal development as well as a component of pathological processes and they are a ubiquitous presence that gives meaning to experience in infant and adult during daily life and therapy. In this first part of a two-part paper I will address the normal development of moods; in the second part I will to address issues related to psychopathology and therapy, especially depression and the intergenerational transfer of mood. I argue that moods are dyadic phenomena--something that develops out of the chronic co-creative interactions of two individuals--rather than solely being an intrapsychic process. I will also argue, especially when one considers the development of moods in infants, that moods make sense of the world as components of states of consciousness that give unique meaning to the individual's engagement with the world and further that moods function to bring the past into the present.

  2. Exploring new ways of media construction of citizenship in schools: from «Antigone» to transmedia storytelling

    Directory of Open Access Journals (Sweden)

    Gonzalo JOVER


    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.

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

  13. The partnership between the Brazilian School Feeding Program and family farming: a way for reducing ultra-processed foods in school meals. (United States)

    Teo, Carla Rosane Paz Arruda


    To evaluate the profile of food acquisition in the National School Feeding Program according to the extent and purpose of food processing in three municipalities of southern Brazil during the implementation period of Law 11.947/2009. Descriptive cross-sectional study. Data for 2008-2010 involved quantities, prices and types of suppliers for food items purchased. In total, 1529 purchases were analysed. The items were classified into the following groups: G1 (unprocessed/minimally processed), G2 (culinary ingredients), G3 (processed), G4 (ultra-processed). Quantities of purchased foods were converted into energy and average prices ($US/4184 kJ (1000 kcal)) were calculated. The proportion of each food group in total purchases was expressed as both a percentage of total energy and a percentage of total expenditure. Data analysis was carried out in Stata version 12.1. Three municipalities in southern Brazil. Relative contribution to total energy purchased was high for G1 (49·8 %; G2, 23·8 %; G3, 4·5 %; G4, 21·8 %). Among acquisitions from family farming, G1 represented 51·3 % of the total energy purchased; G2, 9·9 %; G3, 19·7 %; G4, 19·0 %. Total cost was as follows: G1, 61·6 %; G2, 3·9 %; G3, 18·5 %; G4, 16·0 %. Prices for food products from family farms were consistently higher. Average price from family farms was 1·3; from conventional suppliers, 0·9. The implementation of Law 11.947/2009 produced a positive effect on the regional profile of food purchases for the School Feeding Program. However, there is still considerable potential to promote health by strengthening relationships between family farming and school feeding.

    The attenuation of charmonium formation in relativistic collisions of heavy ions is considered to be the most promising signature of quarkgluon plasma formation. The promise remains suspect because very little experimental data exist which can convincingly refute alternate explanations of the observed suppression. An experimental measurement of charmonium formation in antiproton annihilation with nuclear protons is proposed to answer some of the questions posed by the alternate explanations. (orig.)

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

  3. Is Life Unique? (United States)

    Abel, David L.


    Is life physicochemically unique? No. Is life unique? Yes. Life manifests innumerable formalisms that cannot be generated or explained by physicodynamics alone. Life pursues thousands of biofunctional goals, not the least of which is staying alive. Neither physicodynamics, nor evolution, pursue goals. Life is largely directed by linear digital programming and by the Prescriptive Information (PI) instantiated particularly into physicodynamically indeterminate nucleotide sequencing. Epigenomic controls only compound the sophistication of these formalisms. Life employs representationalism through the use of symbol systems. Life manifests autonomy, homeostasis far from equilibrium in the harshest of environments, positive and negative feedback mechanisms, prevention and correction of its own errors, and organization of its components into Sustained Functional Systems (SFS). Chance and necessity—heat agitation and the cause-and-effect determinism of nature’s orderliness—cannot spawn formalisms such as mathematics, language, symbol systems, coding, decoding, logic, organization (not to be confused with mere self-ordering), integration of circuits, computational success, and the pursuit of functionality. All of these characteristics of life are formal, not physical. PMID:25382119

    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.

  14. Let Me Put It Another Way: Methodological Considerations on the Use of Participatory Photography Based on an Experiment with Teenagers in Secondary Schools

    Directory of Open Access Journals (Sweden)

    Jose M. Coronel


    Full Text Available This article reflects on the use of participant photography as a methodological component of a qualitative research study into student intercultural relations in four secondary schools in Spain. 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.

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 space-times ceases to exist in self-gravitating non-linear field theories. This text aims to review some of the recent developments and to discuss them in the light of the uniqueness theorem for the Einstein-Maxwell system.

  1. Fingerprinting the Milky Way (United States)


    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

  2. The liberal illusion of uniqueness. (United States)

    Stern, Chadly; West, Tessa V; Schmitt, Peter G


    In two studies, we demonstrated that liberals underestimate their similarity to other liberals (i.e., display truly false uniqueness), whereas moderates and conservatives overestimate their similarity to other moderates and conservatives (i.e., display truly false consensus; Studies 1 and 2). We further demonstrated that a fundamental difference between liberals and conservatives in the motivation to feel unique explains this ideological distinction in the accuracy of estimating similarity (Study 2). Implications of the accuracy of consensus estimates for mobilizing liberal and conservative political movements are discussed.

  3. A comparison of students who chose a traditional or a problem-based learning curriculum after failing year 2 in the traditional curriculum: a unique case study at the Nelson R. Mandela School of Medicine. (United States)

    McLean, Michelle


    To canvas perceptions and experiences of students who had failed Year 2 of a traditional medical program and who chose to remain in the conventional program (n = 6) or had swapped to Curriculum 2001 (C2001), a problem-based learning (PBL) curriculum (n = 14). A year after their decision regarding curriculum choice, students were canvassed (largely open-ended survey) about this decision and about their perceptions of their curricular experiences. C2001 students were positive about their PBL experiences. Overwhelmingly, their decision to swap streams had been a good one. They identified PBL features as supporting their learning. Repeating traditional curriculum students were, however, more circumspect in their opinions. C2001 students had clearly embraced PBL. They were now medical students, largely because of PBL activities underpinned by a sound educational philosophy. This unique case study has provided additional evidence that PBL students are generally more content with their studies than their conventional curriculum counterparts.

  6. Kosovo case: A unique arbitrariness

    Directory of Open Access Journals (Sweden)

    Nakarada Radmila


    Full Text Available The end of Cold war, contrary to expectations has brought new conflicts and forms of violence, new divisions and new relativizations of the international legal order. Taking as an example the endeavors to resolve the Kosovo conflict, the author attempts to indicate the broader implications of the international efforts to constitute an independent state on part of the territory of an existing sovereign state. The arguments used to justify the redefinition of the borders of the Serbian state without its consent, the moral, democratic, peace arguments, are reviewed. Particular attention is paid to the argument that Kosovo is a unique case and therefore unique rules should be applied. The author seeks to understand the deeper significance of these efforts, concluding that dismantling the present international legal order is not only a potential danger but a possible aim.

  7. Uniqueness theorems in linear elasticity

    CERN Document Server

    Knops, Robin John


    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...

    Bergh, Ingunn H; Bjelland, Mona; Grydeland, May; Lien, Nanna; Andersen, Lene F; Klepp, Knut-Inge; Anderssen, Sigmund A; Ommundsen, Yngvar


    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. 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. 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 determinants were observed among those receiving a high

    The Way of the Sign is a book about extraction, about reducing methods of inquiry to the bare bones. It guides students through 10 schools of theory and criticism. The focus is on ‘asking’ each theory to give its best in the simplest way, by making us see what is at stake and how we might respond...... to it. In simple Socratic dialogues, Elias invents scenarios: ‘What is happening?’ Deconstruction asks. And we answer with it: ‘We are buying a mythology.’ ‘How does it make us feel?’ ‘Dumb.’ ‘What is happening?’ Marxism asks. And we answer with it: ‘The rich cheat us.’ ‘How does it make us feel...

    That there is no Milton Friedman today is not a mystery; the mystery is how Milton Friedman could have been. The facts of Friedman’s biography make him unique among twentieth-century public figures. He had extensive knowledge and expertise in mathematics and statistics. Yet he became a critic of ‘formal’ theory, exemplified by mathematical economics, that failed to engage with real-world facts and data, and of econometric modeling that presumed more knowledge of economic structure than Friedm...

  15. Unique Features of Halophilic Proteins. (United States)

    Arakawa, Tsutomu; Yamaguchi, Rui; Tokunaga, Hiroko; Tokunaga, Masao


    Proteins from moderate and extreme halophiles have unique characteristics. They are highly acidic and hydrophilic, similar to intrinsically disordered proteins. These characteristics make the halophilic proteins soluble in water and fold reversibly. In addition to reversible folding, the rate of refolding of halophilic proteins from denatured structure is generally slow, often taking several days, for example, for extremely halophilic proteins. This slow folding rate makes the halophilic proteins a novel model system for folding mechanism analysis. High solubility and reversible folding also make the halophilic proteins excellent fusion partners for soluble expression of recombinant proteins.

    The Atoms for Peace program was a unique gesture of sharing on the part of the leading industrialized nation, and has very few parallels in modern history. The author says one of the major advantages of the program for developing nations was the much needed stimulation of their indigenous science and technology efforts and the awakening of their governments to the multifaceted benefits of atomic energy. The author discusses how the program benefited Pakistan in the production of electrical energy and in the application of nuclear techniques in the fields of agriculture and medicine, which help to alleviate hunger and combat disease

    Barash, Isaac


    In this article, I briefly recount the historical events in my native country that led me to become a plant pathologist. I started as a field pathologist specializing in fungal diseases of legumes, moved to biochemical research on virulence factors, and then on to molecular plant-microbe interactions. I describe the impact my graduate studies at the University of California (UC)-Davis had on my career. My life's work and teaching can be said to reflect the development in plant pathology during the past 40 years. I have included a concise review of the development of plant pathology in Israel and the ways it is funded. Dealing with administrative duties while conducting research has contributed to my belief in the importance of multidisciplinary approaches and of preserving the applied approach in the teaching of plant pathology.

  19. Unique features of space reactors

    International Nuclear Information System (INIS)

    Buden, D.


    This paper reports on space reactors that 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

    Mavis Maria Raborife


    Full Text Available As the shift towards inclusive education intensifies, the need for school to work collaboratively with families becomes necessaryfor the sake of maximizing students’ academic success. However, in certain communities such effort is often undermined byvarious factors which interact directly and/or indirectly with both institutions – school and family. Schools located in informalsettlements of South Africa are not unique to this situation. This paper presents the perspectives of parents, educators andschool management teams about barriers which inhibit collaboration between the school and families. Interviews conducted ingroups and with individual participants were followed as data collection strategies. Findings revealed factors falling under threecategories, namely: community, schools and family factors. These factors interact with each other in a dynamic way to createchallenges to undermine school-family collaboration. The findings of this study could guide school efforts for promotingmeaningful and long-lasting relationships with families.

  4. The Fourth Way in Finland

    Directory of Open Access Journals (Sweden)

    Vesa Iitti


    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. 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. It is a unique combination of cosmology, psychology, theory of evolution, and overall theory and practise aiming to help individ­uals in their efforts towards what is called ‘self-remembering’.

    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.

  7. ROSAT Discovers Unique, Distant Cluster of Galaxies (United States)


    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.

  13. Unique Fock quantization of scalar cosmological perturbations (United States)

    Fernández-Méndez, Mikel; Mena Marugán, Guillermo A.; Olmedo, Javier; Velhinho, José M.


    We investigate the ambiguities in the Fock quantization of the scalar perturbations of a Friedmann-Lemaître-Robertson-Walker model with a massive scalar field as matter content. We consider the case of compact spatial sections (thus avoiding infrared divergences), with the topology of a three-sphere. After expanding the perturbations in series of eigenfunctions of the Laplace-Beltrami operator, the Hamiltonian of the system is written up to quadratic order in them. We fix the gauge of the local degrees of freedom in two different ways, reaching in both cases the same qualitative results. A canonical transformation, which includes the scaling of the matter-field perturbations by the scale factor of the geometry, is performed in order to arrive at a convenient formulation of the system. We then study the quantization of these perturbations in the classical background determined by the homogeneous variables. Based on previous work, we introduce a Fock representation for the perturbations in which: (a) the complex structure is invariant under the isometries of the spatial sections and (b) the field dynamics is implemented as a unitary operator. These two properties select not only a unique unitary equivalence class of representations, but also a preferred field description, picking up a canonical pair of field variables among all those that can be obtained by means of a time-dependent scaling of the matter field (completed into a linear canonical transformation). Finally, we present an equivalent quantization constructed in terms of gauge-invariant quantities. We prove that this quantization can be attained by a mode-by-mode time-dependent linear canonical transformation which admits a unitary implementation, so that it is also uniquely determined.

    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. 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. Time spent on TV/DVD (week p = 0.001, weekend p = 0.03) and computer/game-use (week p = 0.004, weekend p effects of the intervention were found for boys, but moderation effects were found for WS (week days: TV/DVD, p = 0.03 and computer/games, p = 0.02). There were no moderating effects of parental education for neither boys nor girls with respect to intake of SSB, time used for watching TV/DVD and computer/game-use. Parental awareness of the intervention was significantly higher among the parents of girls, while the parents of boys were more satisfied with the fact sheets. 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

    Grochow, Joshua A.; Tucker-Foltz, Jamie


    Covering spaces of graphs have long been useful for studying expanders (as "graph lifts") and unique games (as the "label-extended graph"). In this paper we advocate for the thesis that there is a much deeper relationship between computational topology and the Unique Games Conjecture. Our starting point is Linial's 2005 observation that the only known problems whose inapproximability is equivalent to the Unique Games Conjecture - Unique Games and Max-2Lin - are instances of Maximum Section of...

  8. The Milky Way Skeleton (United States)

    Zucker, Catherine; Battersby, Cara; Goodman, Alyssa A.


    Recently, Goodman et al. (2014) argued that a very long, very thin infrared dark cloud 'Nessie' lies directly in the Galactic mid-plane and runs along the Scutum-Centaurus arm in position-position-velocity space as traced by low density CO and high density NH3 gas. Nessie was presented as the first 'bone' of the Milky Way, an extraordinarily long, thin, high contrast filament that can be used to map our galaxy's 'skeleton.' We present the first evidence of additional 'bones' in the Milky Way Galaxy, arguing that Nessie is not a curiosity but one of many filaments that could potentially trace galactic structure. Our ten bone candidates are all long, filamentary, mid-infrared extinction features which lie parallel to, and no more than twenty parsecs from, the physical Galactic mid-plane. We use CO, N2H+, and NH3 radial velocity data to establish the location of the candidates in position-velocity space. Of the ten filaments, three candidates have a projected aspect ratio of >50:1 and run along, or extremely close to, the Scutum-Centaurus arm in position-velocity space. Evidence suggests that these three candidates are Nessie-like features which mark the location of the spiral arms in both physical space and position-velocity space. Other candidates could be spurs, feathers, or interarm clouds associated with the Milky Way's galactic structure. As molecular spectral-line and extinction maps cover more of the sky at increasing resolution and sensitivity, we hope to find more bones in future studies, to ultimately create a global-fit to the Galaxy's spiral arms by piecing together individual skeletal features. This work is supported in part by the NSF REU and DOD ASSURE programs under NSF grant no. 1262851 and by the Smithsonian Institution.

    IAU Symposium 106, held at the Kapteyn Institute in Groningen, presents an overview of all major aspects of galactic astronomy. The vast subject is covered in 20 authoritative review papers and 22 invited papers, each with discussion, plus 81 shorter contributions. The book opens with 4 reviews by historians of science, outlining the history of galactic research. Part 2 deals with (i) galactic rotation, (ii) the large-scale distributions of matter, of both old and young stellar populations, and of the atomic, molecular and high-energy components of the interstellar medium, (iii) small-scale structure in the gas, (iv) the galactic nucleus, (v) the high-velocity clouds. Part 3 discusses the dynamics of the local group of Galaxies and of the Milky Way-Magellanic clouds system, the dynamical and chemical evolution of the Galaxy and of its disk and halo components and the formation of the Galaxy. The controversial subject of spiral structure and star formation is analyzed in several extensive reviews and lively discussions, featuring both observational and theoretical developments. Results of extragalactic research are blended with studies of our Galaxy throughout the book, and there is a separate comparison between Andromeda and Milky Way Galaxies. The Symposium featured the first maps produced by IRAS, and results from most major telescopes in a variety of wavebands. Many review papers present material not published elsewhere. The book closes with a lecture on life in the Galaxy and with an imaginative symposium summary. (orig.)

  10. A Phenomenographic Investigation of the Ways Engineering Students Experience Innovation (United States)

    Fila, Nicholas David

    Innovation has become an important phenomenon in engineering and engineering education. By developing novel, feasible, viable, and valued solutions to complex technical and human problems, engineers support the economic competitiveness of organizations, make a difference in the lives of users and other stakeholders, drive societal and scientific progress, and obtain key personal benefits. Innovation is also a complex phenomenon. It occurs across a variety of contexts and domains, encompasses numerous phases and activities, and requires unique competency profiles. Despite this complexity, many studies in engineering education focus on specific aspects (e.g., engineering students' abilities to generate original concepts during idea generation), and we still know little about the variety of ways engineering students approach and understand innovation. This study addresses that gap by asking: 1. What are the qualitatively different ways engineering students experience innovation during their engineering projects? 2. What are the structural relationships between the ways engineering students experience innovation? This study utilized phenomenography, a qualitative research method, to explore the above research questions. Thirty-three engineering students were recruited to ensure thorough coverage along four factors suggested by the literature to support differences related to innovation: engineering project experience, academic major, year in school, and gender. Each participant completed a 1-2 hour, semi-structured interview that focused on experiences with and conceptions of innovation. Whole transcripts were analyzed using an eight-stage, iterative, and comparative approach meant to identify a limited number of categories of description (composite ways of experiencing innovation comprised of the experiences of several participants), and the structural relationships between these categories. Phenomenographic analysis revealed eight categories of description that were

    Directory of Open Access Journals (Sweden)

    Salanskis Jean-Michel


    Full Text Available The paper discusses analogies between the way in which infinity is understood and dealt with in mathematics and in Jewish tradition. It begins with recalling the classical debate about infinity in the field of the foundations of mathematics. Reading an important paper by A. Robinson, we come to the conclusion that mathematicians work “as if” infinite totalities existed. They do so by following the rules of their formalized discourse which, at least if it refers to anything at all, also refers to such totalities. The paper describes how, according to Jewish tradition, infinity is also not theological: instead of thinking that they own some infinite being or relate to it, observant Jews follow Jewish law.

    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.

  18. Kerala: a unique model of development. (United States)

    Kannan, K P; Thankappan, K R; Ramankutty, V; Aravindan, K P


    This article capsules health in terms of morbidity, mortality, and maternal and child health; sex ratios, and population density in Kerala state in India from a more expanded report. Kerala state is known for its highly literate and female literate, and poor income population, but its well advanced state of demographic transition. There is a declining population growth rate, a high average marriage age, a low fertility rate, and a high degree of population mobility. One of the unique features of Kerala is the high female literacy, and the favorable position of women in decision making and a matrilineal inheritance mode. The rights of the poor and underprivileged have been upheld. The largest part of government revenue is spent on education followed by health. Traditional healing systems such the ayurveda are strong in Kerala, and Christian missionaries have contributed to a caring tradition. Morbidity is high and mortality is low because medical interventions have affected morality only. The reduction of poverty and environmentally related diseases has not been accomplished inspite of land reform, mass schooling, and general egalitarian policies. Mortality declines and a decline in birth rates have lead to a more adult and aged population, which increases the prevalence of chronic degenerative diseases. Historically, the death rate in Kerala was always lower (25/1000 in 1930 and 6.4 in 1986). The gains in mortality were made in reducing infant mortality (27/1000), which is 4 times less than India as a whole and comparable to Korea, Panama, Yugoslavia, Sri Lanka, and Colombia. Lower female mortality occurs in the 0-4 years. Life expectancy which was the same as India's in 1930 is currently 12 years higher than India's. Females have a higher expectation of life. The sex ratio in 1981 was 1032 compared to India's of 935. Kerala had almost replacement level in 1985. The crude birth rate is 21 versus 32 for India. In addition to the decline in death rates of those 5

  20. My Way in Archaeomagnetism (United States)

    Kovacheva, Mary


    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

  1. Their Name is Half-Way

    Directory of Open Access Journals (Sweden)

    Elena Bagina


    Full Text Available The article is devoted to the phenomenon of the Soviet architecture of the late 1950s – 60s. The name of the article is “Their name is halfway”. It expresses the sense of all the processes occurring both in society and architecture during the Khrushchev Thaw. Developing the socalled Stalin’s Empire in the 1930-1950s, the masters of architecture had travelled only half the way. If the power had not abruptly stopped this movement, we would probably have a unique modern architecture dissimilar to the “international style”. The collapse of the Soviet Union stopped the evolution of architecture again: the unique features of the Soviet architecture of the 1960s ceased to develop. Architects were carried away with ironic games of postmodernism, which led them to deadlock.

  2. Uniqueness conditions for finitely dependent random fields

    Dobrushin, R.L.; Pecherski, E.A.


    The authors consider a random field for which uniqueness and some additional conditions guaranteeing that the correlations between the variables of the field decrease rapidly enough with the distance between the values of the parameter occur. The main result of the paper states that in such a case uniqueness is true for any other field with transition probabilities sufficiently close to those of the original field. Then they apply this result to some ''degenerate'' classes of random fields for which one can check this condition of correlation to decay, and thus obtain some new conditions of uniqueness. (Auth.)

  3. Two Galaxies for a Unique Event (United States)


    To celebrate the 100 Hours of Astronomy, ESO is sharing two stunning images of unusual galaxies, both belonging to the Sculptor group of galaxies. The images, obtained at two of ESO's observatories at La Silla and Paranal in Chile, illustrate the beauty of astronomy. ESO PR Photo 14a/09 Irregular Galaxy NGC 55 ESO PR Photo 14b/09 Spiral Galaxy NGC 7793 As part of the International Year of Astronomy 2009 Cornerstone project, 100 Hours of Astronomy, the ambitious "Around the World in 80 Telescopes" event is a unique live webcast over 24 hours, following night and day around the globe to some of the most advanced observatories on and off the planet. To provide a long-lasting memory of this amazing world tour, observatories worldwide are revealing wonderful, and previously unseen, astronomical images. For its part, ESO is releasing outstanding pictures of two galaxies, observed with telescopes at the La Silla and Paranal observatories. The first of these depicts the irregular galaxy NGC 55, a member of the prominent Sculptor group of galaxies in the southern constellation of Sculptor. The galaxy is about 70 000 light-years across, that is, a little bit smaller than our own Milky Way. NGC 55 actually resembles more our galactic neighbour, the Large Magellanic Cloud (LMC), although the LMC is seen face-on, whilst NGC 55 is edge-on. By studying about 20 planetary nebulae in this image, a team of astronomers found that NGC 55 is located about 7.5 million light-years away. They also found that the galaxy might be forming a bound pair with the gorgeous spiral galaxy NGC 300 . Planetary nebulae are the final blooming of Sun-like stars before their retirement as white dwarfs. This striking image of NGC 55, obtained with the Wide Field Imager on the 2.2-metre MPG/ESO telescope at La Silla, is dusted with a flurry of reddish nebulae, created by young, hot massive stars. Some of the more extended ones are not unlike those seen in the LMC, such as the Tarantula Nebula. The quality

  4. A smarter way to network. (United States)

    Cross, Rob; Thomas, Robert


    The adage "It's not what you know, it's who you know" is true. The right social network can have a huge impact on your success. But many people have misguided ideas about what makes a network strong: They believe the key is having a large circle filled with high-powered contacts. That's not the right approach, say Cross, of UVA's McIntire School of Commerce, and Thomas, of the Accenture Institute for High Performance. The authors, who have spent years researching how organizations can capitalize on employees' social networks, have seen that the happiest, highest-performing executives have a different kind of network: select but diverse, made up of high-quality relationships with people who come from varying spheres and from up and down the corporate ladder. Effective networks typically range in size from 12 to 18 people. They help managers learn, make decisions with less bias, and grow personally. Cross and Thomas have found that they include six critical kinds of connections: people who provide information, ideas, or expertise; formally and informally powerful people, who offer mentoring and political support; people who give developmental feedback; people who lend personal support; people who increase your sense of purpose or worth; and people who promote work/life balance. Moreover, the best kind of connections are "energizers"--positive, trustworthy individuals who enjoy other people and always see opportunities, even in challenging situations. If your network doesn't look like this, you can follow a four-step process to improve it. You'll need to identify who your connections are and what they offer you, back away from redundant and energy-draining connections, fill holes in your network with the right kind of people, and work to make the most of your contacts. Do this, and in due course, you'll have a network that steers the best opportunities, ideas, and talent your way.

  5. Tattoos and piercings: bodily expressions of uniqueness? (United States)

    Tiggemann, Marika; Hopkins, Louise A


    The study aimed to investigate the motivations underlying the body modification practices of tattooing and piercing. There were 80 participants recruited from an Australian music store, who provided descriptions of their tattoos and piercings and completed measures of need for uniqueness, appearance investment and distinctive appearance investment. It was found that tattooed individuals scored significantly higher on need for uniqueness than non-tattooed individuals. Further, individuals with conventional ear piercings scored significantly lower on need for uniqueness than individuals with no piercings or with facial and body piercings. Neither appearance investment nor distinctive appearance investment differed significantly among tattoo or piercing status groups. Strength of identification with music was significantly correlated with number of tattoos, but not number of piercings. It was concluded that tattooing, but not body piercing, represents a bodily expression of uniqueness. Copyright © 2011 Elsevier Ltd. All rights reserved.

  8. Modularity, comparative cognition and human uniqueness. (United States)

    Shettleworth, Sara J


    Darwin's claim 'that the difference in mind between man and the higher animals … is certainly one of degree and not of kind' is at the core of the comparative study of cognition. Recent research provides unprecedented support for Darwin's claim as well as new reasons to question it, stimulating new theories of human cognitive uniqueness. This article compares and evaluates approaches to such theories. Some prominent theories propose sweeping domain-general characterizations of the difference in cognitive capabilities and/or mechanisms between adult humans and other animals. Dual-process theories for some cognitive domains propose that adult human cognition shares simple basic processes with that of other animals while additionally including slower-developing and more explicit uniquely human processes. These theories are consistent with a modular account of cognition and the 'core knowledge' account of children's cognitive development. A complementary proposal is that human infants have unique social and/or cognitive adaptations for uniquely human learning. A view of human cognitive architecture as a mosaic of unique and species-general modular and domain-general processes together with a focus on uniquely human developmental mechanisms is consistent with modern evolutionary-developmental biology and suggests new questions for comparative research.

  9. A Glimpse of the Young Milky Way (United States)


    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

  14. Learning Landscapes: Playing the Way to Learning and Engagement in Public Spaces

    Directory of Open Access Journals (Sweden)

    Brenna Hassinger-Das


    Full Text Available Children from under-resourced communities regularly enter formal schooling lagging behind their peers. These deficits in areas such as language development, reading readiness, and even in the kind of spatial skills that predict later mathematical knowledge, may persist throughout their lifespan. To address such gaps, policymakers have focused largely on schooling as the great equalizer. Yet, children only spend 20% of their waking hours in school. How can developmental scientists and educators address this “other 80%” for the benefit of children’s development? One answer is the Learning Landscapes initiative, which involves crafting carefully planned play experiences that focus on learning outcomes, particularly for children and families from under-resourced communities. Playful learning, a broad pedagogical approach featuring child-directed play methods, provides a unique way to foster learning and engagement organically within the built environment. Learning Landscapes already incorporates several well-documented projects. The Ultimate Block Party brought over 50,000 people to Central Park to engage in playful learning activities. Supermarkets became hotspots for caregiver-child interaction by simply adding prompts for caregiver-child interaction through signage in everyday “trapped” experiences. Urban Thinkscape transformed a bus stop and adjacent lot into a hub for playful learning while families were waiting for public transportation. Finally, Parkopolis is a life-size human board game that fosters STEM and reasoning skills in public spaces. This paper reflects on data from these projects while reflecting on lessons learned and future directions.

  16. Administrative relationships between medical schools and community preceptors. (United States)

    Walling, A D; Sutton, L D; Gold, J


    To determine the current administrative relationships between medical schools and community preceptors, with special emphasis on arrangements for academic appointment, review, and promotion. In 1999, administrative contacts at all 126 U.S. allopathic medical schools were mailed a ten-item questionnaire to elicit information concerning the current practices of the schools regarding community preceptors, who were defined as volunteer or part-time physician faculty, primarily practicing at non-university-owned facilities, who contribute to medical students' and/or residents' education in various specified ways. Responses were received from 71 (56%) of the schools; they were in general a representative sample of U.S. medical schools. The numbers of preceptors per school ranged from 40 to 3,500. Sixty-seven percent of reporting schools identified clinical departments as the main administrative interface with preceptors. Only three schools used a central office; none exclusively used a regionalized system. Forty-four schools (63.8%) reported using formal written criteria for all preceptor appointments. Sixty-six schools (93%) used consistent academic titling systems, with 83.3% using titles including the word "clinical." Thirty-three schools (47.8%) reported that their departments conducted regular preceptor reviews; an additional 28 reported reviews by some departments. Preceptors were eligible for promotion at 94.4% of the responding schools. At 46.8%, specific promotion criteria exist; four schools were developing such criteria. Preceptors' interest in academic promotion was perceived to be moderate or low. A substantial proportion of U.S. medical schools have taken action to recognize preceptors as a unique faculty group. The comments received indicate that this is an active area of development in faculty affairs policy.

  2. Using Quantum Confinement to Uniquely Identify Devices (United States)

    Roberts, J.; Bagci, I. E.; Zawawi, M. A. M.; Sexton, J.; Hulbert, N.; Noori, Y. J.; Young, M. P.; Woodhead, C. S.; Missous, M.; Migliorato, M. A.; Roedig, U.; Young, R. J.


    Modern technology unintentionally provides resources that enable the trust of everyday interactions to be undermined. Some authentication schemes address this issue using devices that give a unique output in response to a challenge. These signatures are generated by hard-to-predict physical responses derived from structural characteristics, which lend themselves to two different architectures, known as unique objects (UNOs) and physically unclonable functions (PUFs). The classical design of UNOs and PUFs limits their size and, in some cases, their security. Here we show that quantum confinement lends itself to the provision of unique identities at the nanoscale, by using fluctuations in tunnelling measurements through quantum wells in resonant tunnelling diodes (RTDs). This provides an uncomplicated measurement of identity without conventional resource limitations whilst providing robust security. The confined energy levels are highly sensitive to the specific nanostructure within each RTD, resulting in a distinct tunnelling spectrum for every device, as they contain a unique and unpredictable structure that is presently impossible to clone. This new class of authentication device operates with minimal resources in simple electronic structures above room temperature.

  3. An evolutionary concept analysis of school violence: from bullying to death. (United States)

    Jones, Sandra N; Waite, Roberta; Clements, Paul Thomas


    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.

  9. [Uniqueness seeking behavior as a self-verification: an alternative approach to the study of uniqueness]. (United States)

    Yamaoka, S


    Uniqueness theory explains that extremely high perceived similarity between self and others evokes negative emotional reactions and causes uniqueness seeking behavior. However, the theory conceptualizes similarity so ambiguously that it appears to suffer from low predictive validity. The purpose of the current article is to propose an alternative explanation of uniqueness seeking behavior. It posits that perceived uniqueness deprivation is a threat to self-concepts, and therefore causes self-verification behavior. Two levels of self verification are conceived: one based on personal categorization and the other on social categorization. The present approach regards uniqueness seeking behavior as the personal-level self verification. To test these propositions, a 2 (very high or moderate similarity information) x 2 (with or without outgroup information) x 2 (high or low need for uniqueness) between-subject factorial-design experiment was conducted with 95 university students. Results supported the self-verification approach, and were discussed in terms of effects of uniqueness deprivation, levels of self-categorization, and individual differences in need for uniqueness.

    Two-way relaying in wireless systems has initiated a large research effort during the past few years. Nevertheless, it represents only a specific traffic pattern and it is of interest to investigate other traffic patterns where such a simultaneous processing of information flows can bring...... performance advantage. In this paper we consider a \\emph{four-way relaying} multiple-input multiple-output (MIMO) scenario, where each of the two Mobile Stations (MSs) has a two-way connection to the same Base Station (BS), while each connection is through a dedicated Relay Station (RS). The RSs are placed...... the sum-rate of the new scheme for Decode-and-Forward (DF) operational model for the RS. We compare the performance with state-of-the-art reference schemes, based on two-way relaying with DF. The results indicate that the sum-rate of the two-phase four-way relaying scheme largely outperforms the four...

    Brown, B. A.; Leisawitz, D.; Boyd, P. T.; Digel, S. W.; Friedlander, J.; Kessel, R. L.; Smale, A. P.


    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 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 or from the ASP catalog. The Multiwavelength Milky Way project is sponsored by the Astrophysics Data Facility at NASA's Goddard Space Flight Center.

  18. Uniqueness and non-uniqueness of semigroups generated by singular diffusion operators

    CERN Document Server

    Eberle, Andreas


    This book addresses both probabilists working on diffusion processes and analysts interested in linear parabolic partial differential equations with singular coefficients. The central question discussed is whether a given diffusion operator, i.e., a second order linear differential operator without zeroth order term, which is a priori defined on test functions over some (finite or infinite dimensional) state space only, uniquely determines a strongly continuous semigroup on a corresponding weighted Lp space. Particular emphasis is placed on phenomena causing non-uniqueness, as well as on the relation between different notions of uniqueness appearing in analytic and probabilistic contexts.

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

    Directory of Open Access Journals (Sweden)

    Gijsbert van den Brink


    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

  5. Unique properties of Drosophila spermatocyte primary cilia

    Directory of Open Access Journals (Sweden)

    Maria Giovanna Riparbelli


    The primary cilium is an essential organelle required for animal development and adult homeostasis that is found on most animal cells. The primary cilium contains a microtubule-based axoneme cytoskeleton that typically grows from the mother centriole in G0/G1 phase of the cell cycle as a membrane-bound compartment that protrudes from the cell surface. A unique system of bidirectional transport, intraflagellar transport (IFT, maintains the structure and function of cilia. While the axoneme is dynamic, growing and shrinking at its tip, at the same time it is very stable to the effects of microtubule-targeting drugs. The primary cilia found on Drosophila spermatocytes diverge from the general rules of primary cilium biology in several respects. Among these unique attributes, spermatocyte cilia assemble from all four centrioles in an IFT-independent manner in G2 phase, and persist continuously through two cell divisions. Here, we show that Drosophila spermatocyte primary cilia are extremely sensitive to microtubule-targeting drugs, unlike their mammalian counterparts. Spermatocyte cilia and their axonemes fail to assemble or be maintained upon nocodazole treatment, while centriole replication appears unperturbed. On the other hand, paclitaxel (Taxol, a microtubule-stabilizing drug, disrupted transition zone assembly and anchoring to the plasma membrane while causing spermatocyte primary cilia to grow extensively long during the assembly/elongation phase, but did not overtly affect the centrioles. However, once assembled to their mature length, spermatocyte cilia appeared unaffected by Taxol. The effects of these drugs on axoneme dynamics further demonstrate that spermatocyte primary cilia are endowed with unique assembly properties.

  6. School children's reasoning about school rules


    Thornberg, Robert


    School rules are usually associated with classroom management and school discipline. However, rules also define ways of thinking about oneself and the world. Rules are guidelines for actions and for the evaluation of actions in terms of good and bad, or right and wrong, and therefore a part of moral or values education in school. This study is a part of a larger ethnographic study on values education in the everyday life of school. Here the focus is on school rules and students' reasoning abo...

  7. Unique supply function equilibrium with capacity constraints

    International Nuclear Information System (INIS)

    Holmberg, Paer


    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.

    International Nuclear Information System (INIS)

    Harrach, Bastian


    A prominent result of Arridge and Lionheart (1998 Opt. Lett. 23 882–4) demonstrates that it is in general not possible to simultaneously recover both the diffusion (aka scattering) and the absorption coefficient in steady-state (dc) diffusion-based optical tomography. In this work we show that it suffices to restrict ourselves to piecewise constant diffusion and piecewise analytic absorption coefficients to regain uniqueness. Under this condition both parameters can simultaneously be determined from complete measurement data on an arbitrarily small part of the boundary

  9. A unique funding opportunity for public health in Texas. (United States)

    Schlenker, Thomas; Huber, Carol A


    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.

  11. On the non-uniqueness of the nodal mathematical adjoint

    International Nuclear Information System (INIS)

    Müller, Erwin


    Highlights: • We evaluate three CMFD schemes for computing the nodal mathematical adjoint. • The nodal mathematical adjoint is not unique and can be non-positive (nonphysical). • Adjoint and forward eigenmodes are compatible if produced by the same CMFD method. • In nodal applications the excited eigenmodes are purely mathematical entities. - Abstract: Computation of the neutron adjoint flux within the framework of modern nodal diffusion methods is often facilitated by reducing the nodal equation system for the forward flux into a simpler coarse-mesh finite-difference form and then transposing the resultant matrix equations. The solution to the transposed problem is known as the nodal mathematical adjoint. Since the coarse-mesh finite-difference reduction of a given nodal formulation can be obtained in a number of ways, different nodal mathematical adjoint solutions can be computed. This non-uniqueness of the nodal mathematical adjoint challenges the credibility of the reduction strategy and demands a verdict as to its suitability in practical applications. This is the matter under consideration in this paper. A selected number of coarse-mesh finite-difference reduction schemes are described and compared. Numerical calculations are utilised to illustrate the differences in the adjoint solutions as well as to appraise the impact on such common applications as the computation of core point kinetics parameters. Recommendations are made for the proper application of the coarse-mesh finite-difference reduction approach to the nodal mathematical adjoint problem

  12. Arm coordination in octopus crawling involves unique motor control strategies. (United States)

    Levy, Guy; Flash, Tamar; Hochner, Binyamin


    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. Copyright © 2015 Elsevier Ltd.

  13. Unmanned Aerial Vehicles unique cost estimating requirements (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.

  14. Young children's preference for unique owned objects. (United States)

    Gelman, Susan A; Davidson, Natalie S


    An important aspect of human thought is the value we place on unique individuals. Adults place higher value on authentic works of art than exact replicas, and young children at times value their original possessions over exact duplicates. What is the scope of this preference in early childhood, and when do children understand its subjective nature? On a series of trials, we asked three-year-olds (N=36) to choose between two toys for either themselves or the researcher: an old (visibly used) toy vs. a new (more attractive) toy matched in type and appearance (e.g., old vs. brand-new blanket). Focal pairs contrasted the child's own toy with a matched new object; Control pairs contrasted toys the child had never seen before. Children preferred the old toys for Focal pairs only, and treated their own preferences as not shared by the researcher. By 3years of age, young children place special value on unique individuals, and understand the subjective nature of that value. Copyright © 2016 Elsevier B.V. All rights reserved.

  15. Event segmentation ability uniquely predicts event memory. (United States)

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


    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 79years 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. Copyright © 2013 Elsevier B.V. All rights reserved.

  3. Is physical space unique or optional

    International Nuclear Information System (INIS)

    Ekstein, H.; Centre National de la Recherche Scientifique, 13 - Marseille


    There are two concepts of the physical space-time. One, S(F), is that of a fixed arena in which events take place. The other S(D), is that of a space-time shaped by events. The second depends on the state (initial conditions) or on the external field, the first does not. The main assertions of the present paper are: 1) the fixed space-time S(F) is neither incompatibles with nor made superfluous, by Einstein's theory. S(F) is experimentally explorable, unique, and probably identical with Minkowski space M. 2) The dynamical space S(D) is largely optional. It can be chosen to be M, but the natural choice is Einstein's pseudo-Riemanian manifold [fr

  6. Unique computer system for safeguards use

    International Nuclear Information System (INIS)

    Kuckertz, T.H.; Pratt, J.C.


    Microprocessors have been used to implement specialized scientific data processing systems since 1976. One such system, the LeCroy 3500, is presently being used by the Detection and Verification Group of the Energy Division at Los Alamos National Laboratory for a large variety of tasks involving measurement of various nuclear parameters associated with radioactive materials. The system is unique because it can do not only sophisticated pulse height and multi-scale analyses but also other analyses that are limited only by the availability fo CAMAC modules that would acquire data from exotic experiments. The system is also field portable which extends the range of experiments that it can control. Four applications of this system are described in this paper: (1) plutonium storage vault monitoring, (2) coded aperture image reconstruction, (3) spatial distribution of gamma radiation, and (4) nuclear waste management. 7 figures

  7. 2XIIB vacuum vessel: a unique design

    International Nuclear Information System (INIS)

    Hibbs, S.M.; Calderon, M.O.


    The 2XIIB mirror confinement experiment makes unique demands on its vacuum system. The confinement coil set encloses a cavity whose surface is comprised of both simple and compound curves. Within this cavity and at the core of the machine is the operating vacuum which is on the order of 10 -9 Torr. The vacuum container fits inside the cavity, presenting an inside surface suitable for titanium getter pumping and a means of removing the heat load imposed by incandescent sublimator wires. In addition, the cavity is constructed of nonmagnetic and nonconducting materials (nonmetals) to avoid distortion of the pulsed confinement field. It is also isolated from mechanical shocks induced in the machine's main structure when the coils are pulsed. This paper describes the design, construction, and operation of the 2XIIB high-vacuum vessel that has been performing successfully since early 1974

  8. The unique ethics of sports medicine. (United States)

    Johnson, Rob


    The ethical code by which physicians traditionally conduct themselves is based on the relationship between the physician and the patient: both work toward the goal of improving or maintaining health. Constraints on this relationship may be behaviors of patient choice (tobacco use, excessive alcohol use, sedentary behavior, and so on). The athlete-physician relationship is ethically different. Influences such as the physician's employer, the athlete's desire to play with pain and injury, and the economic consequences of playing or not complicate medical decisions. This perspective suggests something different and even unique about the ethics of the sports medicine practitioner. This article explores the differences fostering the ethical tight ropes that sports physicians walk in their sports medicine practices.

  9. MRI: unique costing and pricing issues. (United States)

    Schwartz, H W; Jarl, D F


    Acquisition of magnetic resonance imaging (MRI) involves a plethora of costs not traditionally encountered in radiology procedure cost accounting models. Experiences with MRI gained at the University of Minnesota Hospitals and Clinics during 1984 uncovered a wide variety of unique costing issues which were eventually identified at the time when the MRI hospital charge was being established. Our experience at UMHC can provide those radiology departments now acquiring MRI with an earlier awareness of these special costing issues, hopefully resulting in better and more timely data collection. Current reimbursement and pricing issues are also having a dramatic impact on MRI costs at each institution and must be assessed in terms of third-party payor intentions.

  19. Violence in the School Setting: A School Nurse Perspective. (United States)

    King, Kate K


    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.

Therefore, we identified plasma and urine metabolites associated with recent beer intake by untargeted metabolomics and established a characteristic metabolite pattern representing raw materials and beer production as a qualitative biomarker of beer intake. In a randomized, crossover, single-blinded meal study (MSt1), 18 participants were given, one at a time, four different test beverages: strong, regular, and nonalcoholic beers and a soft drink. Four participants were assigned to have two additional beers (MSt2). In addition to plasma and urine samples, test beverages, wort, and hops extract were analyzed by UPLC-QTOF. A unique metabolite pattern reflecting beer metabolome, including metabolites derived from beer raw material (i.e., N-methyl tyramine sulfate and the sum of iso-α-acids and tricyclohumols) and the production process (i.e., pyro-glutamyl proline and 2-ethyl malate), was selected to establish a compliance biomarker model for detection of beer intake based on MSt1. The model predicted the MSt2 samples collected before and up to 12 h after beer intake correctly (AUC = 1). A biomarker model including four metabolites representing both beer raw materials and production steps provided a specific and accurate tool for measurement of beer consumption.

    Martinez, H.E.; Brown, W.G.; Flamm, B.; James, C.A.; Laskie, R.; Nelson, T.O.; Wedman, D.E.


    A series of unique features have been incorporated into the Advanced Recovery and Integrated Extraction System (ARIES) at the Los Alamos National Laboratory, TA-55 Plutonium Facility. The features enhance the material handling in the process of the dismantlement of nuclear weapon primaries in the glovebox line. Incorporated into these features are the various plutonium process module's different ventilation zone requirements that the material handling systems must meet. These features include a conveyor system that consists of a remotely controlled cart that transverses the length of the conveyor glovebox, can be operated from a remote location and can deliver process components to the entrance of any selected module glovebox. Within the modules there exists linear motion material handling systems with lifting hoist, which are controlled via an Allen Bradley control panel or local control panels. To remove the packaged products from the hot process line, the package is processed through an air lock/electrolytic decontamination process that removes the radioactive contamination from the outside of the package container and allows the package to be removed from the process line

  3. Clinical EPR: Unique Opportunities and Some Challenges (United States)

    Electron paramagnetic resonance (EPR) spectroscopy has been well established as a viable technique for measurement of free radicals and oxygen in biological systems, from in vitro cellular systems to in vivo small animal models of disease. However, the use of EPR in human subjects in the clinical setting, although attractive for a variety of important applications such as oxygen measurement, is challenged with several factors including the need for instrumentation customized for human subjects, probe and regulatory constraints. This paper describes the rationale and development of the first clinical EPR systems for two important clinical applications, namely, measurement of tissue oxygen (oximetry), and radiation dose (dosimetry) in humans. The clinical spectrometers operate at 1.2 GHz frequency and use surface loop resonators capable of providing topical measurements up to 1 cm depth in tissues. Tissue pO2 measurements can be carried out noninvasively and repeatedly after placement of an oxygen-sensitive paramagnetic material (currently India ink) at the site of interest. Our EPR dosimetry system is capable of measuring radiation-induced free radicals in the tooth of irradiated human subjects to determine the exposure dose. These developments offer potential opportunities for clinical dosimetry and oximetry, which include guiding therapy for individual patients with tumors or vascular disease, by monitoring of tissue oxygenation. Further work is in progress to translate this unique technology to routine clinical practice. PMID:24439333

  4. TDRSS S-shuttle unique receiver equipment (United States)

    Weinberg, A.; Schwartz, J. J.; Spearing, R.


    Beginning with STS-9, the Tracking and Date Relay Satellite system (TDRSS) will start providing S- and Ku-band communications and tracking support to the Space Shuttle and its payloads. The most significant element of this support takes place at the TDRSS White Sands Ground Terminal, which processes the Shuttle return link S- and Ku-band signals. While Ku-band hardware available to other TDRSS users is also applied to Ku-Shuttle, stringent S-Shuttle link margins have precluded the application of the standard TDRSS S-band processing equipment to S-Shuttle. It was therfore found necessary to develop a unique S-Shuttle Receiver that embodies state-of-the-art digital technology and processing techniques. This receiver, developed by Motorola, Inc., enhances link margins by 1.5 dB relative to the standard S-band equipment and its bit error rate performance is within a few tenths of a dB of theory. An overview description of the Space Shuttle Receiver Equipment (SSRE) is presented which includes the presentation of block diagrams and salient design features. Selected, measured performance results are also presented.

  6. Hausdorff dimension of unique beta expansions

    International Nuclear Information System (INIS)

    Kong, Derong; Li, Wenxia


    Given an integer N ⩾ 2 and a real number β > 1, let Γ β, N be the set of all x=∑ i=1 ∞ d i /β i with d i  ∈ {0, 1, ···, N − 1} for all i ⩾ 1. The infinite sequence (d i ) is called a β-expansion of x. Let U β,N be the set of all x's in Γ β,N which have unique β-expansions. We give explicit formula of the Hausdorff dimension of U β,N for β in any admissible interval [β L , β U ], where β L is a purely Parry number while β U is a transcendental number whose quasi-greedy expansion of 1 is related to the classical Thue–Morse sequence. This allows us to calculate the Hausdorff dimension of U β,N for almost every β > 1. In particular, this improves the main results of Gábor Kallós (1999, 2001). Moreover, we find that the dimension function f(β) = dim H U β,N fluctuates frequently for β ∈ (1, N). (paper)

  7. Unique type of isolated cardiac valvular amyloidosis

    Directory of Open Access Journals (Sweden)

    Reehana Salma


    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.

    Full Text Available The North Dakota State University, USA, capstone course was developed as a unique model in response to the effort of the Accreditation Board of Engineering and Technology, USA, to streamline and improve design instruction in the curriculum and has steadily evolved to keep pace with the ever-changing technology and the expectations of the profession and the society we serve. A capstone design course by definition should be a design experience for students in the final year before graduation integrating all major design concepts they have learned up until then in the program. Carefully chosen real world projects with design content in all sub-disciplines of civil engineering are assigned in this team-taught course. Faculty and practicing professionals make presentations on design process; project management; leadership in an engineering environment; and public policy; global perspectives in engineering; and professional career and licensure. Practicing professionals also critique the final student presentations. Students work in teams with number of faculty serving as technical consultants, and a faculty mentor for each team to provide non-technical guidance and direction. The course requires students to demonstrate mastery of the curriculum and to work with others in a team environment. Course assessment includes evaluation of the final design, presentations, written technical reports, project design schedule, a project design journal, and reaction papers.

  12. Ways of Viewing Pictorial Plasticity

    Directory of Open Access Journals (Sweden)

    Maarten W. A. Wijntjes


    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.

  14. Perspectives on Psychological Science: Right Way/Wrong Way Symposium. (United States)

    Gunnar, Megan R


    In unpredictable times, it is perhaps even more important to contemplate the direction different fields of science are headed. In this article, I contemplate two directions of psychological science: the increasing integration of the study of psychology with other sciences and the concern of many sciences, including ours, with improving the reproducibility of our findings. Both of these are argued to be "right ways," but these directions also have challenges that, unless carefully addressed, could detract from our ability to move the science of psychology forward. I detail these challenges along with a consideration of how to chart our science through the unpredictable waters we face at this point in history.

  16. Losing memories overnight: a unique form of human amnesia. (United States)

    Smith, Christine N; Frascino, Jennifer C; Kripke, Donald L; McHugh, Paul R; Treisman, Glenn J; Squire, Larry R


    Since an automobile accident in 2005, patient FL has reported difficulty retaining information from one day to the next. During the course of any given day, she describes her memory as normal. However, memory for each day disappears during a night of sleep. She reports good memory for events that occurred before the accident. Although this pattern of memory impairment is, to our knowledge, unique to the medical literature, it was depicted in the fictional film "50 First Dates". On formal testing, FL performed moderately well when trying to remember material that she had learned during the same day, but she exhibited no memory at all for material that she knew had been presented on a previous day. For some tests, unbeknownst to FL, material learned on the previous day was intermixed with material learned on the same day as the test. On these occasions, FL's memory was good. Thus, she was able to remember events from earlier days when memory was tested covertly. FL performed differently in a number of ways from individuals who were instructed to consciously feign her pattern of memory impairment. It was also the impression of those who worked with FL that she believed she had the memory impairment that she described and that she was not intentionally feigning amnesia. On the basis of her neuropsychological findings, together with a normal neurological exam, normal MRI findings, and psychiatric evaluation, we suggest that FL exhibits a unique form of functional amnesia and that its characterization may have been influenced by knowledge of how amnesia was depicted in a popular film. She subsequently improved (and began retaining day-to-day memory) at Johns Hopkins University where she was in a supportive in-patient environment and was shown how to take control of her condition by interrupting her sleep at 4-h intervals.

  17. Peatlands as a unique climatic hotspots (United States)

    Slowinska, S.; Marcisz, K.; Slowinski, M. M.; Blazejczyk, K.; Lamentowicz, M.


    Peatlands are unique environments, often acting as microrefugia of various taxa. High groundwater table, organic soils, specific vegetation and topography are important determinants of their local climatic conditions. However, relations between those determinants are not stable. For example, seasonal changes in weather patterns, hydrological dynamics, and local vegetation may alter microclimate. Additionally, long-term changes are important factor, as for example overgrowing due to significant change of microclimate conditions, what in turn changes geochemical and biological processes in the peat layer. We have been investigating interactions between abiotic and biotic factors of a small Sphagnum mire (ca. 6.0 ha) for over ten years now. The mire is located in Poland in transitional temperate climate and is the only place in polish lowlands where glacial relict Betula nana occurs. Identification of local climate of the mire, its microclimatic differentiation and its influence on surroundings were objectives of the study. We recorded water level fluctuations, photosynthetically active radiation (PAR), air temperature and humidity, and peat temperature at five monitoring plots at the mire and observed significant differences between them. We also investigated Sphagnum mosses growth and testate amoeba diversity and community structure to understand biological response of those differences. We observed that local climate of the mire was significantly different from open area reference place, it was much colder especially during nights. The average minimal temperature at the height 30 cm for growing seasons 2010-2012 was 3.7oC lower there and ground frosts occurred even in the summer. The climate of the mire affected the forest directly adjacent to it, and depending on weather conditions the strength and the distance of this interaction was different. Our results show that micro-environmental changes affects on biological processes and should be taken into consideration

  18. Lourdes: A uniquely Catholic approach to medicine. (United States)

    Dichoso, Travis Jon


    As an American medical student, I spent the summer break between my first and second year in Lourdes, France, the site where the Immaculate Conception appeared eighteen times to St. Bernadette in 1858 as proclaimed approved by the Catholic Church and whose water is associated with over seven thousand unexplained cures. During this time I volunteered with St. Joseph's Service and Poste Secour, followed several medical teams taking care of large pilgrim groups, and shadowed Dr. Alessandro de Franciscis the president of Le Bureau des Constations Médicales, the office in Lourdes charged with investigating claims of miracles. Through my experiences, I found the mission of medicine in Lourdes to be twofold: to provide the critical care needed to give sick persons the chance to transform their experience of disease through their faith; and secondly, through the efforts of the Medical Bureau, to be an instrument by which we can comprehend the wonders of the work of God. I conclude that this twofold mission should inform the work of every Catholic in health care or research, and Lourdes provides the venue par excellence to cultivate this mission. Lay Summary: Lourdes is a pilgrimage site in southern France that has been associated with medical miracles for the past 150 years. The site is unique in that throughout its history, physicians, of any or no faith, have been invited to participate in the proceedings of the investigations of each claimed cure. The investigations have formalized into a process handled by the Lourdes Medical Bureau and the Lourdes International Medical Association. Travis Dichoso, an American medical student, writes about his experiences as part of this process.

  19. Evolution of a Unique Systems Engineering Capability

    Energy Technology Data Exchange (ETDEWEB)

    Robert M. Caliva; James A. Murphy; Kyle B. Oswald


    The Idaho National Laboratory (INL) is a science-based, applied engineering laboratory dedicated to supporting U.S. Department of Energy missions in nuclear and energy research, science, and national security. 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.

  1. Two-way digital communications (United States)

    Glenn, William E.; Daly, Ed


    The communications industry has been rapidly converting from analog to digital communications for audio, video, and data. The initial applications have been concentrating on point-to-multipoint transmission. Currently, a new revolution is occurring in which two-way point-to-point transmission is a rapidly growing market. The system designs for video compression developed for point-to-multipoint transmission are unsuitable for this new market as well as for satellite based video encoding. A new system developed by the Space Communications Technology Center has been designed to address both of these newer applications. An update on the system performance and design will be given.

  4. Unitary Evolution as a Uniqueness Criterion (United States)

    Cortez, J.; Mena Marugán, G. A.; Olmedo, J.; Velhinho, J. M.


    It is well known that the process of quantizing field theories is plagued with ambiguities. First, there is ambiguity in the choice of basic variables describing the system. Second, once a choice of field variables has been made, there is ambiguity concerning the selection of a quantum representation of the corresponding canonical commutation relations. The natural strategy to remove these ambiguities is to demand positivity of energy and to invoke symmetries, namely by requiring that classical symmetries become unitarily implemented in the quantum realm. The success of this strategy depends, however, on the existence of a sufficiently large group of symmetries, usually including time-translation invariance. These criteria are therefore generally insufficient in non-stationary situations, as is typical for free fields in curved spacetimes. Recently, the criterion of unitary implementation of the dynamics has been proposed in order to select a unique quantization in the context of manifestly non-stationary systems. Specifically, the unitarity criterion, together with the requirement of invariance under spatial symmetries, has been successfully employed to remove the ambiguities in the quantization of linearly polarized Gowdy models as well as in the quantization of a scalar field with time varying mass, propagating in a static background whose spatial topology is either of a d-sphere (with d = 1, 2, 3) or a three torus. Following Ref. 3, we will see here that the symmetry and unitarity criteria allows for a complete removal of the ambiguities in the quantization of scalar fields propagating in static spacetimes with compact spatial sections, obeying field equations with an explicitly time-dependent mass, of the form ddot φ - Δ φ + s(t)φ = 0 . These results apply in particular to free fields in spacetimes which, like e.g. in the closed FRW models, are conformal to a static spacetime, by means of an exclusively time-dependent conformal factor. In fact, in such

  10. A new way of telling earthquake stories: MOBEE - the MOBile Earthquake Exhibition (United States)

    Tataru, Dragos; Toma-Danila, Dragos; Nastase, Eduard


    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. It also involves

    Full Text Available This article provides an overview of the Romanian process to join the euro, under the terms of the current economic-financial crisis. The purpose of this study is to analyze the degree of achieving real and nominal convergence criteria, along with offering perspectives regarding European monetary integration. The adoption of the unique currency represents an important challenge and opportunity for Romania during the post-adherence period, which forces the political and administrative environment to conceive and implement coherent and responsible politics meant to ensure a simultaneous fulfillment of nominal and real convergence criteria of the Romanian economy. The results of this analysis illustrate that, despite the fact that the Romanian economy recorded significant progresses on the fulfillment of the Maastricht criteria, the current economic context has introduced an additional uncertainty factor and significantly made the adoption of a single currency harder, and the enforcement of real convergence criteria has become much more difficult. Under these circumstances, the National Bank of Romania gave up the target that 2015 represented, and also the one of establishing a new target-date to enter the eurozone, the perspective of joining a single currency exceeding the horizon of this decade. In order to achieve a real, profound and sustainable reorganization of the Romanian economy and to successfully recover the discrepancies between Romania and the EU standards, the road to the euro must be paved with much caution and wisdom.

    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.

  15. Tibialis Posterior Tenosynovitis: A Unique Musculoskeletal Manifestation of Gout. (United States)

    Shupper, Peter; Stitik, Todd P


    Extra-articular manifestations of gout can present in several ways, including tenosynovitis. We present a rare case of acute tibialis posterior gouty tenosynovitis. An 82-year-old man with a history of well-controlled gout presented with acute onset of left ankle pain, occurring without inciting event. The medial ankle was slightly erythematous with moderate dorsal-medial swelling and mild dorsal-lateral swelling, with severe tenderness to palpation over the medial retro-malleolar region. Range of motion and manual muscle testing were pain limited throughout. Ultrasound examination revealed a left posterior tibialis tendon sheath tenosynovitis with effusion and overlying soft tissue edema. Tendon sheath aspirate revealed sodium urate crystals and a white blood cell count of 6400/μL. Tendon sheath injection with a mixture of 1% lidocaine and dexamethasone 4 mg resulted in symptom resolution. Repeat ultrasound examination demonstrated no evidence of tibialis posterior tendon sheath effusion. This case is unique not only because acute gouty posterior tibialis tenosynovitis is very rare, particularly in a normouricemic individual, but also because the sonographic evidence of gouty infiltration into the posterior tibialis tendon and overlying subcutaneous tissue considerably aided in arriving at the correct diagnosis in a timely manner.

  16. Mast Cells Produce a Unique Chondroitin Sulfate Epitope. (United States)

    Farrugia, Brooke L; Whitelock, John M; O'Grady, Robert; Caterson, Bruce; Lord, Megan S


    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. © 2016 The Histochemical Society.

    International Nuclear Information System (INIS)

    Fells, I.


    A report is given on a conference held at the Ditchley Foundation, Oxfordshire, entitled 'Nuclear energy: safety, future development and alternative strategies'. Among items discussed were; the current situation, the safety and licensing of power reactors, transport and storage of spent fuel, performance considerations, plant size, costs, problems specific to nuclear power in developing countries, and political considerations. The paradox that despite escalating oil prices and increasing anxiety about the political stability of the Arab oil producers, the nuclear power programme of the developed non-communist world is still in the doldrums was examined and it was felt that the biggest task facing the nuclear power industry is one of educating public and politicians in such a way that a balanced critical approach to the risks and benefits of nuclear power replaces uninformed emotional response.

  18. One-way shared memory

    DEFF Research Database (Denmark)

    Schoeberl, Martin


    Standard multicore processors use the shared main memory via the on-chip caches for communication between cores. However, this form of communication has two limitations: (1) it is hardly time-predictable and therefore not a good solution for real-time systems and (2) this single shared memory...... is a bottleneck in the system. This paper presents a communication architecture for time-predictable multicore systems where core-local memories are distributed on the chip. A network-on-chip constantly copies data from a sender core-local memory to a receiver core-local memory. As this copying is performed...... in one direction we call this architecture a one-way shared memory. With the use of time-division multiplexing for the memory accesses and the network-on-chip routers we achieve a time-predictable solution where the communication latency and bandwidth can be bounded.

  2. MYRRHA. An innovative and unique research facility

    Fernandez, Rafaeol; Neerdael, Bernard; Schyns, Marc; Dyck, Steven Van; Michiels, Sidney; Ait Abderrahim, Hamid, E-mail: [Belgian Nuclear Research Centre (SCK-CEN), Mol (Belgium)


    The MYRRHA project started in 1998 by SCK{center_dot}CEN in collaboration with Ion Beam Applications (IBA, Louvain-la-Neuve), as an upgrade of the ADONIS project. MYRRHA is designed as a multi-purpose irradiation facility in order to support research programmes on fission and fusion reactor structural materials and nuclear fuel development. Applications of these are found in Accelerator Driven Systems (ADS) systems and in present generation as well as in next generation critical reactors. The first objective of MYRRHA however, will be to demonstrate on one hand the ADS concept at a reasonable power level and on the other hand the technological feasibility of transmutation of Minor Actinides (MA) and Long-Lived Fission Products (LLFP) arising from the reprocessing of radioactive waste. MYRRHA will also help the development of the Pb-alloys technology needed for the LFR (Lead Fast Reactor) Gen.IV concept. Transmutation of MA can be completed in an efficient way in fast neutron spectrum facilities. Both critical reactors and sub-critical ADS are potential candidates as dedicated transmutation systems. However, critical reactors, heavily loaded with fuel containing large amounts of MA, pose safety problems caused by unfavourable reactivity coefficients due to the little delayed neutron fraction. A sub-critical ADS operates in a flexible and safe manner even with a core loading containing a high amount of MA leading to achieve a high efficient transmutation. Thus, the sub-criticality is not a virtue but rather a necessity for an efficient and economical burning of the MA. Besides the reduction of the HLW burden, the MYRRHA project will serve the purpose of developing the lead alloys technology as a reactor coolant that can be used in one of the Generation IV reactor concepts namely the Lead Fast Reactor (LFR). Although carrying out the MYRRHA project will lead to the demonstration of the efficient and safe transmutation of MA in ADS systems as the ultimate goal the

  6. Logic without unique readability - a study of semantic and syntactic ambiguity

    DEFF Research Database (Denmark)

    Bentzen, Martin Mose

    One of the main reasons for introducing a formal language is to remove ambiguity, the possibility of assigning several meanings to a linguistic expression. Typically, this is achieved through ensuring unique readability of formulas by using brackets (or another convention, such as Polish notation...... not hold true universally. Whereas e.g. scope ambiguities in natural languages have been studied extensively, ambiguous formal languages have not been the focus of in depth research. Here, we lift the assumption of unique readability by omitting the brackets from propositional logic, making it possible...... to formally distinguish between syntactic and semantic ambiguity. A valuation then amounts to a semantic disambiguation, and rather than a unique valuation (truth value), there is a set of valuations corresponding to ways a formula could have been constructed. We show what happens to familiar concepts...

  7. The UNIQUe Label: Supporting a Culture of Innovation and Quality in Higher Education (United States)

    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.

    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....

  10. Prices on the way up?

    International Nuclear Information System (INIS)



    It may have taken until the very last day of the month, but prices are finally on the way up. On July 31, a US utility concluded at least two transactions for a minimum of 250,000 lbs U3O8 equivalent, pushing the top of NUKEM's price range up 10 cents. After three months with prices languishing below US$7.85, the price range now stands at US$7.75-$7.95. The pace of new demand held steady in July versus June, with more than 3.4 million lbs equivalent in new requests entering the market. There was one difference: The new demand in July was characterized by longer lead time. Most new demand in June required delivery by the end of the fourth quarter, a lead time of about 3 to 6 months. In July, buyers accepted delivery anywhere from 4 to 9 months out, with most delivery requests landing in 1993. This jump in lead times is largely due to one seller in the market offering first and second quarter 1993 deliveries near the bottom of the price range to utilities with flexible needs

  11. Responses to The Way Forward

    International Nuclear Information System (INIS)


    In November 1987 United Kingdom Nirex Limited launched a discussion document entitled The Way Forward. The stated aims of the document were to promote discussion and to seek constructive contributions to the task of ensuring that radioactive waste is managed safely. It further aimed to promote public understanding of the issues involved and to stimulate comment which would assist Nirex in developing acceptable proposals for the disposal of radioactive waste. From the 2,526 replies received the main findings are: there is a clear welcome for the consultation exercise among local authorities and the majority of responding organisations; there is no overall unanimity of view; there appears to be little support for the under sea-bed accessed off-shore repository; safety is judged to be the paramount factor for all consultees, though clearly views differ as to how best to achieve this. The safe transport of wastes is the next major area of concern; views differ as to whether areas of high amenity value should be excluded from consideration at the outset, though the majority view is probably that they should be; the monitoring and recoverability of wastes is generally deemed to be important; potential detrimental local economic impact and blight through social stigma associated with the public perception of radioactive waste disposal is also a key concern and there is opposition from local authorities and environmental groups to the use of the Special Development Order procedure for obtaining planning permission for either investigative drilling or subsequent development.

  12. Adapting the Unique Minds Program: Exploring the Feasibility of a Multiple Family Intervention for Children with Learning Disabilities in the Context of Spain. (United States)

    López-Larrosa, Silvia; González-Seijas, Rosa M; Carpenter, John S W


    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.

  13. New ways of insulin delivery. (United States)

    Heinemann, L


    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

  14. The gaming of concussions: a unique intervention in postconcussion syndrome. (United States)

    Lynch, James M; Anderson, Megan; Benton, Brooke; Green, Sue Stanley


    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.

  15. Trials at Sea: Successful Implementation of a Unique Two-Month Professional Development Program (United States)

    Peart, L. W.; Orcutt, B. N.; Fisher, A. T.; Tsuji, T.; Petronotis, K. E.; Iodp Expedition 327 Participants


    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. Close to the beginning of the

  16. A New Approach to Environmentally Safe Unique Identification of Long-Term Stored Copper Canisters

    International Nuclear Information System (INIS)

    Chernikova, D.; Axell, K.; Nordlund, A.


    A new approach to environmentally safe unique identification of long-term stored copper canisters is suggested in this paper. The approach is based on the use of a tungstenbased insert placed inside a copper cask between a top iron lid and a copper lid. The insert/label is marked with unique code in a form of binary number, which is implemented as a combination of holes in the tungsten plate. In order to provide a necessary redundancy of the identifier, the tungsten label marked with few identical binary codes. The position of code (i.e., holes in tungsten) corresponds to a predefined placement of the spent fuel assembles in the iron container. This is in order to avoid any non-uniformity of the gamma background at the canister surface caused by a presence of iron-filled spaces between spent nuclear fuel assembles. Due to the use of the tungsten material gamma rays emitted by the spent fuel assembles are collimated in a specific way because of strong attenuation properties of tungsten. As a result, the variation in the gamma-counting rate in a detector array placed on the top of copper lid provides the distribution of the holes in the tungsten insert or in other words the unique identifier. Thus, this way of identification of copper cask do not impair the integrity of the cask and it offers a way that the information about spent nuclear fuel is legible for a time scale up to a few thousands years.

    Brock, Steen; Christiansen, Tenna Holdorff


    In this paper we examine how the policies formulated by Danish school authorities concerning eating at school are implemented by staff and interpreted by schoolchildren. We use positioning theory in order to analyse how authorities, staff, and children engage in a mutual positioning, within...... and between different moral orders. We conclude that the official food policies are off-target and that school children should instead develop a kind of local citizenship displaying an ability to manoeuvre in between different positions such that this participation expresses a way of belonging to the school...

  18. The Italian Way to Carsharing

    Directory of Open Access Journals (Sweden)

    Antonio Laurino


    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

    Full Text Available "The Tao that can be told is not the eternal Tao. The name that can be named is not the eternal name. The nameless is the beginning of heaven and earth. 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.

    Full Text Available Purpose. The research paper proposes to estimate the effect of heat inertia of the water heating system, in transient operation modes, on the temperature condition in the passenger car, as well as to offer technical solutions intended to reduce the heating system inertia effect and to maintain a stable temperature condition in the passenger car premises in transitional modes of the heating system. Methodology. The author developed the method for controlling the heat transfer of heating system pipes with the help of regulating casing. To control the heating system and the heat transfer of heating pipes, two types of temperature control sensors were used in the passenger car: certain sensors interacted with regulatory casings, while the others interacted with high-voltage tubular heating element control devices. To assess the efficiency of heat interchange regulation of heating pipes and the heating system control, with installed regulating casings, the operation of the heating system with regulating casings and two types of sensors was mathematically modelled. Mathematical modelling used the experimental test data. The results of experimental tests and mathematical modelling were compared. Findings. Currently in operated passenger cars, control of heating appliances is not constructively provided. Automatic maintenance of the set temperature in a passenger car is limited to switching on and off of high-voltage tubular heating elements. The use of regulating casings on heating pipes allows reducing the effects of heat inertia and maintaining stable thermal conditions in a passenger car, using the heating system as a heat accumulator, and also provides the opportunity to realize an individual control of air temperature in the compartment. Originality. For the first time, the paper studied the alternative ways of regulating the temperature condition in a passenger car. Using of the heating system as a heat accumulator. Practical value.

  6. Getting Students Outside: Using Technology as a Way to Stimulate Engagement (United States)

    Boyce, Carrie J.; Mishra, Chandrani; Halverson, Kristy L.; Thomas, Aimée K.


    Informal environments provide students with unique experiences that allow them to actively participate in activities while promoting a positive attitude toward and an increased interest in science. One way to enhance informal science experiences is through the integration of mobile technologies. This integration is particularly useful in engaging underrepresented students in learning science. Our informal environmental science program engages underrepresented, fifth-grade students in an informal learning environment supplemented with mobile tablet technology (iPads). The purpose of this study was to explore how fifth-grade students interacted with nature using mobile technology during a nature hike series. Participants included 55 fifth-grade students from two low-income schools. We found that students used the mobile technology to explore nature and stay engaged throughout the hike. The iPads were used as references, data collectors, and engagement tools. Students had an intense desire in returning to the site and responded positively toward interacting with nature. Prior research has indicated that students in this age group are likely to lose interest in science and the incorporation of field-friendly technology that engages students with nature, not technology alone, is a useful tool for keeping students interested in science.

  7. Fifty years in fusion and the way forward

    International Nuclear Information System (INIS)

    Jacquinot, J.


    This particular 'Fusion Pioneers Memorial lecture' was given 50 years after the first historical FEC conference in 1958. It was a unique occasion to perform a global reflection on thermonuclear fusion which is summarized in this paper. We first consider the case for fusion energy then move on to the scientific achievements during the past five decades. Finally, the lessons drawn from the past give a framework to consider the challenges ahead of us. The 1958 pioneers had the vision of the vital importance of international collaboration to succeed in this unique endeavour. Fifty years later, this vision has amply proven its worth. Looking at the way forward, this vision constitutes a strong basis to harness fusion energy in the decades to come.

  8. A unique view on male infertility around the globe. (United States)

    Agarwal, Ashok; Mulgund, Aditi; Hamada, Alaa; Chyatte, Michelle Renee


    Infertility affects an estimated 15% of couples globally, amounting to 48.5 million couples. Males are found to be solely responsible for 20-30% of infertility cases and contribute to 50% of cases overall. However, this number does not accurately represent all regions of the world. Indeed, on a global level, there is a lack of accurate statistics on rates of male infertility. Our report examines major regions of the world and reports rates of male infertility based on data on female infertility. Our search consisted of systematic reviews, meta-analyses, and population-based studies by searching the terms "epidemiology, male infertility, and prevalence." We identified 16 articles for detailed study. We typically used the assumption that 50% of all cases of infertility are due to female factors alone, 20-30% are due to male factors alone, and the remaining 20-30% are due to a combination of male and female factors. Therefore, in regions of the world where male factor or rates of male infertility were not reported, we used this assumption to calculate general rates of male factor infertility. Our calculated data showed that the distribution of infertility due to male factor ranged from 20% to 70% and that the percentage of infertile men ranged from 2·5% to 12%. Infertility rates were highest in Africa and Central/Eastern Europe. Additionally, according to a variety of sources, rates of male infertility in North America, Australia, and Central and Eastern Europe varied from 4 5-6%, 9%, and 8-12%, respectively. This study demonstrates a novel and unique way to calculate the distribution of male infertility around the world. According to our results, at least 30 million men worldwide are infertile with the highest rates in Africa and Eastern Europe. Results indicate further research is needed regarding etiology and treatment, reduce stigma & cultural barriers, and establish a more precise calculation.

  11. 8 ways to build collaborative teams. (United States)

    Gratton, Lynda; Erickson, Tamara J


    Executing complex initiatives like acquisitions or an IT overhaul requires a breadth of knowledge that can be provided only by teams that are large, diverse, virtual, and composed of highly educated specialists. The irony is, those same characteristics have an alarming tendency to decrease collaboration on a team. What's a company to do? Gratton, a London Business School professor, and Erickson, president of the Concours Institute, studied 55 large teams and identified those with strong collaboration despite their complexity. Examining the team dynamics and environment at firms ranging from Royal Bank of Scotland to Nokia to Marriott, the authors isolated eight success factors: (1) "Signature" relationship practices that build bonds among the staff, in memorable ways that are particularly suited to a company's business. (2) Role models of collaboration among executives, which help cooperation trickle down to the staff. (3) The establishment of a "gift culture," in which managers support employees by mentoring them daily, instead of a transactional "tit-for-tat culture", (4) Training in relationship skills, such as communication and conflict resolution. (5) A sense of community, which corporate HR can foster by sponsoring group activities. (6) Ambidextrous leadership, or leaders who are both task-oriented and relationship-oriented. (7) Good use of heritage relationships, by populating teams with members who know and trust one another. (8) Role clarity and task ambiguity, achieved by defining individual roles sharply but giving teams latitude on approach. As teams have grown from a standard of 20 members to comprise 100 or more, team practices that once worked well no longer apply. The new complexity of teams requires companies to increase their capacity for collaboration, by making long-term investments that build relationships and trust, and smart near-term decisions about how teams are formed and run.

    Heinemann, L


    mean that more patients are willing to start insulin therapy earlier than with conventional SC insulin therapy? With TI we have a product that has improved pharmacological properties (also in comparison to Exubera) for coverage of prandial insulin requirements. Subsequently, in the clinical trials performed, postprandial glycaemic excursions were lower than with SC injection of RHI or rapid-acting insulin analogues. This only in part (if at all) results in an improved metabolic control in general (= lower HbA1c) (see below). The outlook for 2011 is that there are chances that we shall have an inhaled insulin product on the market. Probably also the first OI will be submitted to the regulatory authorities for market approval or will even be available in less regulated markets. In order to select all relevant publications about new ways of insulin delivery I performed a PUBMED search and also checked the table of contents of a number of journals that publish heavily in this area of research as well references in the publications I found for additional references. Selection of the manuscripts from all publications was predominately based on the fact whether they presented data from clinical studies or not. The selected studies were critically reviewed for novelty and appropriate study design etc. In some cases also reviews about a given topic were selected if they provide relevant novel insights. © 2011 Blackwell Publishing Ltd.

CLASHEP was established in 2001 as a way of engaging young Latin American scientists in the field of particle physics - particularly in the experimental aspects of research. It has played an important role in encouraging Latin American institutes to collaborate with CERN and showing how non-Member-State physicists can work as equals with Member-State nationals. “CLASHEP reflects some of CERN’s guiding policies: enlarging its membership and involving new nations in its programmes,” says Nick Ellis, director of the CERN Schools of High-Ene...

  14. Changes in unique hues induced by chromatic surrounds. (United States)

    Klauke, Susanne; Wachtler, Thomas


    A chromatic surround can have a strong influence on the perceived hue of a stimulus. We investigated whether chromatic induction has similar effects on the perception of colors that appear pure and unmixed (unique red, green, blue, and yellow) as on other colors. Subjects performed unique hue settings of stimuli in isoluminant surrounds of different chromaticities. Compared with the settings in a neutral gray surround, unique hue settings altered systematically with chromatic surrounds. The amount of induced hue shift depended on the difference between stimulus and surround hues, and was similar for unique hue settings as for settings of nonunique hues. Intraindividual variability in unique hue settings was roughly twice as high as for settings obtained in asymmetric matching experiments, which may reflect the presence of a reference stimulus in the matching task. Variabilities were also larger with chromatic surrounds than with neutral gray surrounds, for both unique hue settings and matching of nonunique hues. The results suggest that the neural representations underlying unique hue percepts are influenced by the same neural processing mechanisms as the percepts of other colors.

  15. Non-unique Product Groups on Two Generators


    Carter, William Paul


    The main purpose of this paper is to better understand groups that do not have the unique product property. In particular, the goal is to better understand Promislow's example, G, of such a group. In doing so, we will develop methods for generating examples of other sets that do not have the unique product property. With these methods we can show that there exists other distinct 14 element, square, non-unique product sets in G that are not inversions or translations. Also, this paper answers ...

  18. Charter Schools and Student Compositions of Traditional Public Schools

    Directory of Open Access Journals (Sweden)

    Nevbahar Ertas


    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.

  19. Cultural Sensitiveness of School Goals and Students’ Failure in Turkey

    Directory of Open Access Journals (Sweden)

    Ismet Sahin


    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.

Moreover, the proof of uniqueness can be shown for either any purely electric or purely magnetic field configuration. The spacetime geometry is not crucial for the proof

  6. Practical relevance of pattern uniqueness in forensic science. (United States)

    Jayaprakash, Paul T


    Uniqueness being unprovable, it has recently been argued that individualization in forensic science is irrelevant and, probability, as applied for DNA profiles, should be applied for all identifications. Critiques against uniqueness have omitted physical matching, a realistic and tangible individualization that supports uniqueness. Describing case examples illustrating pattern matches including physical matching, it is indicated that individualizations are practically relevant for forensic science as they establish facts on a definitive basis providing firm leads benefitting criminal investigation. As a tenet of forensic identification, uniqueness forms a fundamental paradigm relevant for individualization. Evidence on the indeterministic and stochastic causal pathways of characteristics in patterns available in the related fields of science sufficiently supports the proposition of uniqueness. Characteristics involved in physical matching and matching achieved in patterned evidence existing in the state of nature are not events amenable for counting; instead these are ensemble of visible units occupying the entire pattern area stretching the probability of re-occurrence of a verisimilitude pattern into infinity offering epistemic support to uniqueness. Observational methods are as respectable as instrumental or statistical methods since they are capable of generating results that are tangible and obviously valid as in physical matching. Applying the probabilistic interpretation used for DNA profiles to the other patterns would be unbefitting since these two are disparate, the causal pathways of the events, the loci, in the manipulated DNA profiles being determinable. While uniqueness enables individualizations, it does not vouch for eliminating errors. Instead of dismissing uniqueness and individualization, accepting errors as human or system failures and seeking remedial measures would benefit forensic science practice and criminal investigation.

  7. Investigation of unique hue setting changes with ageing

    Chenyang Fu; Kaida Xiao; Dimosthenis Karatzas; Sophie Wuerger


    Clromatic sensitivity along the protan, deutan, and tritan lines and the loci of the unique hues (red, green,yellow, blue) for a very large sample (n = 185) of colour-normal observers ranging from 18 to 75 years of age are assessed. Visual judgments are obtained under normal viewing conditions using colour patches on self-luminous display under controlled adaptation conditions. Trivector discrimination thresholds show an increase as a function of age along the protan, deutan, and tritan axes, with the largest increase present along the tritan line, less pronounced shifts in unique hue settings are also observed. Based on the chromatic (protan, deutan, tritan) thresholds and using scaled cone signals, we predict the unique hue changes with ageing. A dependency on age for unique red and unique yellow for predicted hue angle is found. We conclude that the chromatic sensitivity deteriorates significantly with age, whereas the appearance of unique hues is much less affected, remaining almost constant despite the known changes in the ocular media.%@@ Clromatic sensitivity along the protan, deutan, and tritan lines and the loci of the unique hues (red, green,yellow, blue) for a very large sample (n = 185) of colour-normal observers ranging from 18 to 75 years of age are assessed.Visual judgments are obtained under normal viewing conditions using colour patches on self-luminous display under controlled adaptation conditions.Trivector discrimination thresholds show an increase as a function of age along the protan, deutan, and tritan axes, with the largest increase present along the tritan line, less pronounced shifts in unique hue settings are also observed.

  4. AIM satellite-based research bridges the unique scientific aspects of the mission to informal education programs globally (United States)

    Robinson, D.; Maggi, B.


    The Education and Public Outreach (EPO) component of the satellite-based research mission "Aeronomy of Ice In the Mesosphere" (AIM) will bridge the unique scientific aspects of the mission to informal education organizations. The informal education materials developed by the EPO will utilize AIM data and educate the public about the environmental implications associated with the data. This will assist with creating a scientifically literate workforce and in developing a citizenry capable of making educated decisions related to environmental policies and laws. The objective of the AIM mission is to understand the mechanisms that cause Polar Mesospheric Clouds (PMCs) to form, how their presence affects the atmosphere, and how change in the atmosphere affects them. PMCs are sometimes known as Noctilucent Clouds (NLCs) because of their visibility during the night from appropriate locations. The phenomenon of PMCs is an observable indicator of global change, a concern to all citizens. Recent sightings of these clouds over populated regions have compelled AIM educators to expand informal education opportunities to communities worldwide. Collaborations with informal organizations include: Museums/Science Centers; NASA Sun-Earth Connection Forum; Alaska Native Ways of Knowing Project; Amateur Noctilucent Cloud Observers Organization; National Parks Education Programs; After School Science Clubs; Public Broadcasting Associations; and National Public Radio. The Native Ways of Knowing Project is an excellent example of informal collaboration with the AIM EPO. This Alaska based project will assist native peoples of the state with photographing NLCs for the EPO website. It will also aid the EPO with developing materials for informal organizations that incorporate traditional native knowledge and science, related to the sky. Another AIM collaboration that will offer citizens lasting informal education opportunities is the one established with the United States National Parks

    Full Text Available We describe the uniqueness of the Bachelor of Science in Pharmaceutical Sciences (BSPS degree and the factors that contribute to this uniqueness. A total of 18 colleges and schools that offer a BSPS were identified in the literature and compared. A review of the current literature and university websites was conducted in order to compare and contrast the different BSPS programs. BSPS program directors’ perceptions were evaluated through a 14-item online survey instrument. Of the 16 programs surveyed, seven (43.8% responded to the survey. The respondents agreed that most of the BSPS graduates are placed (from the highest to the lowest at pharmacy school, postgraduate education and in the pharmaceutical industry. This is a timely review of coursework, program lengths and job opportunities for graduates of the BSPS. Currently, the BSPS programs have yet to receive a large amount of attention, but the importance in pharmaceutical education cannot be denied.

  7. Classical many-particle systems with unique disordered ground states (United States)

    Zhang, G.; Stillinger, F. H.; Torquato, S.


    Classical ground states (global energy-minimizing configurations) of many-particle systems are typically unique crystalline structures, implying zero enumeration entropy of distinct patterns (aside from trivial symmetry operations). By contrast, the few previously known disordered classical ground states of many-particle systems are all high-entropy (highly degenerate) states. Here we show computationally that our recently proposed "perfect-glass" many-particle model [Sci. Rep. 6, 36963 (2016), 10.1038/srep36963] possesses disordered classical ground states with a zero entropy: a highly counterintuitive situation . For all of the system sizes, parameters, and space dimensions that we have numerically investigated, the disordered ground states are unique such that they can always be superposed onto each other or their mirror image. At low energies, the density of states obtained from simulations matches those calculated from the harmonic approximation near a single ground state, further confirming ground-state uniqueness. Our discovery provides singular examples in which entropy and disorder are at odds with one another. The zero-entropy ground states provide a unique perspective on the celebrated Kauzmann-entropy crisis in which the extrapolated entropy of a supercooled liquid drops below that of the crystal. We expect that our disordered unique patterns to be of value in fields beyond glass physics, including applications in cryptography as pseudorandom functions with tunable computational complexity.

  8. Executive Functions Contribute Uniquely to Reading Competence in Minority Youth (United States)

    Jacobson, Lisa A.; Koriakin, Taylor; Lipkin, Paul; Boada, Richard; Frijters, Jan; Lovett, Maureen; Hill, Dina; Willcutt, Erik; Gottwald, Stephanie; Wolf, Maryanne; Bosson-Heenan, Joan; Gruen, Jeffrey R.; Mahone, E. Mark


    Competent reading requires various skills beyond those for basic word reading (i.e., core language skills, rapid naming, phonological processing). Contributing “higher-level” or domain-general processes include information processing speed and executive functions (working memory, strategic problem solving, attentional switching). Research in this area has relied on largely Caucasian samples, with limited representation of children from racial or ethnic minority groups. This study examined contributions of executive skills to reading competence in 761 children of minority backgrounds. Hierarchical linear regressions examined unique contributions of executive functions (EF) to word reading, fluency, and comprehension. EF contributed uniquely to reading performance, over and above reading-related language skills; working memory contributed uniquely to all components of reading; while attentional switching, but not problem solving, contributed to isolated and contextual word reading and reading fluency. Problem solving uniquely predicted comprehension, suggesting that this skill may be especially important for reading comprehension in minority youth. Attentional switching may play a unique role in development of reading fluency in minority youth, perhaps as a result of the increased demand for switching between spoken versus written dialects. Findings have implications for educational and clinical practice with regard to reading instruction, remedial reading intervention, and assessment of individuals with reading difficulty.

  10. Child Abuseby Teachers and Legal Ways to Encounterin Rural Areas

    Directory of Open Access Journals (Sweden)

    Mohtaram Rabbani


    Full Text Available Abstract Many children closely interact with teachers for nine months out of the year and schools are one of the safest places for students to be educated and teachers have a vital role for this education. Teachers should prevent from different kinds of child abuses and have an important role for preventing from child abuse. The primary purpose of this literature review study is to investigate of the phenomenon of child abuse within the school environment by teachers. The second aim of this paper is to determine the legal ways in different countries to encounter with physical child abuse by teachers. Child abuseby teachers has an in depth influence on children’s behaviors and their academic achievements. Abused children have been found to suffer from extreme deficits in school, exhibit poor academic performance, antisocial behaviour, poor self-respect, higher criminal behaviour rates, scepticism of adults, and central nervous system functioning. The findings of this paper showed that there are many reported cases of child abuse by teachers in rural areas, nevertheless, many countries banned or restricted physical abuse or corporal punishment and made legal decisions.

  18. Uniqueness: skews bit occurrence frequencies in randomly generated fingerprint libraries. (United States)

    Chen, Nelson G


    Requiring that randomly generated chemical fingerprint libraries have unique fingerprints such that no two fingerprints are identical causes a systematic skew in bit occurrence frequencies, the proportion at which specified bits are set. Observed frequencies (O) at which each bit is set within the resulting libraries systematically differ from frequencies at which bits are set at fingerprint generation (E). Observed frequencies systematically skew toward 0.5, with the effect being more pronounced as library size approaches the compound space, which is the total number of unique possible fingerprints given the number of bit positions each fingerprint contains. The effect is quantified for varying library sizes as a fraction of the overall compound space, and for changes in the specified frequency E. The cause and implications for this systematic skew are subsequently discussed. When generating random libraries of chemical fingerprints, the imposition of a uniqueness requirement should either be avoided or taken into account.

  19. Word from the CSO - CERN’s unique scientific breadth

    CERN Multimedia


    Whilst we are all clearly focused on completion of the LHC and the detectors around it and look forward to a successful start of operations later this year, we should not forget that CERN has yet more to offer in addition to this highest priority programme ‘at the energy frontier’. Indeed, CERN also attracts a large scientific community seizing the opportunities offered by its other facilities. Sometimes I wonder whether we are not too modest and should not emphasize more CERN’s unique scientific breadth. ISOLDE, at the PS Booster, relies on innovative techniques to produce results at the forefront of nuclear physics very cost-effectively. nTOF has provided unique measurements of interest to nuclear technology, nuclear astrophysics and basic nuclear physics, and still has an ambitious programme ahead of it after refurbishment of the target. Another unique facility is the Antiproton Decelerator, at which the study of antimatter is being pursued with ingenious experiment...

  20. RUCS: Rapid identification of PCR primers for unique core sequences

    DEFF Research Database (Denmark)

    Thomsen, Martin Christen Frølund; Hasman, Henrik; Westh, Henrik


    Designing PCR primers to target a specific selection of whole genome sequenced strains can be a long, arduous, and sometimes impractical task. Such tasks would benefit greatly from an automated tool to both identify unique targets, and to validate the vast number of potential primer pairs...... for the targets in silico . Here we present RUCS, a program that will find PCR primer pairs and probes for the unique core sequences of a positive genome dataset complement to a negative genome dataset.

  1. Flexible and efficient genome tiling design with penalized uniqueness score

    Directory of Open Access Journals (Sweden)

    Du Yang


    Full Text Available Abstract Background As a powerful tool in whole genome analysis, tiling array has been widely used in the answering of many genomic questions. Now it could also serve as a capture device for the library preparation in the popular high throughput sequencing experiments. Thus, a flexible and efficient tiling array design approach is still needed and could assist in various types and scales of transcriptomic experiment. Results In this paper, we address issues and challenges in designing probes suitable for tiling array applications and targeted sequencing. In particular, we define the penalized uniqueness score, which serves as a controlling criterion to eliminate potential cross-hybridization, and a flexible tiling array design pipeline. Unlike BLAST or simple suffix array based methods, computing and using our uniqueness measurement can be more efficient for large scale design and require less memory. The parameters provided could assist in various types of genomic tiling task. In addition, using both commercial array data and experiment data we show, unlike previously claimed, that palindromic sequence exhibiting relatively lower uniqueness. Conclusions Our proposed penalized uniqueness score could serve as a better indicator for cross hybridization with higher sensitivity and specificity, giving more control of expected array quality. The flexible tiling design algorithm incorporating the penalized uniqueness score was shown to give higher coverage and resolution. The package to calculate the penalized uniqueness score and the described probe selection algorithm are implemented as a Perl program, which is freely available at

  2. Human uniqueness-self-interest and social cooperation. (United States)

    Okada, Daijiro; Bingham, Paul M


    Humans are unique among all species of terrestrial history in both ecological dominance and individual properties. Many, or perhaps all, of the unique elements of this nonpareil status can be plausibly interpreted as evolutionary and strategic elements and consequences of the unprecedented intensity and scale of our social cooperation. Convincing explanation of this unique human social adaptation remains a central, unmet challenge to the scientific enterprise. We develop a hypothesis for the ancestral origin of expanded cooperative social behavior. Specifically, we present a game theoretic analysis demonstrating that a specific pattern of expanded social cooperation between conspecific individuals with conflicts of interest (including non-kin) can be strategically viable, but only in animals that possess a highly unusual capacity for conspecific violence (credible threat) having very specific properties that dramatically reduce the costs of coercive violence. The resulting reduced costs allow preemptive or compensated coercion to be an instantaneously self-interested behavior under diverse circumstances rather than in rare, idiosyncratic circumstances as in actors (animals) who do not have access to inexpensive coercive threat. Humans are apparently unique among terrestrial organisms in having evolved conspecific coercive capabilities that fulfill these stringent requirements. Thus, our results support the proposal that access to a novel capacity for projection of coercive threat might represent the essential initiating event for the evolution of a human-like pattern of social cooperation and the subsequent evolution of the diverse features of human uniqueness. Empirical evidence indicates that these constraints were, in fact, met only in our evolutionary lineage. The logic for the emergence of uniquely human cooperation suggested by our analysis apparently accounts simply for the human fossil record.

  3. Is the Milky Way an interacting galaxy?

    International Nuclear Information System (INIS)

    Verschuur, G.L.


    The Milky Way Galaxy is an interacting galaxy, according to radio astronomers. The disk of stars we live in is linked to the Magellanic Clouds, our Galaxy's satellites, by an enormous arc of neutral hydrogen called the Magellanic Stream. These startling facts have recently been established by piecing together many seemingly unrelated bits of evidence into a new picture of our Milky Way Galaxy. The discoveries that led up to this grand picture of the Milky Way's interaction data back over fifty years to create one of the best detective stories in modern astronomy. The realization that ours is an interacting galaxy is only the latest result of an intensive effort to map the Milky Way. Since the 1930s, astronomers have tried to discover just how our Galaxy is built. Charting the Milky Way hasn't been easy, because we are inside it and our view of the Milky Way is obscured by cosmic dust. This dust creates a region called the zone of avoidance, a band centered along the galactic plane that blocks visible light from objects beyond nearby objects in the Galaxy. Thus radio astronomers have become the Milky Way mappers because cosmic radio waves penetrate the dust and reveal the grand scheme of our Galaxy

    Huajian Cai


    Full Text Available Past research has documented various cultural and psychological changes in contemporary China. In two studies, we examine how Chinese people’s need for uniqueness (NFU also has changed. In Study 1, we found a significant cross-generational increase in Chinese participants’ self-reported NFU. In Study 2, we sampled the names of Chinese newborn babies over the last five decades and found that parents have been increasingly likely to use unique characters to name their children. These findings suggest that the NFU has been rising in China, a historically collectivistic-oriented society. Theoretical and practical implications of our findings were discussed.

    Pogodina A.V.


    Full Text Available This paper analyzes the representations of the major educational process participants (students, teachers and representatives of the school administration concerning the various elements of the socio-psychological situation in the educational institution. We assumed that the substantive characteristics of socio-psychological situation are reflected in the representations of the major participants of the educational process, which can help to define the degree of homogeneity of representations in students and teachers, as well as the uniqueness of socio-psychological situation in an educational institution. We describe the progress and the results of research conducted in Moscow on the basis of state educational institutions of various profiles (gymnasium with intensive study of English secondary school with ethno-cultural component, which was attended by 308 people, 235 of whom were students, and 73 were teachers and representatives of the school administration. We reveal the features of representation of different participants of the educational process about such elements of socio-psychological situation as leadership style, the type of organizational culture and the parameters of social and psychological climate in the educational institution. We describe significant differences in the expression of the elements of social and psychological situation in educational institutions of various types.

    A. Colin Cameron; Jonah B. Gelbach; Douglas L. Miller; Doug Miller


    In this paper we propose a variance estimator for the OLS estimator as well as for nonlinear estimators such as logit, probit and GMM. This variance estimator enables cluster-robust inference when there is two-way or multi-way clustering that is non-nested. The variance estimator extends the standard cluster-robust variance estimator or sandwich estimator for one-way clustering (e.g. Liang and Zeger (1986), Arellano (1987)) and relies on similar relatively weak distributional assumptions.

Our validation of the random assignment shows comparable socioeconomic backgroun...

  12. Gaia: 3-dimensional census of the Milky Way Galaxy (United States)

    Gilmore, Gerard


    Astrometry from space has unique advantages over ground-based observations: the all-sky coverage, relatively stable, and temperature and gravity invariant, operating environment delivers precision, accuracy and sample volume several orders of magnitude greater than ground-based results. Even more importantly, absolute astrometry is possible. The European Space Agency Cornerstone mission Gaia is delivering that promise. Gaia provides 5-D phase space measurements, 3 spatial coordinates and 2 space motions in the plane of the sky, for a representative sample of the Milky Way's stellar populations (over 2 billion stars, being 1% of the stars over 50% of the radius). Full 6-D phase space data are delivered from line-of-sight (radial) velocities for the 300 million brightest stars. These data make substantial contributions to astrophysics and fundamental physics on scales from the Solar System to cosmology. A knowledge revolution is underway.

  13. Acoustic topological insulator and robust one-way sound transport (United States)

    He, Cheng; Ni, Xu; Ge, Hao; Sun, Xiao-Chen; Chen, Yan-Bin; Lu, Ming-Hui; Liu, Xiao-Ping; Chen, Yan-Feng


    Topological design of materials enables topological symmetries and facilitates unique backscattering-immune wave transport. In airborne acoustics, however, the intrinsic longitudinal nature of sound polarization makes the use of the conventional spin-orbital interaction mechanism impossible for achieving band inversion. The topological gauge flux is then typically introduced with a moving background in theoretical models. Its practical implementation is a serious challenge, though, due to inherent dynamic instabilities and noise. Here we realize the inversion of acoustic energy bands at a double Dirac cone and provide an experimental demonstration of an acoustic topological insulator. By manipulating the hopping interaction of neighbouring ’atoms’ in this new topological material, we successfully demonstrate the acoustic quantum spin Hall effect, characterized by robust pseudospin-dependent one-way edge sound transport. Our results are promising for the exploration of new routes for experimentally studying topological phenomena and related applications, for example, sound-noise reduction.

  14. A unique memory process modulated by emotion underpins successful odor recognition and episodic retrieval in humans

    Directory of Open Access Journals (Sweden)

    Anne-Lise eSaive


    Full Text Available We behaviorally explore the link between olfaction, emotion and memory by testing the hypothesis that the emotion carried by odors facilitates the memory of specific unique events. To investigate this idea, we used a novel behavioral approach inspired by a paradigm developed by our team to study episodic memory in a controlled and as ecological as possible way in humans. The participants freely explored three unique and rich laboratory episodes; each episode consisted of three unfamiliar odors (What positioned at three specific locations (Where within a visual context (Which context. During the retrieval test, which occurred 24 to 72 hours after the encoding, odors were used to trigger the retrieval of the complex episodes. The participants were proficient in recognizing the target odors among distractors and retrieving the visuospatial context in which they were encountered. The episodic nature of the task generated high and stable memory performances, which were accompanied by faster responses and slower and deeper breathing. Successful odor recognition and episodic memory were not related to differences in odor investigation at encoding. However, memory performances were influenced by the emotional content of the odors, regardless of odor valence, with both pleasant and unpleasant odors generating higher recognition and episodic retrieval than neutral odors. Finally, the present study also suggested that when the binding between the odors and the spatio-contextual features of the episode was successful, the odor recognition and the episodic retrieval collapsed into a unique memory process that began as soon as the participants smelled the odors.

  16. Psychological aspects of human cloning and genetic manipulation: the identity and uniqueness of human beings. (United States)

    Morales, N M


    Human cloning has become one of the most controversial debates about reproduction in Western civilization. Human cloning represents asexual reproduction, but the critics of human cloning argue that the result of cloning is not a new individual who is genetically unique. There is also awareness in the scientific community, including the medical community, that human cloning and the creation of clones are inevitable. Psychology and other social sciences, together with the natural sciences, will need to find ways to help the healthcare system, to be prepared to face the new challenges introduced by the techniques of human cloning. One of those challenges is to help the healthcare system to find specific standards of behaviour that could be used to help potential parents to interact properly with cloned babies or children created through genetic manipulation. In this paper, the concepts of personality, identity and uniqueness are discussed in relationship to the contribution of twin studies in these areas. The author argues that an individual created by human cloning techniques or any other type of genetic manipulation will not show the donor's characteristics to the extent of compromising uniqueness. Therefore, claims to such an effect are needlessly alarmist.

  17. The social structure of schooling. (United States)

    Dornbusch, S M; Glasgow, K L; Lin, I C


    The term social structure refers to a relatively enduring pattern of social arrangements or interrelations within a particular society, organization, or group. This chapter reviews how the social structure of the larger society and the organizational structure of schools affect the educational process within American schools. The institutional context of schooling is first discussed. The ideology of mass education, social stratification, status attainment, credentialism, and the emphasis on ability differences are considered. The focus then shifts to the organizational structure of schools, beginning with a discussion of the external social context for school organization. Attention is given to professionalism and bureaucracy, institutional forms of organization, decentralized control, and community influences. Finally, the internal structure of school organization is considered: teachers' working conditions, status differences among students, and curriculum tracking. Throughout, the emphasis is on ways in which social structure influences what is taught in school, how it is taught, and what is learned.

  9. Sufficient conditions for uniqueness of the weak value

    International Nuclear Information System (INIS)

    Dressel, J; Jordan, A N


    We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned average using the contextual values formalism introduced in Dressel, Agarwal and Jordan (2010 Phys. Rev. Lett. We also respond to criticism of our work by Parrott (arXiv:1105.4188v1) concerning a proposed counter-example to the uniqueness of the definition of the generalized weak value. The counter-example does not satisfy our prescription in the case of an underspecified measurement context. We show that when the contextual values formalism is properly applied to this example, a natural interpretation of the measurement emerges and the unique definition in the weak limit holds. We also prove a theorem regarding the uniqueness of the definition under our sufficient conditions for the general case. Finally, a second proposed counter-example by Parrott (arXiv:1105.4188v6) is shown not to satisfy the sufficiency conditions for the provided theorem. (paper)

  6. Cone photoreceptor sensitivities and unique hue chromatic responses: correlation and causation imply the physiological basis of unique hues.

    Directory of Open Access Journals (Sweden)

    Ralph W Pridmore

    Full Text Available This paper relates major functions at the start and end of the color vision process. The process starts with three cone photoreceptors transducing light into electrical responses. Cone sensitivities were once expected to be Red Green Blue color matching functions (to mix colors but microspectrometry proved otherwise: they instead peak in yellowish, greenish, and blueish hues. These physiological functions are an enigma, unmatched with any set of psychophysical (behavioral functions. The end-result of the visual process is color sensation, whose essential percepts are unique (or pure hues red, yellow, green, blue. Unique hues cannot be described by other hues, but can describe all other hues, e.g., that hue is reddish-blue. They are carried by four opponent chromatic response curves but the literature does not specify whether each curve represents a range of hues or only one hue (a unique over its wavelength range. Here the latter is demonstrated, confirming that opponent chromatic responses define, and may be termed, unique hue chromatic responses. These psychophysical functions also are an enigma, unmatched with any physiological functions or basis. Here both enigmas are solved by demonstrating the three cone sensitivity curves and the three spectral chromatic response curves are almost identical sets (Pearson correlation coefficients r from 0.95-1.0 in peak wavelengths, curve shapes, math functions, and curve crossover wavelengths, though previously unrecognized due to presentation of curves in different formats, e.g., log, linear. (Red chromatic response curve is largely nonspectral and thus derives from two cones. Close correlation combined with deterministic causation implies cones are the physiological basis of unique hues. This match of three physiological and three psychophysical functions is unique in color vision.

Unique hues cannot be described by other hues, but can describe all other hues, e.g., that hue is reddish-blue. They are carried by four opponent chromatic response curves but the literature does not specify whether each curve represents a range of hues or only one hue (a unique) over its wavelength range. Here the latter is demonstrated, confirming that opponent chromatic responses define, and may be termed, unique hue chromatic responses. These psychophysical functions also are an enigma, unmatched with any physiological functions or basis. Here both enigmas are solved by demonstrating the three cone sensitivity curves and the three spectral chromatic response curves are almost identical sets (Pearson correlation coefficients r from 0.95-1.0) in peak wavelengths, curve shapes, math functions, and curve crossover wavelengths, though previously unrecognized due to presentation of curves in different formats, e.g., log, linear. (Red chromatic response curve is largely nonspectral and thus derives from two cones.) Close correlation combined with deterministic causation implies cones are the physiological basis of unique hues. This match of three physiological and three psychophysical functions is unique in color vision.

  8. Two-way and three-way negativities of three-qubit entangled states

    International Nuclear Information System (INIS)

    Sharma, S. Shelly; Sharma, N. K.


    We propose to quantify three-qubit entanglement using global negativity along with K-way negativities, where K=2 and 3. The principle underlying the definition of K-way negativity for pure and mixed states of N subsystems is a positive partial transpose sufficient condition. However, K-way partial transpose with respect to a subsystem is defined so as to shift the focus to K-way coherences instead of K subsystems of the composite system. A quantum state of a three-qubit system is characterized by the coherences measured by global, two-way, and three-way negativities. For a canonical state of three-qubit system, entanglement measures for genuine tripartite entanglement, W-like entanglement, and bipartite entanglement can be related to two-way and three-way negativities

  13. Administrator Leadership Styles and Their Impact on School Nursing. (United States)

    Davis, Charles R


    In comparison to other professional staff in an educational based setting, the registered professional school nurse has unique roles, responsibilities, education, training, and scope of practice. In carrying out this unique and specialized role, school nurses operate under a building administrator, the leader of the building and often the immediate supervisor of the school nurse. In addition, many school nurses in small districts are the only registered professional nurse employed by the school. The building administrator's leadership style not only sets the tone for the day-to-day operations in the school but also impacts the school nurse functioning and program implementation. This article reviews the three most common types of leadership styles as defined by Kurt Lewin-laissez-faire, democratic, and coercive/authoritarian-and their potential impact on school nursing practice. In addition, the article provides recommendations for school nurses for successful practice with regard to supervisor leadership styles.

  15. Using Synthetic Controls to Evaluate the Effect of Unique Interventions: The Case of Say Yes to Education. (United States)

    Bifulco, Robert; Rubenstein, Ross; Sohn, Hosung


    "Place-based" scholarships seek to improve student outcomes in urban school districts and promote urban revitalization in economically challenged cities. Say Yes to Education is a unique district-wide school reform effort adopted in Syracuse, NY, in 2008. It includes full-tuition scholarships for public and private universities, coupled with extensive wraparound support services in schools. This study uses synthetic control methods to evaluate the effect of Say Yes on district enrollment and graduation rates. It also introduces the synthetic control method and provides guidance for its use in evaluating single-site interventions. Combining school district-level data from the National Center for Education Statistics' Common Core of Data and New York State School Report Cards, this article uses synthetic control methods to construct a synthetic comparison district to estimate counterfactual enrollment and graduation trends for Syracuse. We find that Say Yes to Education was associated with enrollment increases in the Syracuse City School District, a district that had previously experienced decades of sustained enrollment declines. We do not find consistent evidence of changes in graduation rates following adoption of the program. Graduation rate analyses demonstrate that estimates of treatment effects can be sensitive to choices that the researcher has to make in applying synthetic control methods, particularly when pretreatment outcome measures appear to have considerable amounts of noise.

  2. Do cracks melt their way through solids?

    International Nuclear Information System (INIS)

    Okamoto, P. R.


    Real-time, in situ fracture studies in the high-voltage electron microscope (HVEM) show that microscopically thin regions of amorphous NiTi form ahead of moving crack tips in the B2-NiTi intermetallic compound during tensile straining at temperatures equal to or below 600K. The upper cutoff temperature of 600K for this stress-induced melting (or amorphization) is identical to the upper cutoff temperatures reported in the literature for both heavy-ion-induced amorphization of the intermetallic NiTi and ion-beam-mixing-induced amorphization of Ni and Ti multilayer. These results, together with the fact that the higher crystallization temperatures (∼800K)of unrelaxed amorphous NiTi alloys obtained by rapid quenching can also be reduced to, but not lower than 600K, by heavy-ion irradiation, strongly suggest that structural relaxation processes enhanced or induced by dynamic atomic disordering allow the formation of a unique, fully-relaxed glassy state which is characterized by a unique isothermal crystallization temperature. We believe that this unique temperature is the Kauzmann glass-transition temperature, corresponding to the ideal glass having the same entropy as the crystalline state. As the glassy state with the lowest global free energy, the preferential formation of this ideal glass by disorder-induced amorphization processes can be understood as the most energetically-favored, kinetically-constrained melting response of crystalline materials driven far from equilibrium at low temperatures

    How a state chooses to design its system of funding schools is ultimately a question of education governance, determining who--state policymakers, school districts, or school principals--gets to make the decisions about how and where funding is spent. States have two primary ways of funding schools: the foundation, or base funding that is intended…

  8. Temporal analysis of social networks using three-way DEDICOM.

    Energy Technology Data Exchange (ETDEWEB)

    Bader, Brett William; Harshman, Richard A. (University of Ontario, London, Ontario, Canada); Kolda, Tamara Gibson (Sandia National Laboratories, Livermore, CA)


    DEDICOM is an algebraic model for analyzing intrinsically asymmetric relationships, such as the balance of trade among nations or the flow of information among organizations or individuals. It provides information on latent components in the data that can be regarded as ''properties'' or ''aspects'' of the objects, and it finds a few patterns that can be combined to describe many relationships among these components. When we apply this technique to adjacency matrices arising from directed graphs, we obtain a smaller graph that gives an idealized description of its patterns. Three-way DEDICOM is a higher-order extension of the model that has certain uniqueness properties. It allows for a third mode of the data, such as time, and permits the analysis of semantic graphs. We present an improved algorithm for computing three-way DEDICOM on sparse data and demonstrate it by applying it to the adjacency tensor of a semantic graph with time-labeled edges. Our application uses the Enron email corpus, from which we construct a semantic graph corresponding to email exchanges among Enron personnel over a series of 44 months. Meaningful patterns are recovered in which the representation of asymmetries adds insight into the social networks at Enron.

  10. A Planetary Geophysicist Does EPO: Lessons Learned Along the Way (United States)

    Kiefer, W. S.


    My "day job" is numerical modeling of the interiors of the terrestrial planets, but I have also done EPO projects for the last 17 years while at the Lunar and Planetary Institute. These range from single, hour long talks in classrooms or astronomy clubs, to week-long summer workshops for teachers and librarians, and even semester-long programs, along with a number of curriculum development projects. EPO projects are a great way to help develop both the next generation of scientists and, more importantly, of scientifically literate citizens and taxpayers. Here are a few lessons learned along the way in the school of hard knocks. (1) An engaging delivery style is even more important in EPO presentations than it is in college lectures or conference presentations. Emphasize a few key concepts rather than numerous facts, and keep the jargon out. Good analogies can go a long way towards explaining a concept to any age group. I teach the role of size in planetary cooling by first asking students how long it takes to cook food of various sizes (a hamburger, roast beef, turkey). (2) If you will be working with a group of students for more than one class period, classroom friendly activities strengthen the learning process. Such activities do not need to be elaborate - when teaching about the Moon, I sometimes assign students to take their parents outside at night and show them how to find lava flows on the Moon. Teachers usually need to have classroom activities that are aligned to state or national teaching standards. Fortunately, many effective, standards-aligned activities already exist, so you don't need to reinvent the wheel. For a useful listing of planetary science and astronomy activities, see the LPI website (3) Although EPO work can be personally rewarding, it is not always well rewarded in a professional context, and it can be difficult to find the time and financial resources to sustain major projects. We sometimes use a

  12. Teachers' Coping Strategies for Teaching Science in a ``Low-Performing'' School District (United States)

    Moore, Felicia M.


    This study describes how teachers use their personal knowledge of a school district and their students to cope with teaching under stressful situations associated with economic, social, and institutional factors. The 3 teachers dealt with these issues in unique ways, focusing on helping students to overcome negative perceptions, value the importance of an education, and build strong relationships. A model of multicultural science professional development is proposed that complements the strengths that these teachers have. A task for science educators working with teachers and administration in schools and districts that are “critically low performing” is to support everyone in implementing pedagogical methods aimed at empowerment, social justice, and high achievement for all students.

  14. Student nurses as school nurse extenders. (United States)

    Rossman, Carol L; Dood, Florence V; Squires, Darcy A


    The severe underuse of school nurses leaves students with unaddressed health needs that impact their safety and learning ability. An undergraduate pediatric clinical focusing on nursing students and the role of a school nurse in an elementary school setting can be a unique approach to combining the needs of school children and educating student nurses. One school of nursing created such a project to help address these needs and collect data on the activities student nurses performed in school nurse role and their impact on student health. This project serves as both a practice improvement project and an innovation in pediatric clinical education. The purposes of this project were to quantify baccalaureate nursing student activities related to the school nurse role and to evaluate the results that have the potential to impact on student health in an urban elementary school.

  16. Unique Migraine Subtypes, Rare Headache Disorders, and Other Disturbances. (United States)

    Goadsby, Peter J


    The medical aphorism that common things happen commonly makes unique (and less common) migraine subtypes especially appropriate to review for the general neurologist. This article also identifies some rare headache disorders and other disturbances, and offers strategies to manage them. This article discusses migraine with brainstem aura, which is troublesome clinically and has had a change in terminology in the International Classification of Headache Disorders, Third Edition, beta version (ICHD-3 beta), and hemiplegic migraine, which is also troublesome in practice. The rare headache disorder hypnic headache and the exploding head syndrome are also discussed. When hypnic headache is recognized, it is eminently treatable, while exploding head syndrome is a benign condition with no reported consequences. Unique migraine subtypes, rare headache disorders, and other disturbances present to neurologists. When recognized, they can often be managed very well, which offers significant benefits to patients and practice satisfaction to neurologists.

  17. Solitary intraosseous neurofibroma: Report of a unique case

    Directory of Open Access Journals (Sweden)

    Sagar Satish Jangam


    Full Text Available Neural tumors located centrally in jaw bones are relatively rare compared with soft tissue neurofibromas. Less than 50 cases have been reported in the literature with a predilection for mandible. This article aims to elucidate a unique case of intraosseous neurofibroma of mandible in a 62-year-old edentulous female patient associated with facial asymmetry due to the swelling extending from the right body of mandible to left body of mandible. The uniqueness of this case is related to the age and extensiveness of this lesion. A review of clinical, radiographic, histological, and immunohistochemical features, and the surgical management pertaining to this case are discussed along with a review of the literature.

    Renahan, Navanith; Varma, R Balagopal; Kumaran, Parvathy; Xavier, Arun M


    The number of deaf children has dramatically increased in the past few decades. These children present to the pediatric dentist a unique set of challenges mostly pertaining to the establishment of communication with them. There have been very few attempts in the past to break down these challenges and formulate a strategy on how to manage them effectively. This is a case report of a child who was successfully managed using two different modes of communication. Finally, the advantages and disadvantages are mentioned, and a common strategy incorporating the positives of both the methods has been devised. Renahan N, Varma RB, Kumaran P, Xavier AM. Unique Approach to Dental Management of Children with Hearing Impairment. Int J Clin Pediatr Dent 2017;10(1):107-110.

  19. Concentration and mindfulness meditations: unique forms of consciousness? (United States)

    Dunn, B R; Hartigan, J A; Mikulas, W L


    Electroencephalographic (EEG) recordings from 19 scalp recording sites were used to differentiate among two posited unique forms of mediation, concentration and mindfulness, and a normal relaxation control condition. Analyzes of all traditional frequency bandwidth data (i.e., delta 1-3 Hz; theta, 4-7 Hz; alpha, 8-12 Hz; beta 1, 13-25 Hz; beta 2, 26-32 Hz) showed strong mean amplitude frequency differences between the two meditation conditions and relaxation over numerous cortical sites. Furthermore, significant differences were obtained between concentration and mindfulness states at all bandwidths. Taken together, our results suggest that concentration and mindfulness "meditations" may be unique forms of consciousness and are not merely degrees of a state of relaxation.

  20. On the Existence and Uniqueness of the Scientific Method. (United States)

    Wagensberg, Jorge


    The ultimate utility of science is widely agreed upon: the comprehension of reality. But there is much controversy about what scientific understanding actually means, and how we should proceed in order to gain new scientific understanding. Is there a method for acquiring new scientific knowledge? Is this method unique and universal? There has been no shortage of proposals, but neither has there been a shortage of skeptics about these proposals. This article proffers for discussion a potential scientific method that aspires to be unique and universal and is rooted in the recent and ancient history of scientific thinking. Curiously, conclusions can be inferred from this scientific method that also concern education and the transmission of science to others.
